Weight: 19.7 oz/yd² (668 g/m²)
Fiber Angle: 0°/90° (woven)
Widths: 50 in
Compatible Resins: Epoxy, Polyester, Vinyl Ester
Resin Needed: About 1.1 qt per yard, waste included
Ships: Rolled, never folded

This is the heaviest carbon fabric we stock: 19.7 oz per square yard on 12K tow in a 2x2 twill, 50 in wide, 1st quality. The large tow puts a lot of fiber down per ply, so you hit laminate thickness in fewer layers and burn less resin doing it. It is a structural fabric, not a show-surface fabric, and the big weave is harder to form than a light twill.

Where it goes: flat and gently curved structural parts, thick plate layups, high-strength panels.
Build rate: 0.030 in per ply, roughly three times what a 5.7 oz twill lays down.
Resin demand: roughly 50:50 resin to fiber by weight, about 2.29 oz per square foot.
Forming: the 12K tow resists tight radii; plan on flat or large-radius tooling.
Resin compatibility: epoxy, polyester and vinyl ester.

Cut it with sharp shears or a rotary cutter and tape both sides of the cut line. Heavy tow frays hard.

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 fabric is a reinforcement, not a finished structural part. The cured laminate strength and stiffness depend on the fiber, resin system, fiber volume, ply orientation, thickness and processing quality. This dry fabric does not have a single guaranteed laminate-strength rating. Use a validated laminate schedule for load-bearing parts.
