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.

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

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

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

The main difference is in the weave pattern and flexibility. Twill weave has a diagonal pattern (over 2, under 2), while plain weave has a tighter checkerboard pattern (over 1, under 1).

Use 2x2 twill when you're working with curved surfaces or want a sleek, visible finish. Use plain weave for flat surfaces, structural reinforcement, or areas that will be painted or hidden.

It’s commonly added to resin for strength and is also used in molded forged carbon parts.
