Carbon Fibre 12K 2x2 Twill

12K, 2 x 2 Twill Weave Carbon Fiber Fabric is a heavyweight structural carbon fiber fabric designed to build thickness and strength quickly in composite laminates. According to Fibre Glast, it uses 12K tow carbon fiber (12,000 filaments per bundle) in a 2x2 twill weave, giving it the classic carbon fiber appearance while maintaining good drape and structural performance. Key Specifications Weave: 2x2 Twill Tow Size: 12K warp and fill Weight: 19.8 oz/yd² (approximately 671 gsm) Thickness: 0.030 in (0.76 mm) Tensile Strength: 620-655 KSI Tensile Modulus: 33.1-34.4 MSI Color: Black Best Uses Structural composite panels Automotive and motorsport components Marine structures Tooling skins and molds Large flat or gently contoured parts where stiffness and strength are critical Advantages Builds laminate thickness rapidly, reducing the number of layers required. Excellent strength-to-weight ratio. Classic carbon fiber twill appearance. Economical for large structural laminates compared with stacking many lighter fabrics. Considerations Less conformable than lighter fabrics such as 3K twill. Not ideal for small, highly contoured parts. Edges tend to fray when cut, so edge tape or fray control is recommended.
