The main application of fiberglass continuous mat

Fiberglass continuous mat is a kind of glass fiber mat, which is also widely use to FRP lines, the main application is as follows:

1, pultruded profiles. Because of the pultrusion and pultrusion products are produced by closed mold, without environmental pollution, good dimensional stability, no leftover waste, etc., it is a fiberglass molding method and fiberglass products with broad prospects for development. But there is a biggest drawback for pultruded product, that has a high radial strength, small hoop strength, easy to crack. Application of continuous felt as hoop reinforcing material to make up for its shortcomings, therefore, continuous mat is an indispensable reinforcement for pultruded profiles.

2, RTMVI process. Because continuous mat with high adhesive strength, fluffy porosity, moderate permeability of resin and good erosion resistance performance, fiberglass chopped strand mat is widely used in the RTM process to produce the glass fiber reinforced plastic doors and windows, wind turbines base and other accessories.

3, automotive interior parts. Continuous mat is mainly used for sun visors, rear decorative panels, spare tire cover and fenders. Because of the high strength, good decorative effect, it has been widely used to the Mercedes-Benz, BMW and other models.

        4, dry-type transformers. Dry-type transformers main application is same to glass fiber chopped strand mat, but the strength of continuous mat is higher than chopped mat, on the requirements of the occasion and the product must be used fiberglass continuous mat. Many domestic dry-type transformer manufacturers are using continuous mat.

The FRP Cantilever Sidewalk

FRP cantilever sidewalk is one kind of new sidewalk which using glass fiber reinforced plastic material.Concrete sidewalks have a long and storied history. According to researchers, they can be traced to ancient Rome, where lime and volcanic rock were first mixed to make mortar. Concrete is still the go-to material, but its drawbacks are obvious. Who hasn’t tripped over a crack or stubbed a toe on an uneven sidewalk surface? 

Regardless, sidewalks continue to play an important role in the transportation arena, particularly in areas where pedestrians must safely cross vehicle bridges. These pedestrians understandably want to be separated from motor traffic whenever possible. According to People For Bikes’ Green Lane Project, only 78 protected bike lanes existed nationwide before 2011. As of this year, fiberglass chopped strand mat the number of protected bike lanes has grown to 213. The implementation of these protected lanes is a huge challenge for bridge owners, who must meet weight limits if considering concrete for both the bridge structure and elevated access.

In most cases, decreasing vehicle lanes sizes to accommodate a pedestrian crossing just isn’t practical. And, constructing a separate bridge carries a high price tag. Is there a better solution?

Walk this way! A typical FRP cantilever sidewalk on steel stringers balances light weight with lower costs. Composite Advantage delivers prefabricated, numbered and ordered sections for easy, quick installation on support beams attached to the vehicle bridge. Owners reap long term savings thanks to the natural corrosion resistance and low maintenance of FRP material.

The main application of fiberglass chopped strand mat

Fiberglass chopped strand mat are widely used in the production of FRP products. The main areas are as follow:

1. The car roof and interior. Car roof interior usually use the mat of 100g or 150g. Some well-known domestic and foreign car companies have widely adopted. Such as BMW, Audi, Honda, Volkswagen, Nissan and so on.

2. Dry-type transformers with insulating material, which has safety and good energy saving effect. It is a new type of transformer is the development direction of the transformer. Application of E-glass fiber chopped strand mat solves the cracking problem between the winding conductor plagued the industry due to thermal expansion and contraction of the insulating material stress caused by different, and promote the development of dry-type transformers. Dry-type transformers have been widely used in aerospace, subways, nuclear power, airports, large buildings and the Three Gorges, Xiaolangdi Dam.

3. Sanitary ware. Sanitary ware substantially use more than 200g of glass fiber chopped strand mat, since the mat uniformity good, film is good, in the sanitary field has been widely used.

4. Other applications. Used in many areas of chemical preservative pipes, tanks, boats, ships, seats, body building structures, automotive sheet metal, wind power blades and so on.

The “Greenest” Pipe Material- Glass Fiber Reinforced Polyester

This is according to a new thesis from Sweco Norway that looked at pipe material properties in respect of sustainability and environment. Sweco Norway, initiated a new thesis research that compared four pipe materials. Pipe materials investigated were ductile iron, PVC (polyvinyl chloride),fiberglass chopped strand mat,GRP (glass fiber-reinforced polyester) and PE (polyethylene).

The purpose of the life cycle assessment was to consider the scope and distribution of environmental loads associated with pipe material, as a result of raw material extraction, material production, transportation, use and maintenance and finally waste management/disposal.

Material investigated account for more than 80% of the total length of the municipal water distribution network in Norway. In connection with the current, ongoing installation of new drinking water pipes in Norway, the same materials account for about 98% of the total pipe length. The life cycle analysis considered two pipe dimensions, 200mm and 600mm. The purpose of investigating two different dimensions was to uncover if environmental impacts changed significantly as the pipe diameter increased. Impacts pipe materials have in respect of climate change, including raw material, energy and transport. PVC stands out as having by far the largest contribution, both for raw materials and overall. GRP stands out in a positive way with a contribution of less than 2,000kg CO2-equivalents, which is about half of the emissions associated with ductile cast iron, representing the second smallest total contribution.

