Lightweight Epoxy Carbon Fiber Cloth Sheets Carbon Fiber Woven Fabric With Thermal Stability

Carbon Fiber Prepreg is a high-performance composite material combining carbon fibers with a thermosetting resin matrix (typically epoxy). Prepreg undergoes a controlled partial curing process (B-staging), resulting in a tacky, ready-to-use material that eliminates manual resin application. This ensures consistent fiber-resin ratios, superior mechanical properties, and reduced waste.

• Exceptional Strength-to-Weight Ratio: Delivers 5-7× higher strength than steel at 1/4 the weight.
• Uniform Resin Distribution: Automated processes guarantee precise fiber alignment and resin saturation.
• Thermal Stability: Operates effectively up to 300 °C without significant degradation.
• Corrosion Resistance: Impervious to acids, alkalis, and moisture, ideal for harsh environments.
• Customizability: Adjustable fiber orientation (0°, ±45°, 90°) and resin systems (epoxy, phenolic) to meet specific performance needs.

1. Fiber Preparation:

   Carbon fibers (e.g., T700, T800) are produced via pyrolysis of polyacrylonitrile (PAN) precursors, achieving high tensile strength and stiffness.

2. Resin Impregnation:

   Fibers pass through a resin bath or film-coating system to achieve uniform resin saturation (30-40% resin content).

3. B-Staging:

   Partial curing at 80 -120°C creates a tacky, tack-free state for easy handling and storage.

4. Layer Consolidation:

   Multiple prepreg layers are stacked and aligned using automated cutting and placement systems.

5. Curing:

   Heat and pressure (120-180°C, 0.5-2.0 MPa) in autoclaves ensure full resin curing and void elimination.

• Storage:

  Store at -18 °C to halt curing; thaw for 24 hours at room temperature before use.

• Handling:

  Wear PPE (gloves, respirators) to avoid fiber irritation and inhalation hazards.

• Curing Parameters:

  Maintain strict temperature and pressure controls to prevent warping or void formation.

• Surface Preparation:

  Clean molds with release agents (e.g., PVA wax) to ensure part release.
