Carbon Fiber Surface Mat : Lightweight Conductive Solutions For Advanced Composites
Carbon Fiber Surface Mat is a non-woven carbon fiber-reinforced material engineered for enhancing surface quality and functional performance in composite applications. Composed of ultra-short carbon fibers (3–15 mm) uniformly distributed within a polymer matrix, it delivers exceptional mechanical strength, corrosion resistance, and electromagnetic shielding. Its unique architecture ensures seamless integration with resins, offering smooth surface finishes, reduced weight, and improved thermal stability. Ideal for aerospace, automotive, and electronics industries, this material balances lightweight construction with high durability.
Key Features:
Lightweight & High Strength: Density as low as 1.2 g/cm³ with tensile strength exceeding 3,000 MPa.
Electrical Conductivity: Surface resistivity <10 Ω, suitable for EMI shielding and static dissipation.
Thermal Stability: Operates effectively from -50°C to 200°C.
Chemical Resistance: Resists acids, alkalis, and solvents (compatible with epoxy, polyester resins).
Surface Versatility: Smooth or textured finishes for aesthetic or functional requirements.
| Step | Description |
|---|---|
| Fiber Production | PAN-based precursor fibers are stabilized and carbonized at 1,000–3,000°C. |
| Short Fiber Cutting | Carbon fibers are cut into 3–15 mm lengths for uniform distribution. |
| Wetting & Blending | Fibers are dispersed in a resin bath (epoxy/phenolic) with sizing agents. |
| Mat Formation | Wet fibers are layered and pressed into non-woven mats via vacuum forming. |
| Curing | Heat/pressure curing ensures resin cross-linking and fiber-resin bonding. |
| Quality Control | Metrics: Fiber content (30–50%), surface resistivity, tensile strength. |
Storage: Keep dry in cool, ventilated areas (15–25°C) to prevent moisture absorption.
Handling: Wear PPE (gloves, goggles) to avoid fiber irritation; use sharp tools for cutting.
Chemical Exposure: Avoid contact with strong oxidizers or aromatic hydrocarbons.
Temperature Limits: Do not exceed 200°C unless specified for high-temperature grades.
Adhesion Optimization: Surface primers may be required for optimal resin bonding.
