Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998, proudly presents our PC/Carbon Woven Prepreg Tape – a high-performance composite material engineered for the automotive industry’s lightweight parts. With an annual export value exceeding $5 million and serving markets across North America, South America, Europe, Asia, and beyond, we bring decades of expertise in precision fabric and composite solutions. This 3K twill prepreg tape, featuring a 0.25mm thickness and 300mm width, combines the strength of carbon fiber with the impact resistance of polycarbonate (PC) in a woven hybrid form, offering an optimal balance of weight reduction and mechanical performance.
Our prepreg tape is pre-impregnated with a carefully formulated epoxy resin system, ensuring consistent resin distribution and excellent tack for easy layup and curing. Designed specifically for automotive lightweight components, it delivers exceptional stiffness-to-weight ratio, impact resistance, and dimensional stability. Whether you are manufacturing body panels, chassis reinforcements, or interior structural parts, this tape streamlines your production process while maintaining the highest quality standards.
Key Features & Technical Specifications
- Hybrid Fiber Architecture: PC (polycarbonate) fibers are woven together with 3K carbon fibers in a twill pattern, providing enhanced toughness and energy absorption compared to pure carbon prepregs.
- Precise Thickness Control: 0.25mm ±0.02mm ensures uniform thickness across the entire roll, critical for consistent part quality and reduced waste.
- Optimal Width for Automation: 300mm width is ideal for automated layup machines, tape placement, and hand layup processes, reducing material trimming and splicing.
- Low Void Content: Advanced impregnation process produces prepreg with void content below 1%, ensuring high mechanical properties after curing.
- Excellent Shelf Life: 6 months at -18°C storage, with 30 days out-life at room temperature (20°C) for convenient handling.
- Customizable Resin Systems: Available in different epoxy formulations (e.g., fast-cure, medium-cure, high-temp) upon request to match your specific curing cycle and performance requirements.

Advantages for Automotive Lightweight Parts
- Weight Reduction: Up to 40% lighter than steel and 30% lighter than aluminum, directly contributing to fuel efficiency and EV range extension.
- High Impact Resistance: The PC fiber component absorbs energy during impact, making it ideal for safety-critical parts like bumper beams and door panels.
- Design Flexibility: Twill weave offers excellent drapeability for complex geometries, reducing the need for multiple plies and simplifying mold design.
- Cost-Effective Production: Ready-to-use prepreg eliminates wet layup, reduces curing time, and minimizes labor compared to traditional composite manufacturing.
- Consistent Quality: Factory-controlled impregnation ensures zero resin-rich or dry spots, guaranteeing repeatable part performance.
Our prepreg tape is supplied in vacuum-sealed rolls with desiccant to maintain optimal resin reactivity. Each roll is individually labeled with batch number, manufacturing date, and storage conditions for full traceability. We offer custom slitting (e.g., 100mm, 150mm widths) and custom lengths to meet your production requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between PC/Carbon hybrid prepreg and pure carbon prepreg?
A: The PC (polycarbonate) fibers are woven together with carbon fibers to improve impact toughness and energy absorption. While pure carbon prepreg offers higher stiffness, the hybrid version provides better ductility and damage tolerance, making it particularly suitable for automotive parts that need to withstand crash loads. -
Q: Can I use this prepreg for high-temperature applications?
A: Yes, we offer a high-temperature epoxy resin option with a glass transition temperature (Tg) of up to 180°C. Please specify your required cure cycle and operating temperature when ordering, and we can customize accordingly. -
Q: How long can I keep the prepreg at room temperature before use?
A: The out-life at room temperature (20°C) is 30 days when stored in a sealed bag. After that, the resin may partially cure, affecting tack and flow. We recommend storing at -18°C for maximum shelf life of 6 months. -
Q: What curing method is recommended?
A: Standard cure is performed in an autoclave or vacuum bag oven at 120°C to 150°C for 60-90 minutes. For fast-curing versions, we can provide a resin that cures in 30 minutes at 140°C. We also support press curing for flat parts. -
Q: Can you cut the tape to narrower widths?
A: Absolutely. We offer custom slitting services for widths from 50mm to 300mm with a tolerance of ±1mm. Please inform us of your required width when placing an order. -
Q: Is the prepreg compatible with automated tape laying (ATL) machines?
A: Yes, the 300mm width and consistent tack make it suitable for automated tape laying and fiber placement. The resin is formulated to provide stable tack for at least 2 hours at room temperature, ensuring smooth robotic handling. -
Q: What is the minimum order quantity (MOQ) for this product?
A: The MOQ is 10 square meters for standard stock items. For custom resin or width, MOQ may be 50 square meters. Please contact our sales team for exact quantities based on your project size. -
Q: What certifications do you hold for quality control?
A: As a manufacturer focused on wire mesh and composite materials, we follow internal quality procedures based on ISO 9001 principles. We do not claim specific third-party certifications unless explicitly requested. However, we can provide material test reports (MTR) for each batch upon request.
