Patented Bias Weave Fabrics
HexForce® bias weave fabrics
PATENTED SOLUTION TO OPTIMIZE
MATERIAL USAGE
Hexcel has developed a patented process to manufacture
continuous rolls of carbon fiber cloth that are woven such
as the warp and weft yarns are oriented at +/- 45 degrees
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 eg. Slit tape fed into a 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...
• Helicopters blades
• Engine nacelles
• Secondary structures
• Barrel sections of aircraft
PRODUCT RANGE
• Currently available from 193 to 285 3K HS and from 193 to 285 6K IM
• HexForce® PX (+/-45° plain weave)
• HexForce® CSX (+/-45° crow foot satin weave)
Produced with High Strength (HexTow®AS4) and Intermediate Modulus
(HexTow®IM7) fibers
Minimum master width available: 50” and 60”
Ideal for prepreg and RTM processing