The thesis indicates that climate change is influenced by the use of pipe material, and that GRP provides lesser environmental load than other common pipe materials. PE and PVC accounts for the most significant negative impacts, according to the thesis.

The wind turbine without blades

Recently Vortex Bladeless not captured wind by the rotational movement of the wind turbine, but develop a wind power generator, called vortex, which is no blade of carbon fiber-intensive wind turbines. Vortex structure by shaking, fiberglass chopped strand mat and capturing energy generated.

The company claims that he had not simply just remove the blade, but it is designed to put any relevant parts are not. (no gear, key, etc.).

Vortex tower and generator integrated into a structure that requires fewer moving parts and less material to produce the same power. It also eliminates the cabin, and the blade support mechanism. Vortex claims, manufacturing production cost savings rough estimate of about 53% of the ordinary wind turbines. And the company claims, Vortex will produce 40% of the wind energy plant at low cost.

Vortex has five main sections: basic, rods, power generation systems, tuning systems and masts. Carbon fiber rods impart strength and flexibility of movement, while minimizing energy consumption. Mast is made of fiberglass and carbon fiber circular structure of light. Mast action of wind breaker produce oscillatory motion.

Company management warned, Vortex is not immune to fatigue. Wind can cause twisted structure and displacement, mainly in the elastic rod, especially in the lower part can withstand greater force. However, research into the stress confirm the work of the rod is far below the limit of the material. Computational model estimated installation work life is 32-96 years.

Currently Vortex has completed wind tunnel tests, the majority of research and development has been completed, they completed a working prototype.

FIberglass Woven Fabrics

Fiberglass Woven fabrics are produced by interlacing glass fibers in a regular pattern or weave style. As a result, weave controls a fabric’s stability, conformability to shape, surface characteristics, and fiberglass chopped strand mat, in many cases, the overall appearance for your part. And to fully understand the value that weaves deliver, we need to understand some fabric basics.

Filament vs. Fiber

Filament is a single strand of reinforcement. Thousands of filaments bundled together, running straight and parallel to one another, make up a fiber. For most reinforcements, like fiberglass, this is referred to as roving. In the case of carbon fiber, it is usually referred to as tow. Tow is measured in “K,” or thousands. For example, a 3K fabric means there are 3,000 filaments per fiber tow.

If the filaments of a fabric are twisted together, rather than running straight and parallel, they are referred to as a yarn. If yarn is used to produce fabric, it is referred to as cloth.

 

Warp vs. Fill

If you look at a roll of fabric, some of the fibers run in the direction of the roll and are continuous for the entire length of the roll. These fibers are known as the warp, and are often referred to as ends. The shorter fibers that run crosswise along the width of the fabric are known as fill and are referred to aspicks.

Fabric Count

Fabric count refers to the number of warp (ends) and fill (picks) fibers per inch. For example, a 24 x 22 fabric has 24 ends in every inch of fill direction and 22 picks in every inch of warp direction. Note that you count warp fibers in the fill direction and fill fibers in the warp direction.

The performance of fiberglass chopped strand mat

Fiberglass chopped strand mat is a major nonwoven glass fiber reinforced materials, which is chopping continuous glass fiber into certain length and uniformly distributed with polyester in  powder or emulsion form.

fiberglass chopped strand mat in addition to retaining the inherent characteristics, but also has many excellent features.

1, chopped strand mat has not tightly interwoven point as the fabric, which easy to adsorption resin, it has a large (50-75%) resin content in the products, thus making products has a tightness, no leakage, and improved the article of water and corrosion resistance to other media performance, but also improved the quality of appearance.

2, chopped strand mat not dense as fabric, thus for the production of reinforced products, easy thickening, and chopped strand mat production process less than the fabric, lower cost, use chopped strand mat can reduce the product cost.

3, The fiber in chopped strand mat no direction, It’s more roughness than the fabric surface, thus good adhesion between layers, to make products easy to layer, and strength of the products is the same for all direction.

4, fibers in chopped strand mat are not continuous, so if the products injury, it will damage to a small area, and the strength loss small.

5, the permeability of the resin, good wet out, good curing, which improve production efficiency, the resin-impregnated general rate is 60 seconds or less.

6, it has good peritoneal performance, easy to cut, easy construction and suitable for the production of more complex shapes products.

Chopped glass fiber reinforced thermoplastic composites material

Chopped glass fiber-reinforced thermoplastic composite material as a thermoplastic composites, which are widely used in transportation, chemical industry, fiberglass chopped strand mat construction, electronics and other industries.

According to the different resin matrix, the composites divide into three categories that metal matrix composite materials, inorganic non-metal matrix composites and polymer matrix composites. Resin-based composite material is divided into thermoset composites and thermoplastic composites (FRTP) categories. The thermoplastic composite is a thermoplastic resin as the matrix, a variety of fiber reinforced materials made of composite material. Such as PP, PA66, PA6, PBT belong to the thermoplastic resin.

Glass fiber reinforced thermoplastic composites (thermoplastics FRP) as a large class in FRTP, It has low density, high strength, thermoplastic good chemical resistance and excellent electrical properties, good processing performance advantages, its wide range of applications, mainly used in aerospace, automobile manufacturing industry, shipbuilding industry, chemical preservative, the electronics industry and construction engineering. The chopped glass fiber reinforced thermoplastic fiberglass FRTP as in a large class, it has been developed rapidly and widely.

