12K 5HS Carbon Fiber Fabric
Heavy-Duty 12K 5HS (5 Harness Satin) Carbon Fiber Fabric for Structural Composites & Smooth Surface Laminates
12K 5HS Carbon Fiber Fabric (also called 12K 5 Harness Satin carbon cloth) is a high-performance woven carbon fiber reinforcement fabric manufactured from 12,000 filament (12K) carbon fiber tows, woven in a premium 5HS satin weave structure.
The 5HS weave offers a strong balance between excellent drapability, high fabric stability, smooth laminate surface finish, and high structural reinforcement. Compared to plain weave and twill weave carbon fabrics, 12K 5HS carbon fabric provides improved mold conformity and reduced crimp, helping achieve high-strength laminates with better surface finish. It is widely used in automotive structural components, marine reinforcement laminates, aerospace secondary structures, industrial composite panels, and high-performance sporting goods.
Key Features & Benefits
- Tow Size: 12K (heavy tow for strong reinforcement)
- Weave Type: 5HS (5 Harness Satin)
- High strength-to-weight ratio for structural composites
- Smooth surface finish compared to plain weave fabrics
- Better drapability than plain weave for curved molds
- Reduced fiber crimp for improved mechanical performance
- 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 surface layers
What is 5HS Carbon Fiber Fabric?
5HS (5 Harness Satin) is a satin weave construction where carbon fiber tows float over multiple yarns before interlacing.
- Improved flexibility and drape
- Smoother surface finish
- Better mold conformity
- Balanced fabric stability for lay-up
5HS weave is widely used in high-performance composites requiring both strength and premium laminate finish.
