Chemical Resistant Carbon Fiber Tissue Veil Carbon Fiber Surface Mat For Automotive

Carbon Fiber Surface Mat is a non-woven carbon fiber material engineered from short-cut carbon fibers via wet-lay forming and vacuum consolidation. It features uniform fiber distribution, smooth surface texture, and exceptional permeability, making it ideal for enhancing composite materials.

• Lightweight: Density as low as 1.5-2.0 g/cm³, ideal for aerospace and automotive applications.
• High Strength-to-Weight Ratio: Tensile strength up to 4,800 MPa, outperforming traditional glass fiber.
• Electrical Conductivity: Surface resistivity <10 Ω, suitable for EMI shielding and electronic components.
• Chemical Resistance: Resists acids, alkalis, and solvents, ensuring durability in harsh environments.
• Applications: Automotive panels, aerospace interiors, electronic housings, wind turbine blades, and sports equipment.

1. Precursor Processing:
   • PAN-based carbon fiber precursor is stabilized at 200-300°C and carbonized at 1,000-3,000°C to achieve graphite-like structure.
2. Fiber Cutting & Dispersion:
   • Carbon fibers (6-7 µm diameter) are cut into 30-50 mm lengths and dispersed in water with eco-friendly binders.
3. Wet-Lay Forming:
   • Fibers are layered on a mesh conveyor, vacuum-assisted to remove air, and pressed into uniform mats (30-50 g/m²).
4. Surface Treatment:
   • Coated with sizing agents (e.g., silane) to enhance adhesion and UV resistance.
5. Quality Control:
   • ISO 9001-certified testing for tensile strength, surface resistivity, and thickness consistency.

• Handling:
  • Avoid sharp tools to prevent fiber breakage; wear PPE (gloves, goggles) during cutting.
• Resin Compatibility:
  • Ensure compatibility with epoxy, polyester, or vinyl ester resins for optimal bonding.
• Curing Conditions:
  • Maintain 120-150°C and 0.5-1.0 MPa pressure in autoclaves to eliminate voids.
• Storage:
  • Store in dry, ventilated areas; avoid humidity to prevent delamination.

• Body Panels: Lightweight panels for EVs (e.g., BMW i3) to reduce weight by 30-50%.
• Interior Trim: Noise-damping panels for luxury vehicles.

• Aircraft Interiors: Fire-resistant seat covers and overhead bins.
• Rocket Components: Lightweight fuel tanks and structural parts.

• EMI Shielding: Enclosures for circuit boards and sensors.
• Heat Sinks: Thermal management in smartphones and laptops.

• Turbine Blades: Reinforcement for leading edges to withstand high winds.

• Protective Gear: Helmets and cycling frames (e.g., Trek Emonda SLR).
