Our 11 oz Unidirectional Carbon Fiber Tape is designed for maximum strength in a single direction. With fibers running parallel along the tape length, this material is ideal for structural reinforcement, stiffeners, spars, and load-bearing components where directional strength is critical.

Specs

Fiber	12K carbon, unidirectional (binder threads only, no crosswise fiber)
Weight	11 oz/yd² (373 gsm)
Thickness	approx 0.017 in (0.43 mm) per ply
Widths	1, 1.5, 2, 3, 4, 6, 8 and 12 in
Lengths	1, 3 and 10 yd cuts, 100 yd full roll
Resin	epoxy, polyester, vinyl ester

Pick the unidirectional tape when the load runs one way along the tape: spar and stringer caps, mast and boom stiffening, rudder and tiller reinforcement. Every fiber runs lengthwise, so one ply is stiffer along the run than either woven tape and has no strength across it. For a woven face or hoop strength on a tube, use the 5.7 oz 3K plain weave tape; for a heavy balanced band in both directions, the 12.3 oz 12K plain weave tape. Compare widths across the line in carbon fiber tape.

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.
