The baseline carbon: 5.7 oz/yd² woven from 3K tow in a plain over-under weave, 50 in wide, first quality. Plain weave holds its shape on the bench and on the part, which is why it is the pick for flat panels, tubes and any skin where a uniform, tight pattern matters more than drape over a compound curve.

5.7 oz/yd², 3K tow, 0/90 plain weave
50 in wide, first quality (no seconds, no off-spec)
Runs best in epoxy for cosmetic and structural carbon work
Holds its weave when handled, so the pattern stays straight on the part
Cut to 1, 3 and 10 yards, or take the full roll (100 yards)

If the part has deep curves, the 5.7 oz 2x2 twill in the same weight drapes better with the same fiber. For a bolder pattern, go up to the 8.3 oz 4x4 twill.

What To Expect When You Order Fabric Rolls

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 fabric?

Carbon fiber has a tensile strength around 500,000 psi and is roughly five times stronger than steel by weight, which is why it is used where stiffness and low weight both matter. Real-world laminate strength depends on resin, fiber orientation, and layup quality, so a strong carbon panel comes from good wet-out and proper ply orientation, not the fabric alone.
