Carbon Fiber Fabric 12K – 400 GSM Twill Weave
Heavyweight 12K Twill Weave Carbon Fiber Fabric for Structural & Curved Composite Laminates
Carbon Fiber Fabric 12K – 400 GSM Twill Weave is a heavy-duty woven reinforcement material manufactured from 12,000-filament (12K) carbon fiber tows, interlaced in a twill weave pattern (commonly 2×2).
With an areal weight of 400 GSM, this fabric is engineered for high-strength structural composite laminates requiring greater thickness build-up, excellent stiffness, and improved drapability compared to plain weave. The twill weave construction offers better mold conformity, easier handling, and smoother laminate appearance, making it ideal for curved structural parts, marine reinforcement, industrial composite panels, automotive reinforcement components, and wind energy structures.
Compared to lighter fabrics, 12K 400 GSM twill carbon fabric builds laminate thickness faster with fewer layers, improving production efficiency for large composite parts.
Key Performance Advantages
- Tow Size: 12K (12,000 filaments per tow)
- Areal Weight: 400 GSM
- Twill Weave (2×2) Construction
- Improved Drapability vs Plain Weave
- High Tensile Strength & Stiffness
- Efficient Laminate Thickness Build-Up (Reduced Ply Count)
- Faster Lay-Up for Industrial Production
- Balanced Bidirectional Reinforcement (0° / 90°)
- Good Resin Flow & Wet-Out
- Excellent Fatigue & Chemical Resistance
- Electrically Conductive (EMI Shielding Capable)
This fabric is ideal for manufacturers needing heavy reinforcement with better processing on curved molds.
Fabric Construction Details
- Fiber Type: PAN-based Carbon Fiber
- Tow Size: 12K
- Weave Style: Twill Weave (2×2)
