As a manufacturer with over 20 years of experience in advanced materials, Anping County Boli Hardware Wiremesh Products Factory is proud to introduce our PPS UD carbon prepreg — a high-performance composite solution specifically engineered for the automotive industry's lightweighting needs. This unidirectional prepreg combines the exceptional thermal and chemical resistance of PPS (Polyphenylene Sulfide) resin with the superior strength-to-weight ratio of carbon fiber, making it an ideal choice for structural components that require crash resistance and fatigue performance. Our prepreg is designed to meet the demanding requirements of modern vehicle manufacturing, helping you reduce weight while maintaining safety and durability.
The product is manufactured using advanced impregnation technology, ensuring uniform resin distribution and consistent fiber alignment. This results in predictable mechanical properties and reliable processing behavior. Whether you are producing crash boxes, battery enclosures, or suspension components, our PPS UD carbon prepreg offers a balanced combination of lightweight design, impact energy absorption, and long-term cyclic loading capabilities.
Key Features & Benefits
- Outstanding Crash Resistance — High toughness and energy absorption capacity help protect occupants during collisions.
- Superior Fatigue Performance — Excellent resistance to repeated loading cycles, extending component lifespan.
- Lightweight — Up to 50% weight reduction compared to steel, contributing to fuel efficiency and electric vehicle range.
- High Temperature Resistance — PPS matrix can withstand continuous service temperatures up to 220°C, ideal for under-hood applications.
- Chemical Resistance — Resistant to automotive fluids such as oil, fuel, and coolant.
- Tailorable Mechanical Properties — Fiber orientation, resin content, and ply count can be customized to meet specific load requirements.
- Good Dimensional Stability — Low moisture absorption and thermal expansion coefficient ensure part precision.
- Ease of Processing — Compatible with compression molding, autoclave, and vacuum bagging techniques.

Our prepreg is supplied in roll form with a protective PE film, ensuring easy handling and layup. The material is slit to your specified width to minimize waste. We also offer trial samples for qualification purposes.
Applications in Automotive Lightweighting
- Crash structures — front rails, crash boxes, bumper beams
- Battery enclosures for electric vehicles
- Chassis components — control arms, suspension links
- Body panels — doors, hoods, trunk lids
- Interior reinforcement — seat frames, dash panels
- Under-hood parts — engine covers, heat shields
The combination of PPS and carbon fiber delivers excellent damping properties, reducing noise and vibration. Additionally, the material's inherent flame retardancy (UL94 V-0) makes it suitable for safety-critical components.

Frequently Asked Questions (FAQ)
-
Q: What is the storage life of this prepreg?
A: When stored in a sealed bag at -18°C (freezer), the shelf life is typically 12 months from the date of manufacture. At room temperature (20°C), the out-life is about 30 days. -
Q: Can the prepreg be used in high-temperature environments?
A: Yes. PPS resin has a continuous service temperature of 220°C, making it suitable for engine compartments and other hot zones. -
Q: Is the material compatible with compression molding?
A: Absolutely. Our prepreg is designed for compression molding, autoclave, and vacuum bagging. For compression molding, we recommend a dwell time of 5-10 minutes at 320-340°C under 10-20 bar pressure. -
Q: Can you provide customized fiber areal weight or resin content?
A: Yes. We offer customization of fiber areal weight from 100 to 300 g/m² and resin content from 30% to 45%. Please contact us with your requirements. -
Q: How does this prepreg compare to epoxy-based prepregs?
A: PPS offers superior temperature resistance, chemical resistance, and toughness compared to standard epoxy. It also has better fatigue performance and lower moisture absorption. However, processing temperature is higher. -
Q: Is the prepreg available in widths other than listed?
A: Yes, we can slit to your specified width, typically from 100 mm to 1000 mm, with a minimum order quantity. Please inquire. -
Q: Do you provide sample rolls for testing?
A: Yes, we offer A4-size sample sheets or small rolls for qualification. Contact our sales team for details. -
Q: What is the typical lead time for bulk orders?
A: For standard specifications, lead time is 2-3 weeks after order confirmation. Custom orders may require 4-6 weeks.
