Carbon Fiber Bidirectional (BD) 12K Fabric
Heavy-Duty 12K Bidirectional Carbon Fiber Fabric for Structural Composite Reinforcement & Thick Laminates
Carbon Fiber Bidirectional (BD) 12K Fabric is a high-strength woven reinforcement material manufactured from 12,000-filament (12K) carbon fiber tows, arranged in a balanced bidirectional (0° / 90°) construction to provide uniform strength and stiffness in both warp and weft directions.
This fabric is engineered for heavy structural composite laminates where high load-bearing strength, fast thickness build-up, and cost-effective reinforcement are required. Compared to 3K and 6K fabrics, 12K bidirectional carbon fabric enables faster lay-up, reduced ply count, and improved production efficiency, making it ideal for marine structures, industrial composite panels, automotive reinforcement parts, wind energy components, and tooling applications.
Key Performance Advantages
- Tow Size: 12K (12,000 filaments per tow)
- Bidirectional Reinforcement (0° / 90°)
- Balanced Strength in Warp & Weft Directions
- High Tensile Strength & Stiffness
- Efficient Laminate Thickness Build-Up (Reduced Ply Count)
- Faster Lay-Up for Industrial Production
- Excellent Strength-to-Weight Ratio
- Good Resin Wet-Out & Processing Stability
- Excellent Fatigue & Chemical Resistance
- Electrically Conductive (EMI Shielding Capable)
This fabric is ideal for manufacturers seeking heavy reinforcement with stable processing and consistent mechanical performance.
