Carbon Fiber Fabric – 2×2 Twill Biaxial ±45/−45, 3k, 48"/121.92 cm, 5.7 oz (193 gsm) – Hexcel AS4C

This biaxial carbon fiber fabric is engineered for structural laminates that need balanced in-plane shear and torsional performance. Woven in a 2×2 twill and set at ±45/−45 degrees, it uses aerospace-grade Hexcel AS4C 3k fiber for a clean cosmetic finish and reliable mechanical properties. At 48" (121.92 cm) wide and 5.7 oz/193 gsm, it drapes easily, consolidates well under vacuum, and produces parts with a smooth, high-end appearance.

Why choose this ±45/−45 biaxial?

• Balanced torsion & shear: ±45 architecture efficiently carries in-plane shear loads, ideal for tubes, shells, skins, and closed sections.
• Premium fiber: Hexcel AS4C is a proven aerospace 640 ksi-class carbon for consistent strength and laminate quality.
• 2×2 twill face: excellent drape around complex shapes with an upscale, low-print cosmetic surface.
• Lightweight efficiency: 5.7 oz (193 gsm) weight helps you hit target mass while maintaining stiffness and strength.
• Process-friendly: compatible with epoxy, vinyl ester, and polyester systems; ideal for wet layup, vacuum bagging, and infusion.

Typical applications

• Motorsport panels, splitters, diffusers & bodywork
• UAV/Drone frames, aerospace fairings & radomes
• Bike & marine components, instrument enclosures
• Tubes, spars, torsion boxes, composite skins & sandwich laminates

Recommended resins

For best structural and cosmetic results use a high-quality epoxy. Polyester and vinyl ester may also be used for non-aerospace projects, tooling, and cosmetic skins.

Key specifications

Handling & notes

• Store clean and dry; keep covered between layup steps to prevent contamination.
• Handle with gloves and cut with sharp shears; stabilize edges with tack spray if needed.
• Consolidate under vacuum for optimal fiber volume and surface finish.
