Carbon Fiber Bidirectional (BD) 3K Fabric
High-Performance 3K Bidirectional Carbon Fiber Fabric for Structural Composites & Premium Finish
Carbon Fiber Bidirectional (BD) 3K Fabric is a high-quality woven reinforcement material manufactured from 3,000-filament (3K) carbon fiber tows, arranged in a balanced bidirectional (0° / 90°) construction to provide uniform strength in both warp and weft directions.
3K bidirectional carbon fabric is one of the most widely used carbon reinforcements due to its ideal balance of strength, drapability, laminate performance, and cosmetic appearance. It is commonly selected for automotive parts, marine laminates, sports goods, aerospace secondary structures, and industrial composite panels.
Compared to 1K, 3K offers higher productivity and better thickness build-up, while still maintaining an excellent visible carbon fiber look.
Key Performance Advantages
- Tow Size: 3K (3,000 filaments per tow)
- Bidirectional Reinforcement (0° / 90°)
- Balanced Strength in Warp & Weft Directions
- Excellent Strength-to-Weight Ratio
- Good Drapability & Easy Handling
- High Tensile Strength & Stiffness
- Efficient Laminate Build-Up
- Good Resin Wet-Out & Processing Stability
- Electrically Conductive (EMI Shielding Capable)
- Suitable for Structural + Cosmetic Applications
This fabric is ideal for manufacturers needing strong laminates with consistent surface finish.