How to Choose the Resin

Resin selection can vary from fabric compatibility, service conditions,fiberglass chopped strand mat and desired characteristics of the finished part. There are generally three types of thermosetting resin to consider when approaching your project: Epoxy, Vinyl Ester, and Polyester. Let’s take a look at each of the choices, their characteristics, and what they should be used for.

1. Epoxy Resin

For composite parts that demand the ultimate strength, fabricators will use an Epoxy Resin. In addition to increased strength properties, epoxies also generally outperform polyester and vinyl ester for dimensional stability and increased bonding with other materials.

Pros: 

Epoxy Resin, High Strength Properties, Can be used in vacuum infusion applications, Easy to handle, Medium viscosity

Cons: 

Cannot be used with chopped strand mat

Not UV stable. This must be paired with a top coat when exposed to UV rays

2. Polyester Resins

Polyester Resins are the most widely used resins in the composites industry. Polyester Resins are less expensive, offer some corrosion resistance, and are more forgiving than epoxies. The majority of all fiberglass parts are constructed using Polyester Resins because they are easy to use, fast curing, and tolerant of temperature and catalyst extremes. Fibre Glast carries two different types of Polyester Resins, each with their own strengths and uses.

POLYESTER MOLDING RESIN

Pros:

Inexpensive, Easy to handle, Rapid wet-out, High thixotropic index (product won’t run on vertical surfaces)

Cons:

lower physical properties compared to more expensive resins

ISOPHTHALIC POLYESTER RESIN

Pros:

Dimensionally stable (minimal shrinkage), resists post cure problems, can be used in food contact applications

Cons:

Slightly more expensive than general purpose polyester resins

3. Vinyl Ester Resin

Vinyl Ester Resin is considered a hybrid of polyester and epoxy—meaning its handling characteristics, properties, and price generally fall just between the other two. It is important to note that, Of the three, vinyl ester resin will provide the highest corrosion resistance, temperature resistance and elongation (toughness.) Because of this, they are typically used when high durability, thermal stability, and corrosion resistance is needed.

Pros:

Vinyl Ester Resin, Extremely tough, corrosion resistant, heat resistant

Cons:

Short shelf life (3 months)

China southern airline developed new fiberglass for mainframe

The crispy and hard and difficult to handle glass fiber, in Nanjing University of Aeronautics and Astronautics the Professor Chen Zhaofeng laboratories, it becomes soft as silk. At the 12th session of the International Conference recently held vacuum insulation material on a new type of insulation material "ultrafine aircraft-grade wool," not only make thick refrigerator door thickness reduced by half, it will be used on large aircraft, make saving fuel, noise insulation.

Chen Zhaofeng group to improve the glass fiber components and nano-inorganic particles as raw material, the patented technology to synthesize core vacuum insulation panel has a micro structure imitation nest. It not only can be used to "big up" large aircraft may also be used for living in common refrigerators, vending machines, buildings.

According to reports, to measure the performance of insulation materials, mainly to see the thermal conductivity, the lower the coefficient, the better the insulation. The thermal conductivity of air is 0.026W / mK, and this "aircraft-grade superfine wool," the thermal conductivity of 0.0015W / mK, air 1/20. This material is one cubic meter only 5 kg weight, while one cubic meter of traditional materials weighing more than 100 kg. At the same time, fiberglass chopped strand mat the fiber is only 3-5 microns in diameter, can greatly reduce the required thickness of the object "insulation." To apply in the refrigerator vacuum insulation panels, for example, the thickness of only 5 mm, 50 mm insulation effect is equivalent to traditional foam board, so that the refrigerator door is thinner, larger internal storage space. In the Nordic countries, the heating energy consumption, the use of such a vacuum insulation panel, can increase 10 percent of indoor area.

    Chen Zhaofeng said that they had successfully won made large aircraft project C919 insulation materials, its insulation performance par with the highest international standards, noise performance than the most advanced Boeing standards but also nearly 10 percent higher. Future, this aircraft-grade glass wool will be posted on the C919 cabin interior, played the role of noise insulation.

A Simple Female Mold Construction with Fiberglass

Composite materials offer ability to be molded to complex shapes is perhaps the most popular. When a shape needs to be reproduced numerous times, it is most efficient to build a tool or mold within which the part can be fabricated. Molded parts emerge perfectly shaped every time and require little post-finishing work.

Molding or “stamping” has been used for years to shape metal products like car bodies, home appliances, and industrial fixtures. Metal stamping dies are cumbersome and cost thousands of dollars to produce. Only large companies can afford to build, operate, fiberglass chopped strand mat store, or even move these tools. Composite materials offer a cost effective way for anyone to make even large production runs of identical plastic parts in molds they can produce themselves.

Female molds or cavity molds offer numerous advantages for medium to large production runs. Finishing time is significantly reduced because every part emerges with a smooth outer surface.

2015 International Boat Manufacturer Exhibition briefing

2015 International Boat manufacturers exhibition was held in Louisville, Kentucky, September 14 to 16. The exhibition attracted 4700 visitors and 545 exhibitors, including 110 new exhibitors.

