Carbon and Glass Fiber Prepregs Reinforce Composites Success

Prepregs are composite materials that have been pre-impregnated with a thermoplastic or thermoset resin, serving to reinforce the strength and performance capabilities of fibers in composites applications. Carbon fiber and glass fiber, or fiberglass, are among the most common advanced reinforcement materials used in prepregs together with the resin. Both carbon and glass fiber can be used with various composites manufacturing processes and offer high performance in a variety of extreme applications, such as in the aerospace, industrial, or military sectors.

Prepreg carbon fiber reinforcement is one of the most advanced products for making composite parts. With high-quality surface finish and low resin content, prepreg carbon fiber composites offer excellent structural performance. Additional benefits of carbon fiber composites are its strength, temperature and chemical resistance, lightweight, and flexibility.

Glass fiber is often impregnated with epoxy resin to form a prepreg. It offers the benefits of structural stability, lightweight, easy handling, and strength. For composites manufacturers, glass fiber is beneficial as an affordable prepreg composite fiber.

The power of prepregs

Carbon fiber and glass fiber prepregs offer the mentioned benefits due to their tightly controlled resin content. The resin impregnation process throughout the reinforcement is highly controlled to precisely achieve the desired fiber-to-resin ratio and ply thickness for a high strength-to-weight ratio and overall higher degree of quality control.

Prepregs are widely used because of their high control and accuracy in many composites manufacturing processes. High-performance industries can benefit from parts with high strength-to-weight ratio, controlled part thickness, and weight, repeatability cosmetic consistency and corrosion resistance.
