3K Carbon Fiber Fabric – 4HS Weave
Premium 4 Harness Satin (4HS) 3K Carbon Fiber Fabric for Superior Drapability & Surface Finish
3K Carbon Fiber Fabric – 4HS Weave is a high-performance woven reinforcement material manufactured from 3,000-filament (3K) carbon fiber tows, arranged in a 4 Harness Satin (4HS) weave pattern.
The 4HS weave offers excellent drapability, reduced fiber crimp, and a smooth, refined carbon fiber surface appearance, making it ideal for complex-shaped composite parts, visible carbon fiber components, and high-end structural applications where aesthetics and performance must coexist.
Compared to plain and twill weaves, 4HS satin weave provides superior mold conformity and resin flow, resulting in high-quality laminates with minimal print-through.
Key Performance Advantages
- Tow Size: 3K (3,000 filaments per tow)
- 4 Harness Satin (4HS) Weave Construction
- Exceptional Drapability for Complex & Curved Shapes
- Smooth, Premium Carbon Fiber Surface Finish
- Reduced Fiber Crimp for Improved Load Transfer
- Balanced Bidirectional Strength (0° / 90°)
- High Tensile Strength & Stiffness
- Excellent Resin Flow & Wet-Out
- Minimal Print-Through in Laminates
- Electrically Conductive (EMI Shielding Capable)
The 4HS weave combines structural performance with cosmetic excellence, making it a preferred choice for visible carbon applications.