US composite fabric company demonstrated a new hybrid fabric, not only toughness, but also a truly unique aesthetic.

Most board is provided with four and biaxial non-crimped fabric, but the company's 4 '× 8' and 5 '× 10' repression suitable for a wide range of materials, depending on customer demand for weight and labor-saving . Famous pirate yacht manufacturers in all of its fiberglass chopped strand mat boats from the use of lightweight composite panels of mahogany, reduce weight and improve performance.

Redwood's carbon fiber and mixed appearance prefabricated composite sandwich panels (left). Viking Yacht uses a variety of wood composite panels in pirate bulkhead 92 (right) to reduce weight and improve performance.

The new high temperature resin

CRG company has developed a new high temperature resin (service temperature is 300-450 ℃) with ultra-low flammability, heat release and smoke release, similar to the workability and cost of epoxy resin. In addition, it can be curable into a thermoplastic state at temperatures below 110 ℃,  when the temperature is higher than 110 ℃ it will crosslinking. it can be converted into an almost pure carbon material at higher temperatures.

MG resin combine with fiber reinforcement using conventional processing technology to provide for low-cost, high-temperature structural composites potential. Water is the only volatile generation thing, it does need to be managed porosity, polymer analogous condensation reaction, such as phenolic resins and polyimides. However, preliminary tests MG resin composites showed lower amplitude compared to the heat release phenolic resin.

MG1000 test sample produced by glass fiber and carbon fiber fabrics and carbon fiber mat and hand lay-up by vacuum injection. Carbon fiber panels and carbon mat plate is autoclave at 200-250 ℃ and 2 hours post-curing. Fiberglass chopped strand mat  sample cured in an oven at 250 ℃. MG3000 test sample was prepared in a similar manner. Breadboard use abrasive fibers and resin production, and strive to explore low-density material ablation and thermal protection systems for (TPS) for the potential use spacecraft. Although the polymer formulation, processing and curing cycle to continue to decrease further optimized porosity, overall, the resulting composite exhibits good.

The World’s Largest Fiberglass Rotor Blade

Siemens not only has built a record breaking rotor, but also have the world’s largest rotor blade for wind turbines, and it is also the world’s largest fiberglass component to ever be cast in one piece. The giant, 75 meter (246 ft) long rotor blades will be installed in an offshore prototype wind turbine in Denmark later this year (2012). Called the Quantum Blade B75, this rotor is almost the length of an Airbus A380.

Record-Breaking rotor: World’s largest rotor blade

With a length of 75 meters, Siemens has built the world’s largest rotor blades for wind turbines. The giant components made of fiber glass will be used by Siemens’ new offshore wind turbine generation with a capacity of 6 megawatts (MW). They will be installed on the first prototype of Siemens’ 6-MW offshore wind turbine with the 154-meter-rotor, which will be erected this summer in Denmark’s Østerild. Each rotor has a diameter of 154 meters covering 18,600 square meters, which is the size of two and fiberglass chopped strand mat a half soccer fields. The tips of the blades move at up to 80 meters per second, or 290 kilometers per hour. The huge rotor was made possible by special technologies that enable Siemens to make extremely strong yet lightweight structures.

One Giant Fiberglass Coffee Cup

Sign Effectz designed, built, and installed a giant coffee cup sign for their client, Stone Creek Coffee in Downtown Milwaukee. This 8’ diameter, fiberglass-skinned cup now looks down on the streets of downtown Milwaukee from its perch atop Stone Creek Coffee’s factory. This fiberglass coffee cup was constructed with an aluminum ribbed substructure, filled, then lined with fiberglass to add strength and smoothness.

The design of the composite skin was simple: it is similar to the hull of a boat, which consists of structural fibers laminated together with a bonding resin. Because of the versatility of fiber selections, we could make it as strong as needed.

There is a wide range of materials when it comes to structural fibers and bonding resins. The mixture of the two, as well as the layup method used,fiberglass chopped strand mat gave us the level of structural stability required. It also impacts the cost as there is a direct proportion between strength and cost. So they chose fiberglass.

The use of Glass fiber chopped strand mat machine

What is the use of glass fiber chopped machine? Obviously, that is used to cut glass fiber chopped strand mat, which regardless of alkali glass fiber chopped strand mat or high alkali or E-glass, all of them can be cut. But you understand the performance of the chopped machine? Do you know what position play what role?

Fiberglass chopped strand mat suction pressure molding machine functional applications of each system there is often a puzzling question: Why have said the same glass fiber chopped strand mat forming machines, The difference in price from more than ten thousand yuan to have a hundred thousand, the performance difference between the manufacturer's business profits or equipment?

The answer is the latter: the performance of the device! The market has not only the suction pressure plastic machine, specifically. There is only the pressure of the press do not smoke, then there is one of the suction pressure suction pressure molding machine, Nanjing Shakespeare Company has launched a fourth set of suction, pressure, blowing one of the glass fiber chopped strand mat suction pressure blow molding machine.

