Carbon Fiber Prepreg | Precision Engineered Composite Solutions
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.
Fiber Preparation:
Carbon fibers (e.g., T700, T800) are produced via pyrolysis of polyacrylonitrile (PAN) precursors, achieving high tensile strength and stiffness.
Resin Impregnation:
Fibers pass through a resin bath or film-coating system to achieve uniform resin saturation (30–40% resin content).
B-Staging:
Partial curing at 80–120°C creates a tacky, tack-free state for easy handling and storage.
Layer Consolidation:
Multiple prepreg layers are stacked and aligned using automated cutting and placement systems.
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.
