Product Introduction & Features
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.
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.
Manufacturing Process
| 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. |
Usage Precautions
- 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.