Due to the different types of equipment structure, function much difference, of course, manufacturing equipment cost is also different. But they also use thermoformed principle, such as: Beijing × company launched series. However, the series device has only one vacuum system, so only a plastic function, glass fiber chopped strand mat products suppliers, the use of such devices, create the same shapes, colors and diverse products, but products concave corners can not obvious, and thus It is because of the structure of a single face of such equipment, low interest rates, dysfunction and other reasons, the market price is only about $ 20,000 (in Face 1.5m2.6m example) As the function of this device is that only a simple pressure, structure , low interest rates, while the Guangdong market Another device commonly used is not only the suction pressure presses. So early in the glass fiber chopped strand mat products industry development, comprehensive widely used everywhere, in fact it is only limited to wood processing industry commonly simple press it. However, smoking is not only due to pressure on its plastic machine function was different, so these devices can be made only angular products, where the edges and corners obvious, only use plastic machine finished products, such equipment often inaccessible !

Fiberglass Lifeguard Towers in Palm Beach County

The current wooden towers of Palm Beach County have been moved several times due to erosion of the beach, nourishment (when sand is brought in to restore the beach) and storms. The 25-year-old towers have suffered damage during the moves as well. So the county is considering replacing its old wooden stands with more durable and portable fiberglass lifeguard towers.

Fiberglass installation at about $35,000 apiece with $25,000 pilings, would be anchored in the bedrock, and would be easier and quicker to move when necessary. The APEX Tower, the model under consideration in Palm Beach, is smaller and more weather-resistant than other versions, with less deck area and fiberglass chopped strand mat overhangs to avoid lift from wind. Within the fiberglass lifeguard towers, two lifeguards would have a 180° view while safe from the elements. Shutters help protect the stand from vandalism and weather.

Fiberglass can be molded to be stiffer and and more resilient than wood at a lower weight, which makes it a very popular material for boat hull construction. Resin reinforcements, such as the polyester used for these towers, may be very resilient to weathering from ultraviolet light and corrosion from salt and water.

Because the fiberglass lifeguard towers are anchored to the bedrock and sit on skids, they can be placed on eroding beaches, or farther back. Erosion in Jupiter, Fla., in Palm Beach County, has carved 12-foot drop-offs in areas and has eliminated some beaches.

Fiberglass Components on Bridges

Structural engineers have been using fiberglass composites for bridge construction and repair for almost 20 years now. But the popularity of this practice has grown exponentially worldwide for a number of reasons.

These bridge components are extremely lightweight compared to other materials, like concrete. They can be prefabricated, then transported to the installation site. They can be erected on prepared foundations in a matter of hours, causing minimal disruption to traffic.

Low Weight and High Strength. Composites deliver strength to support the job, with low weight that translates to low transportation and erection costs, smaller foundations, and easier handling.

Low Maintenance and Long Life. Fiberglass composites are corrosion and weather resistant, standing up to the elements, fiberglass chopped strand mat like sunlight, rain, and extreme temperatures. Thus, maintenance costs are much lower over time.

Two Interesting Fiberglass Applications

1. Gato del Sol.

While it might sound like an exotic beach location, this is actually the name of the solar-powered car designed by the University of Kentucky Solar Car Team that really puts fiberglass and the practices of composite lamination to work. The team has competed with some version of Gato in races around the country for about a decade. These cars are powered by solar energy, fiberglass chopped strand mat and engineered meticulously. Thus aerodynamics and weight are critical in design, which is where fiberglass comes into play. Gato V is set to be road-ready this season. 

2. Salem Sue.

Made from fiberglass and touted to be “the world’s largest Holstein cow,” Salem Sue stands 38 feet high and 50 feet long, along Interstate 94 in New Salem, North Dakota. She was built largely from fiberglass in 1974 to honor the region’s dairy industry—and who doesn’t love giant fiberglass cattle? Stop by and get your photo with Sue.

Evonik launched a new glass fiber composite material

Recently Evonik has developed a VESTAMID HTplus M1035 P1, which is glass fiber-reinforced molding compound based on polyphthalamide dimethylformamide (PPA).

The company said the material is designed for use in the automotive industry to dynamically strengthen the housing assembly. It has the strength to withstand high burst pressure and alternating stress and anti-corrosive media good chemical resistance.

The new PPA level in terms of impact strength also achieved good results.

With the VESTAMID HTplus series of products development, it will replace the traditional metal applications. It is a semi-crystalline, fiberglass chopped strand mat polyphthalamide-based material which is resistant to high temperatures and chemicals.

Comparison between Fiberglass and Carbon Fiber (2)

Fiber fabric and the resin are the general two parts of composite materials, with the physical properties of the material being fiber dominant. What that means is, when the resin and fiber are combined, their performance will primarily depend upon the fiber used. Test data shows that the fiber reinforcement is the component that will carry the majority of the load within the composite. So what does that mean? Well. Simply put, what fabric you choose is going to matter.

The two most common types of fabric in the industry are fiberglass, and carbon fiber. Both have a wide assortment of usages, and are extremely versatile. How do the two weigh up against each other? While comparing the two, Keep in mind, both fiberglass and carbon fiber will vary depending on the fabric you choose. A lightweight 2 oz Fiberglass Fabric will not have the durability of the more structural 10 oz Fiberglass Fabric. Additionally, the weave of the fabric and the resin used will have a large impact on the strength and properties of your composite product. 

