Carbon Fiber UD Prepreg

>> Carbon Fiber UD fabrics are usually obtained by carbonizing and graphitizing organic fibers6. During the manufacturing process, carbon fibers are woven or laid up in different ways to form fabrics with various structures and properties.

FAQ

What curing conditions are recommended for CUD150/33%-1000 with epoxy resin?

For mold forming (e.g., automotive parts): 120–150°C for 30–90 minutes (adjust based on thickness). For pipes (e.g., fishing rods): 80°C for 30 minutes + 125°C for 90 minutes.

Can the resin content of CUD150/33%-1000 be customized?

Yes. We offer resin contents from 20% (high-strength aerospace parts) to 50% (flexible sports equipment)—contact us for custom ratios.

How should CUD150/33%-1000 be stored to prevent resin degradation?

Store at -18°C (freezer) to extend shelf life to 6 months; thaw at room temperature for 24 hours before use—do not refreeze after thawing.

Suitable Production Process

Carbon Fiber UD Laying: 12K fibers are laid in a 0° direction, with tension control to avoid fiber breakage.

Resin Coating: Epoxy resin (33% content) is uniformly coated onto fibers using a precision roller, with temperature control (40–50°C) to ensure proper viscosity.

Lamination & Cooling: Coated fibers are laminated with release paper to prevent sticking, then cooled to 20–25°C to set the prepreg.

Curing Preparation: Each roll is labeled with curing parameters (e.g., 120°C for 90 minutes for mold forming) to guide end-user processing.

Characteristics

Consistent Fiber-Resin Ratio: 33% resin content ensures no voids, delivering maximum strength (3400MPa tensile strength) and modulus (230GPa).

Easy Molding: Pre-impregnated resin requires only heat and pressure to cure, simplifying manufacturing of complex parts (e.g., golf club heads).

High Temperature Resistance: With bismaleimide resin, it withstands up to 250°C—suitable for aerospace engine parts exposed to high heat.

Low Void Content: <1% voids improve fatigue resistance, making it ideal for aircraft components that undergo 10,000+ flight cycles.
