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.
