Carbon Fiber Fabric 12K – 400 GSM Satin Weave
Heavyweight 12K Satin Weave Carbon Fiber Fabric for Superior Drapability & High-Strength Structural Laminates
Carbon Fiber Fabric 12K – 400 GSM Satin Weave is a premium woven reinforcement material manufactured from 12,000-filament (12K) carbon fiber tows, woven in a satin weave structure (commonly 4H / 5H satin) to provide excellent mold conformity, superior resin flow, and smooth laminate surface quality.
With an areal weight of 400 GSM, this fabric is designed for heavy structural composite laminates requiring high stiffness, strong load-bearing capacity, and efficient thickness build-up, while still offering better drapability than plain weave for curved and complex composite parts.
The satin weave structure reduces fiber crimp and enhances load transfer, producing high-performance laminates with reduced print-through and improved finish.
Key Performance Advantages
- Tow Size: 12K (12,000 filaments per tow)
- Areal Weight: 400 GSM
- Satin Weave Construction (4H / 5H Options)
- Superior Drapability for Curved & Complex Shapes
- Reduced Fiber Crimp for Improved Load Transfer
- High Tensile Strength & Stiffness
- Efficient Laminate Thickness Build-Up (Reduced Ply Count)
- Superior Resin Flow & Wet-Out (Infusion Friendly)
- Improved Surface Finish & Reduced Print-Through
- Excellent Fatigue & Chemical Resistance
- Electrically Conductive (EMI Shielding Capable)
This fabric is ideal for manufacturers requiring heavy reinforcement with better processing on complex molds.
Fabric Construction Details
- Fiber Type: PAN-based Carbon Fiber
- Tow Size: 12K
- Weave Style: Satin Weave (4 Harness / 5 Harness)
