Carbon Fiber Twill Fabric | Premium Composite Reinforcement For Demanding Applications
Carbon Fiber Twill Fabric is engineered for applications requiring a balance of strength, flexibility, and aesthetic appeal. Characterized by its 2x2 or 4x4 twill weave pattern, this material offers enhanced drapeability and resistance to fraying, making it ideal for curved or complex geometries. Key features include:
High Tensile Strength: Ranges from 3,000–5,000 MPa, making it suitable for structural components under heavy stress.
Lightweight: Density as low as 1.5–2.0 g/cm³, critical for aerospace and automotive industries.
Thermal Stability: Operates effectively up to 300°C without significant degradation.
Corrosion Resistance: Impervious to acids, alkalis, and moisture, ideal for marine and industrial applications.
Precursor Processing:
Polyacrylonitrile (PAN) fibers undergo stabilization (200–300°C) and carbonization (1,000–3,000°C) to form graphite-like structures.
Weaving:
Carbon filaments (5–25 µm diameter) are interlaced in a 2x2 or 4x4 twill pattern using automated looms to create a diagonal ribbed texture.
Resin Impregnation:
Fibers are coated with epoxy, polyester, or vinyl ester resin to enhance adhesion and durability.
Layer Consolidation:
Multiple twill layers are stacked and bonded using heat-resistant adhesives.
Curing:
Heat and pressure (120–150°C, 0.5–1.0 MPa) ensure full resin curing and void elimination.
Handling:
Wear PPE (gloves, goggles) to avoid fiber irritation; use sharp tools cautiously to prevent breakage.
Resin Compatibility:
Match fabric type (e.g., standard modulus vs. high modulus) with epoxy, polyester, or vinyl ester resins.
Curing Conditions:
Maintain 120–150°C and 0.5–1.0 MPa pressure during curing to eliminate voids.
Storage:
Store in dry, ventilated areas (humidity <60%); avoid prolonged UV exposure to prevent coating degradation.
