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.
