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.