Fiberglass

Fiberglass is the most widely used fiber in the industry, and with good reason. Fiberglass chopped strand mat is versatile, easy to handle and relatively inexpensive compared to its counterparts. Fiberglass is perfect for every day projects that are not expected to need the added strength and durability of higher priced fabrics. Fiberglass is compatible with most resins, and comes in a multitude of patterns and weaves.

Carbon Fiber

Carbon Fiber is far and away the premium end for composite materials. With excellent ultimate tensile strength, along with the greatest compressive, flexural, and bend strength in the industry, carbon fiber is the go to on projects that need to be built tough. Carbon Fiber is ideal for projects that need that added “umph” of strength, so long as you can handle the corresponding “umph” to your wallet. With its distinctive design look, carbon fiber is a popular choice in a multitude of industries, including the automotive and aerospace sectors.

AVIC will develop light sport aircraft in fiberglass composite materials

October 3, 2015, AVIC held light sport aircraft new product launches in Jingmen love to fly off the flight of the General Assembly, the site released by AVIC affiliation AVIC special flight / aircraft fly through Institute (hereinafter referred to as: special the fly / Institute) designed light sport aircraft - "lead goose" AG50 light sport aircraft.

It is understood, "lead goose" AG50 light sport aircraft invested by AVIC, and single-seat special flight / Institute for independent research and development, high-wing, amphibious light sport aircraft, machine mainly made of glass fiber composite materials As the structure of the main material, ensure that the aircraft structure light weight, high strength, good safety, low cost, beautiful appearance. Aircraft with full mold production, flight performance par with Europe-based products. The series of land-based aircraft landing gear systems using high-strength spring steel and low pressure aviation tire, brake system components, safe and efficient, in roads, airstrips, grassland and riverside landing. Water aircraft all fiberglass chopped strand mat double pontoon structure, can take off and land on water surface wave height 0.3 m; the body has a pontoon and landing gear interfaces, floats and landing gear modular design, enabling water type and land type fast conversion. Folding wings, bay be realized cars and easy road transport, garage parking. Meanwhile, AG50 aircraft has a very excellent cruising performance and mobility, energy security at a very low speed take-off, landing, and manipulate simple. In addition, optional Airframe Parachute, maximize the protection of aircraft take personal security personnel.

Glass Fiber VS Carbon Fiber

Glass Fiber and carbon fiber are widely used in composites these years. So what’s the difference between them?

WEIGHT

Glass Fiber Carbon Fiber Comparison So how do the two match up, against each other? For one,  Glass Fiber fabric is much less efficient in it’s density, when compared to it’s composite counterparts. While Glass Fiber is still significantly lighter than conventional materials (wood, steel, etc) for it’s given strength, on weight critical projects carbon fiber will preform much better as a reinforcement.

STRENGTH AND DURABILITY

Similarly, carbon fiber will outperform Glass Fiber in it’s tensile strength (the amount of force that needs to be placed on a fiber in order to pull it apart) and compressive strength (the amount of force that presses down on a fiber). However, Fiberglass chopped strand mat or Glass Fiber is more “durable” in that you can bring Glass Fiber near to it’s breaking point repeatedly without much cause for concern, unlike carbon fiber.

MODE OF FAILURE

Additionally, once carbon fiber reaches it’s breaking point, the mode of failure is catastrophic (it will fracture/shatter the piece.) Glass Fiber on the other hand, will develop cracks or deform before it breaks.

COST

Unfortunately, due to the nature of carbon fibers, it is much more expensive compared to its counterparts. So if your project isn’t weight dependent, and won’t need the excellent strength that comes from carbon fiber, Glass Fiber is a great choice to go with.

The different glass type in composite materials

alkali-free or E glass, it’s named by its chemical composition, which is an excellent electrical insulator, which is particularly suitable for application to the desired radio signal, better transparency areas, such as aircraft radomes, antennas and printed circuit board. At the same time, it is also the most economical glass fiber composite materials to meet at a relatively low cost in many applications, which will provide enough performance requirements strength. It has become the standard form of glass fiber, accounting for more than 90% glass fiber reinforced materials. At least 50% of E- glass fiber is made of silica oxide;fiberglass chopped strand mat the rest consisting of aluminum, boron, calcium and / or other compounds, also include limestone, fluorite, boric oxide and clay.

When you need more strength, high-strength glass become an option, it was first developed in the 1960s and used for military applications. There are several high-strength glass - S glass in the United States, R- glass in Europe, and T glass in Japan, the strand tensile strength is about 700 ksi, it has a high tensile modulus of 14 Msi. The amount of silica aluminum oxide and magnesium oxide in S- glass has significantly more than E glass, it is stronger 40-70% than E glass.

When the temperature is up to 540℃, the strength of E glass and S glass will lose a half. Although this two types of fibers in this elevated temperature range still showed unusual strength. Manufacturers are constantly adjusted S glass formulations. The new S-3 UHM (ultra-high modulus) glass, for example, AGY (Aiken, SC, USA) launched a tensile modulus of the new S-3 glass has 14,359 in 2012 - higher than the S- glass and 40% higher than E glass - due to improved manufacturing and proprietary additives and melt chemistry of the fiber.

