6K Carbon Fiber Fabric 4HS (Harness Satin) Weave

Premium 6K 4HS Carbon Fiber Fabric for Smooth Laminates, High Drapability & Structural Composite Reinforcement

6K Carbon Fiber Fabric 4HS (Harness Satin) Weave is a high-performance woven carbon fiber reinforcement fabric manufactured from 6,000 filament (6K) carbon fiber tows, woven in a premium 4 Harness Satin (4HS) weave structure.

The 4HS weave is widely preferred for applications requiring a balance of:

  • smooth surface finish
  • good drapability
  • stable handling during lay-up
  • strong structural reinforcement

Compared to plain weave fabrics, 6K 4HS carbon cloth offers improved mold conformity and reduced crimp, resulting in better laminate quality and improved mechanical efficiency. It is commonly used in automotive composite parts, marine laminates, aerospace secondary structures, industrial composite panels, and sporting goods reinforcement.

Key Features & Benefits

  • Tow Size: 6K (balanced tow for strength + good surface finish)
  • Weave Type: 4HS (4 Harness Satin / Harness Satin)
  • Smooth laminate surface finish compared to plain weave
  • Better drapability for curved parts and complex molds
  • Stable weave construction for easy cutting and lay-up
  • Reduced fiber crimp for improved load transfer
  • Excellent resin wet-out & consolidation
  • Suitable for vacuum infusion, vacuum bagging, RTM & prepreg
  • Compatible with epoxy, vinyl ester & polyester resin systems
  • Ideal for structural laminates + cosmetic visible carbon parts

What is 4HS (Harness Satin) Weave?

4HS (4 Harness Satin) is a satin weave pattern where carbon tows float over multiple yarns before interlacing. This creates:

  • smoother laminate surface
  • improved flexibility and drape
  • good handling stability
  • premium visible carbon appearance

4HS weave is often selected when buyers want a premium satin finish but still require easy lay-up and fabric stability.
