3K Carbon Fiber Fabric – 4HS (Harness Satin) Weave
Premium 4 Harness Satin (4HS) 3K Carbon Fiber Fabric for Superior Drapability & Smooth Cosmetic Finish
3K Carbon Fiber Fabric – 4HS (4 Harness Satin) Weave is a high-performance woven reinforcement fabric manufactured from 3,000-filament (3K) carbon fiber tows, arranged in a 4 Harness Satin weave structure.
The 4HS weave is specially designed to offer better drapability, reduced fiber crimp, improved resin flow, and a smoother laminate surface finish compared to plain weave fabrics. This makes it ideal for curved and complex composite parts, especially where both structural performance and premium visible carbon appearance are required.
3K 4HS carbon fabric is widely used for automotive cosmetic parts, aerospace secondary structures, marine laminates, sports goods, and high-end composite components.
Key Performance Advantages
- Tow Size: 3K (3,000 filaments per tow)
- Weave Style: 4 Harness Satin (4HS)
- Excellent Drapability for Curved & Complex Shapes
- Reduced Fiber Crimp for Improved Load Transfer
- High Strength-to-Weight Ratio
- Balanced Bidirectional Reinforcement (0° / 90°)
- Superior Resin Flow & Wet-Out (Infusion Friendly)
- Smooth Surface Finish & Reduced Print-Through
- Ideal for Cosmetic + Structural Applications
- Electrically Conductive (EMI Shielding Capable)
This fabric is ideal for manufacturers requiring premium appearance with reliable composite performance.