Fiberglass chopped strand mat rolling notes

The rolling-up of the  fiberglass chopped strand mat is the last step of the production. Chopped strand mat will according to customer requirements where the number of meters cut ,wrapped in the paper tube, put endometrial bags, storage crates! It looks like this is a very simple process, but the rolling is the final hurdle for the quality of the finished chopped strand mat. Do you know the rolling precautions?

First, the product may not appear close black silk, holes, wet, fold and so on, these products are substandard products.

Second, this section can be seen best product uniformity, have significantly uneven product, there are holes product is substandard products, do not accept.

Third, when rolling a good roll, we should roll-up the next roller, then deal with the before products.

Fourth, the product must be put on endometrial bags, weighed, and after packing to meet the requirements, if do not meet the requirements of the situation should be labeled.

Fifth, when use the winding road we must use the jog manner, to avoid accidents.

Seemingly simple rolling precautions more, only to seemingly simple things to the extreme that we can truly do the rolling work well!

Fiberglass in composite materials

The main structural characteristics of the composite material reinforced by fibers derived. In composite materials, fibers, through the matrix resin, which is held in place, contributed to high tensile strength, and enhance the performance characteristics of the final portion, such as strength and stiffness while minimizing the weight of the finished component.

Fiber characteristics determined by the fiber manufacturing process, the chemical composition of the fibers in the resin matrix of the adhesive fiber with the coating chemical and further adapted to protect it during processing.

Fiber glass

All fibers used in the composites industry in the vast majority are glass fibers. Fiberglass chopped strand mat is the oldest, by far, the majority of end-market applications for the most common reinforcing member (aerospace industry is a notable exception) to replace heavier metal parts. By weight of glass fibers exceeds the second most common reinforcement, carbon fibers, and not stiff, but more resistant to impact, and the elongation to break greater. It depends on the level of the type of glass, filament diameter, chemical and fiber in the form of coatings, it can reach a wide range of features and performance.

In glass fiber production, molten material, and drawn into fine and highly abrasive filaments, a diameter in the range of 3.5 to 24 microns. Silica is the initial ingredients, typically accounting for more than 50% by weight of glass fiber. Metal oxides and other ingredients added to the silica and different processing methods can be customized fiber for specific applications.

Glass supply into bundles called shares. An continuous glass collection. Generally refers to an untwisted roving wire, packaging, such as in a large spool. Single-end roving by a continuous length, a plurality of strands of glass fiber bundles composed. Roving contain lengthy, but not completely continuous strand, which add or delete staggered winding process. Yarn is formed by a set of strands twisted together.

Tips for using fibers when making GFRC

Don’t think making GFRC is as simple as just adding some fibers to your concrete mix design. There are many important considerations to remember. Here are a few:

Amount of Fiber Present– GFRC relies on a high load of glass fibers. Without sufficient fiber the concrete will be unable to resist cracking and breakage when faced with a high tensile load. Fiber content varies, but is at least 3% of the total mix weight. Some mixes go as high as 10% fiber content. The more fiber present the stronger the GFRC, fiberglass chopped strand mat but increased fiber does lead to decreased workability and even to compromised compaction.

However, decreased fiber leads to the worse problem of less strength. Some concrete countertop teachers recommend only 2% fibers. I’m not sure what the motivation behind this is, but 2% is not sufficient. 3% is the minimum.

Orientation of Fibers– Orientation of the fibers in the mix is also important. Truly random fiber orientation means more fiber is needed since many of the fibers will be pointing in the wrong direction. See below for

Some concrete countertop teachers recommend creating a fluid backer mix and pouring it into the forms, effectively an “SCC” backer mix. This should not be done, as it results in random fiber orientation. See below and read this article for more information about why this is problematic.

Method of Reinforcement Used– There are three different levels of reinforcement used in general concrete and GFRC. Each type carries different benefits.

The Essential Component of GFRC Concrete-Glass Fiber

You are surely understand the importance of glass fibers in GFRC when think about the name for a minute.  Glass fiber reinforced concrete – without the fibers all you have is concrete. These alkali resistant glass fibers give GFRC its strength and make it an ideal choice for a variety of applications including concrete countertops.

According to Wikipedia.com, “glass fiber reinforced composite materials consist of high strength glass fiber embedded in a cementitious matrix. In this form, both fibers and matrix retain their physical and chemical identities, yet they produce a combination of properties that can not be achieved with either of the components acting alone. In general fibers are the principal load-carrying members, while the surrounding matrix keeps them in the desired locations and orientation, acting as a load transfer medium between them, and protects them from environmental damage.”

GFRC utilizes both concrete and strong AR glass fibers. Both possess benefits on their own, but when combined they become something amazing.

The retardant fiberglass chopped strand mat

Fiberglass chopped strand mat attachment rate generally around four percent, from that point, chopped strand mat itself has a certain degree of flame effect. However, as some aspects, the conventional chopped strand mat is not required by part of the enterprise for retardant glass fiber mat, so retardant glass fiber mat has been the object of study of the production enterprises! British glass fiber products manufacturer Scott & Fyfe company first completed this study!

Scott & Fyfe's products are Polymat FR, which is designed uses a sandwich of chopped glass fiber mat for the RTM (resin transfer molding), the core material is 100% glass fiber, sandwiched between two layers of chopped strand mat. the fiberglass weight percentage in FRP products up to 40 percent,  forming a high strength products.

