PC Carbon Fiber Woven Fabric Prepreg Tape for Automotive Lightweight Parts Impact Resistance
Product Spotlights
Introducing our PC Carbon Fiber Woven Fabric Prepreg Tape – a high-performance solution engineered for the demanding requirements of automotive lightweight parts and impact resistance. As a manufacturer with over two decades of expertise (since 1998), we combine advanced composite technology with rigorous quality control to deliver a prepreg tape that offers an exceptional balance of strength, weight savings, and toughness. Our products are trusted by global markets spanning North America, Europe, Asia, and beyond, with annual export values exceeding US$5 million. This prepreg tape is designed to help automotive engineers achieve weight reduction without compromising structural integrity, making it an ideal choice for crash-relevant components, chassis reinforcements, and body panels.
Key Features & Technical Specifications
- Resin System: Polycarbonate (PC) matrix – provides excellent impact resistance, ductility, and thermal stability compared to standard epoxy systems. The PC resin absorbs energy efficiently under impact, reducing the risk of brittle fracture.
- Carbon Fiber Reinforcement: High-grade 3K/6K/12K woven fabric with uniform tow distribution, offering superior tensile strength (≥3500 MPa) and modulus. The woven structure enhances damage tolerance and load transfer.
- Prepreg Format: Pre-impregnated with precisely controlled resin content (35–45% by weight), ensuring consistent fiber-to-resin ratio and void-free laminates. The tape is tacky at room temperature and cures at moderate temperatures (120–160°C) for efficient processing.
- Dimensions & Customization: Available in standard widths of 50mm, 100mm, and 150mm, with thickness options from 0.15mm to 0.25mm. Custom widths, lengths, and roll sizes are available upon request to fit specific production needs.
- Weave Styles: Plain weave for balanced bidirectional properties, or twill weave for improved drapeability on complex curves. Both styles are optimized for high fiber volume fraction (55–60%).

Benefits for Automotive Applications
- Weight Reduction: Up to 50% lighter than steel and 30% lighter than aluminum, enabling significant fuel efficiency and lower emissions.
- Impact Energy Absorption: The PC matrix combined with carbon fiber creates a tough, ductile composite that absorbs energy during crash events, enhancing passenger safety.
- Fatigue Resistance: Excellent cyclic load performance, ideal for suspension components, structural reinforcements, and battery housings.
- Design Flexibility: The prepreg tape can be cut, laid up, and cured using standard autoclave, vacuum bag, or compression molding processes. It conforms to complex geometries without wrinkling.
- Surface Finish: Smooth, void-free surface after curing reduces painting and finishing steps.

Frequently Asked Questions (FAQ)
- What is the shelf life of this prepreg tape? When stored at -18°C (freezer), the shelf life is 12 months from date of manufacture. At room temperature (25°C), it is 30 days. We recommend refrigerated storage for optimal tack and curing properties.
- Can this tape be used for vacuum bagging only, or does it require autoclave? It can be cured under vacuum bag pressure (0.1 MPa) in an oven, or in an autoclave with higher pressure (0.3–0.7 MPa) for enhanced fiber volume and lower void content. Both methods are suitable; we provide recommended cure cycles.
- Is the PC resin compatible with common matrix resins like epoxy? PC is a thermoplastic resin, which differs from thermoset epoxies. It offers higher impact resistance but requires processing at higher temperatures. It is not typically co-cured with epoxy. However, it can be welded or bonded using adhesives.
- What are the typical applications in automotive? Common uses include door impact beams, bumper brackets, seat frames, roof structures, underbody shields, and electric vehicle battery enclosures. The tape is particularly suited for parts that require high strength and energy absorption.
- Can you provide cut-to-size strips or reels? Yes, we can slit the prepreg tape into custom widths (down to 10mm) and lengths, and supply it in roll form with protective release film. Please specify your requirements.
- What is the coefficient of thermal expansion (CTE) of the cured laminate? The CTE is approximately 2–5 × 10⁻⁶ /°C in the fiber direction, significantly lower than metals, which helps reduce thermal distortion in automotive assemblies.
- Do you offer color options other than black? The standard carbon fiber prepreg is black. However, we can add pigments or surface coatings upon request for aesthetic or identification purposes. Custom colors may affect mechanical properties slightly.
- How do you ensure product consistency from batch to batch? We follow strict internal quality control procedures, including resin content testing, fiber inspection, tack measurement, and differential scanning calorimetry (DSC) for cure behavior. Each batch is traceable and comes with a certificate of analysis.
