Frequently Asked Questions

What is carbon fiber?

Carbon fiber is a high-strength, lightweight material made from thin strands of carbon. It’s used in aerospace, marine, automotive, sporting goods, and composite construction for its superior strength-to-weight ratio.

Can carbon fiber be used with epoxy resin?

Yes, epoxy resin is the most commonly used resin with carbon fiber, providing a strong, durable bond for structural and cosmetic applications.

How strong is carbon fiber?

Carbon fiber has a tensile strength of around 500,000 psi and is five times stronger than steel by weight.

How is carbon fiber different from fiberglass?

Carbon fiber is stiffer, stronger, and lighter than fiberglass, but also more expensive. It’s used when performance and weight savings are critical.
