Carbon Fiber Bidirectional (BD) 6K Fabric
High-Strength 6K Bidirectional Carbon Fiber Fabric for Structural Composite Reinforcement
Carbon Fiber Bidirectional (BD) 6K Fabric is a heavy-duty woven reinforcement material manufactured from 6,000-filament (6K) carbon fiber tows, arranged in a balanced bidirectional (0° / 90°) construction to deliver uniform strength in both warp and weft directions.
6K bidirectional carbon fabric is widely used for structural composite laminates where high stiffness, efficient laminate build-up, and production productivity are key requirements. Compared to 3K fabrics, 6K carbon fabric provides higher thickness per ply, reduced ply count, and faster lay-up, making it ideal for marine structures, automotive reinforcement, industrial composite panels, and tooling applications.
Key Performance Advantages
- Tow Size: 6K (6,000 filaments per tow)
- Bidirectional Reinforcement (0° / 90°)
- Uniform Strength in Warp & Weft Directions
- High Tensile Strength & Stiffness
- Excellent Strength-to-Weight Ratio
- Efficient Laminate Thickness Build-Up (Reduced Ply Count)
- Faster Lay-Up for Industrial Production
- Good Resin Wet-Out & Processing Stability
- Excellent Fatigue & Chemical Resistance
- Electrically Conductive (EMI Shielding Capable)
This fabric is ideal for manufacturers requiring balanced structural reinforcement with high productivity.
