Carbon Fiber Fabric 12K – 400 GSM Plain Weave
Heavyweight 12K Plain Weave Carbon Fiber Fabric for High-Strength Structural Composite Laminates
Carbon Fiber Fabric 12K – 400 GSM Plain Weave is a heavy-duty woven reinforcement material produced from 12,000-filament (12K) carbon fiber tows, interlaced in a balanced plain weave (1×1) construction for excellent dimensional stability and controlled fiber alignment.
With an areal weight of 400 GSM, this fabric is designed for high-strength structural composite laminates requiring greater thickness build-up, superior stiffness, and efficient production. The plain weave architecture provides uniform bidirectional reinforcement (0°/90°), making it ideal for structural panels, marine laminates, industrial composite parts, automotive reinforcement, and composite tooling.
Compared to lighter carbon fabrics, 12K 400 GSM fabric builds laminate thickness faster with fewer layers, reducing labor cost and improving productivity for large-scale composite manufacturing.
Key Performance Advantages
- Tow Size: 12K (12,000 filaments per tow)
- Areal Weight: 400 GSM
- Plain Weave (1×1) Balanced Construction
- Uniform Bidirectional Strength (0° / 90°)
- High Tensile Strength & Stiffness
- Excellent Dimensional Stability & Fiber Control
- Efficient Laminate Thickness Build-Up (Reduced Ply Count)
- Stable Handling for Industrial Production
- Good Resin Wet-Out & Processing Stability
- Electrically Conductive (EMI Shielding Capable)
This fabric is ideal for manufacturers seeking heavy reinforcement with stable processing and predictable mechanical performance.
Fabric Construction Details
- Fiber Type: PAN-based Carbon Fiber
- Tow Size: 12K
