1K Carbon Fiber Fabric 4HS Weave

Premium 1K 4HS (4 Harness Satin) Carbon Fiber Fabric for Smooth Finish, High Drapability & Cosmetic Composites

1K Carbon Fiber Fabric 4HS Weave (also known as 1K 4 Harness Satin carbon cloth) is a premium woven reinforcement fabric made from 1,000 filament (1K) carbon fiber tows, woven in a 4HS satin weave pattern to deliver an excellent balance of surface smoothness, drapability, and fabric stability.

Compared to 1K plain weave carbon fabric, 4HS carbon fiber cloth offers:

  • Improved flexibility for curved parts
  • Smoother laminate finish
  • Better resin wet-out and consolidation

This makes it ideal for high-end visible carbon fiber products, including automotive interior trims, drone/UAV shells, motorsport cosmetic panels, consumer electronics covers, and premium composite laminates.

What is 4HS Weave Carbon Fiber Fabric?

4HS (4 Harness Satin) is a satin weave construction where carbon fiber tows float over multiple yarns before interlacing, creating:

  • Smoother surface than plain weave
  • Improved flexibility and mold conformity
  • Balanced weave stability for consistent lay-up

4HS is often selected when buyers want a premium surface finish but still require good fabric stability during handling.
