HexForce® Bias Weave Reinforcements

HexForce® Bias Weave fabrics Patented solution to optimize material usage
Hexcel has developed a patented process to manufacture continuous rolls of carbon fiber fabric in which the warp and weft yarns are oriented on the bias at +/- 45°.

Benefits:
Reduced prepreg waste (up to 60% saving)

Can be woven to desired width

Kitting waste from cutting of standard 0/90° to +/- 45° is eliminated

Reduced labor

Part production can be automated e.g. Slit tape fed into laminator

Pattern cutting and lay-up is simplified

Increased design allowables

Warp and weft properties are equal (unlike standard 0/90° weaves)

Warp and weft have equal crimp, so provide equal properties in the laminate

Elimination of splices

This continuous fabric provides constant thickness along the length of the part

Typical Applications
Ideal for high aspect ratio parts that need bias reinforcement:

Ribs, stringers, spars

Helicopter blades

Engine nacelles

Secondary structures

Barrel sections of aircraft
