Frequently Asked Questions

What is FRP?

FRP stands for Fiber-Reinforced Polymer. It is a composite material made of a polymer matrix reinforced with fibers such as glass, carbon, or aramid, offering high strength-to-weight ratio and corrosion resistance.

Can I get custom sizes or specifications?

Yes, we offer customization for profiles, fabrics, and resins based on your technical requirements and application needs.

Do you offer samples?

Yes, we provide product samples upon request. Please contact us through the official website for sample inquiries.

What are the advantages of carbon fiber over fiberglass?

Carbon fiber offers higher stiffness, lower weight, and better fatigue resistance than fiberglass, making it ideal for high-performance applications in aerospace and motorsports.
