Carbon Fiber Prepreg | Precision Engineered Composite Solutions​​

​​1. Product Introduction​​

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. Key advantages include:

• ​​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.

​​2. Manufacturing Process​​

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.

​​3. Usage Precautions​​

• ​​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.