According to reports, Polymat FR products will be aimed at the highest level of fire performance applications, such as the interior components for rail vehicles which meet EN45545 standard. This design goal also need flow of resin performance with efficient and fast. So that improving production efficiency when using high glass content. Early reaction from the market is very favorable, the company will feel excited that this fireproof composites product will have a place in this market.

The prevention method for hand-lay FRP products bleaching and yellowing

During Using hand-lay FRP product, the surface severe frost or yellowing. Causes and prevention measures are as follows:

The main reason and solution for bleaching：

1, the gel coat resin is not completely cured, appropriate changes in the ratio of hardener systems and usage.

2, pigment or filler improper selection or excessive amount, must strictly control the dosage.

3, resin formulations wrong, does not apply to the conditions of use, it must be properly selected resin formulations.

4, resin or fibers mixed with water, too much humidity operating environment, must overcome aerodynamic influence of moisture or wet.

Yellowing causes and solutions

1, the speed of the working chamber is too large, or reinforcing material too dry, the working environment should ensure that the raw materials with dry and low humidity;

2, resin wrong or incomplete curing, stability of the resin should be used to make products entirely cured before use;

3, Using benzoyl peroxide and amine accelerators easy to turn yellow, and if use too much peroxide methyl ethyl ketone and colorless accelerators it will be better.

How to deal with the fiberglass chopped strand mat uneven

Fiberglass chopped strand mat uneven is caused by production process winder, sedimentation control dispersion process! Chopped strand mat production enterprises more or less there will be unevenness in the process! Analysis of this phenomenon for several reasons:

1, yarn, yarn quality is not optimistic. We purchased yarn with coarse strip, uneven thickness. Which belong to the reason of yarn production. In the case of uneven yarn, chopped settlement passes, the same unit area of the mat will be caused some holes and uneven.

2, winding, spooling to find the thread into the hole chopped machine, there are dozens of stocks debris to enter dozens of short-cut machine hole. Strictly, a short-cut machine hole into one yarn, but some shift workers lazy, several strands of thread yarn simultaneously into a cutting machines hole, resulting in some machines bore no yarn can enter, and some machine hole in too much yarn, settlement dispersed unevenly.

3, the construction environment temperature, humidity, low temperature, high humidity will also not conducive to the yarn filaments dispersed.

For the above two cases you can use the following three methods to resolve:

1, purchase good quality yarn for production, requiring uniform thickness, moderate stiffness of the yarn, the yarn evenly distributed convenient short-cut settlement process. The quality of the yarn can directly affect chopped strand mat uniformity and quality, so choose high-quality glass fiber yarn is a prerequisites condition for produce high-quality and evenly chopped strand mat.

2. Winding. the stringent requirements that one hole for one wave of yarn, which makes the cut yarn can uniformly settlement. This requires construction workers to strictly responsible for the operation, who can not have the phenomenon of sabotage lazy. Should strict accordance with the requirements of the construction product uniformity will be greatly improved.

3, the above two methods strictly enforced if there will be uneven, you can adjust the throttle, which requires resourcefulness, where thick adjust where, once even we don’t need frequent changes in throttle.

4, environmental temperature and humidity, according to the actual situation to control, try to avoid the environmental and humidity affect the chopped strand mat production!

Use GRP for Antwerp Zoo Aquarium’s Renovation

Antwerp Zoo has used these materials for making moulds and grids as part of the renovation work carried out in the aquarium. Thanks to the outstanding properties of glass fibre reinforced plastics they can be used for a wide range of applications.

Glass fibre reinforced plastics (FRP) are composite materials made from glass fibres and resin, where the (glass) fibres give the material its strength and the resin provides resistance to chemicals. Moreover, this combination of materials results in a strong, lightweight material, which is suitable for a wide range of applications, also in salt water environments.

The Antwerp Zoo aquarium is over a hundred years old, making it one of the oldest in Europe. Naturally it has been renovated a number of times, including recently. The time taken to complete the renovation was three years. Glass fibre reinforced plastic played a significant role in this extensive project.

The new, large tank at the rear of the building is the culmination of the entire renovation project and was designed to become the main attraction and crowd-puller for visitors to the aquarium. The tank is 12 metres wide, 6 metres long and 4.5 metres in height. In order to accurately replicate the biotope of the fish, the initial idea was to create a coral reef using blocks of moonstone. But because this was going to weigh approximately 35,000 kilograms, an alternative had to be found. Glass fibre reinforced plastic provided the solution.

It was decided to make the ground structure from plastic with glass fibre reinforced plastic grids fitted on top, over which coral moonstones could be laid. This resulted in the total weight of the structure being reduced to 10,000 kilograms. The second important reason for using a glass fibre reinforced plastic structure was that the tank had to be filled with salt water. This ruled out using metal components. 

Therefore the glass fibre reinforced plastic structures provided the ideal solution. The entire FRP structure is kept in place with plastic anchors and bolts. The grids are fixed to the load-bearing structure by way of a nylon rope.

For the very same reasons, glass fibre reinforced plastic has been used for parts of the aquarium not visible to the visitors. All the tank covers in the aquarium building are also made from FRP.
