As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory takes pride in offering high-performance Carbon Fiber Prepreg Rolls engineered for demanding industrial applications. Our 1.0m width, 145g/m² areal weight prepreg is designed for 120°C curing, providing an optimal balance of strength, weight savings, and process efficiency. With over two decades of experience in composite material production, we deliver consistent quality roll after roll, making us a reliable partner for aerospace, automotive, and sports equipment manufacturers worldwide.
Our prepreg rolls feature a carefully controlled resin content and uniform fiber distribution, ensuring predictable mechanical properties and easy handling during layup. The 50-meter roll length minimizes waste and allows for continuous production runs. Whether you need structural components, lightweight panels, or high-performance sporting goods, this carbon fiber prepreg offers the reliability and performance your projects demand.
Key Product Features & Benefits
- Uniform Resin Impregnation: Advanced coating technology ensures consistent resin distribution across the entire width, eliminating dry spots and reducing void content in cured laminates.
- Optimized 120°C Cure Cycle: Designed for low-temperature curing, this prepreg reduces energy costs and allows compatibility with standard oven equipment. Cure time can be adjusted from 30 to 90 minutes depending on thickness.
- Excellent Tack & Drape: The prepreg offers ideal tack for complex shapes and good drapeability, making it suitable for hand layup, automated tape laying, and compression molding processes.
- Long Out-Life & Shelf Life: With proper storage at -18°C, the roll can be stored for up to 12 months. Out-life at room temperature (21°C) exceeds 30 days, providing flexibility for production scheduling.
- High Fiber Volume Fraction: Achieves approximately 60% fiber volume after curing, delivering superior specific strength and stiffness compared to standard prepregs.
- Low Volatile Content: Manufactured with low-VOC resin systems, meeting environmental regulations and improving workplace safety.

Application Advantages
This prepreg is ideal for manufacturing structural components where weight reduction and high strength are critical. In the aerospace sector, it is used for interior panels, drone frames, and secondary structures. Automotive applications include body panels, chassis components, and electric vehicle battery enclosures. For sports equipment, it produces bicycle frames, tennis rackets, and fishing rods with superior stiffness-to-weight ratio. The 120°C cure cycle allows compatibility with epoxy-compatible core materials such as Nomex, aluminum honeycomb, and foam cores, enabling sandwich panel construction.
Additionally, the prepreg's excellent surface finish reduces post-curing finishing work. The roll format facilitates automated cutting with CNC routers or laser cutters, minimizing material waste. Our manufacturing process ensures consistent thickness and resin content, crucial for achieving repeatable mechanical properties across batches.

Frequently Asked Questions (FAQ)
-
Q: What is the shelf life of this prepreg, and how should it be stored?
A: The shelf life is 12 months when stored at -18°C or below. For short-term use (up to 30 days), it can be kept at room temperature (21°C) in a sealed bag. Always store away from moisture and direct sunlight. -
Q: Can I use this prepreg with a vacuum bagging process?
A: Yes, it is suitable for vacuum bagging. Recommended vacuum pressure is 0.8–1.0 bar. The prepreg's resin system has low flow during cure, which helps maintain good consolidation. -
Q: Is the prepreg available in different widths or lengths?
A: Yes, we offer custom widths from 0.5m to 1.5m and custom lengths up to 200m per roll. Please contact our sales team for non-standard sizes. -
Q: What is the typical cure cycle for this prepreg?
A: The recommended cure cycle is: heat from room temperature to 120°C at 1–3°C/min, hold at 120°C for 60 minutes, then cool down at ≤ 3°C/min. For thicker laminates, a longer hold time may be required. -
Q: Does this prepreg contain any hazardous materials?
A: The resin system is formulated to meet RoHS and REACH requirements. It contains low volatile organic compounds (VOCs). However, proper personal protective equipment (gloves, safety glasses) should be worn during handling. -
Q: Can I use this prepreg with automated tape laying (ATL) machines?
A: Yes, the prepreg has consistent tack and width tolerance suitable for ATL processes. We recommend conducting a trial run to confirm compatibility with your specific equipment. -
Q: What is the typical fiber volume fraction after curing?
A: For a standard cure cycle, the fiber volume fraction is approximately 60% ± 3%. This can vary depending on the stacking sequence and applied pressure. -
Q: Do you provide samples before bulk order?
A: Yes, we offer sample rolls (e.g., 1m x 1m sheets) for testing. Please contact us to arrange a sample and discuss your requirements.
