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.
