Stitched carbon at plus and minus 45 degrees, 12 oz/yd² on 12K tow, 50 in wide. The double bias is the point: fibers running off-axis take torsion and shear directly instead of relying on two rotated plies of woven cloth, so a hull panel, a tube or a shaft gets its twist stiffness from one layer.

12 oz/yd² carbon, 12K tow, stitched biaxial at plus and minus 45 degrees
50 in wide, roll length 100 yards
Non-crimp construction, so the fiber stays straight and works at full strength
Plan roughly 1.39 oz of mixed resin per square foot at about a 1:1 resin to fabric ratio by weight
Runs in epoxy, polyester or vinyl ester
Cut to 1, 3 and 10 yards, or take the full roll

Stack it under a woven show ply when the part needs torsional stiffness but the outside has to look like twill.

What To Expect When You Order Fabric Rolls

What is biaxial carbon fiber fabric used for?

Biaxial carbon fiber fabric has two layers of fiber stitched at plus and minus 45 degrees, so it resists the twisting and shear loads that a single-direction weave cannot. The 45-degree orientation spreads force evenly, which makes it the go-to for torsional stiffness in masts, shafts, hulls, and high-stress panels. Wet it out with epoxy or vinyl ester resin and add layers to build the stiffness your structure needs.
