0.2mm Thickness PC/Carbon Unidirectional Prepreg Tape With 300GPa Modulus for High-Stiffness ApplicationsNegotiableMOQ: 1 Square Meter
As a dedicated manufacturer with over 25 years of experience in advanced composite materials (established in 1998), we proudly present our PC/Carbon Woven Prepreg Tape specifically engineered for aerospace structural components. This 0.2mm thick, 50mm wide tape cures at 150°C, offering an optimal balance of high strength, lightweight performance, and dimensional stability for demanding applications. Our product is the result of rigorous quality control and continuous R&D, ensuring consistent resin content and fiber alignment that meet the stringent requirements of the aerospace industry.
Our prepreg tape combines a polycarbonate (PC) toughened epoxy resin system with a carbon woven fabric, delivering exceptional impact resistance and fatigue life. The 0.2mm thickness allows for precise layup in complex geometries, while the 150°C curing temperature reduces energy consumption and cycle time compared to high-temperature systems. With an annual export value of US$5-10 million and a global presence across North America, South America, Europe, and Asia, we have established a reliable supply chain for aerospace manufacturers.
Key Product Features & Technical Specifications
- High-Performance Resin System – PC-modified epoxy provides excellent toughness and adhesion to carbon fibers, reducing micro-cracking under thermal cycling.
- Consistent Fiber Volume – Precision coating ensures uniform resin content (38-42% by weight), guaranteeing predictable mechanical properties.
- Low Outgassing – Suitable for vacuum bag and autoclave processes, meeting aerospace outgassing requirements.
- Customizable Width – Standard width is 50mm; other widths (25mm, 100mm) are available upon request.
- Long Tack Life – Tack retention at room temperature exceeds 10 days, allowing flexible layup schedules.
- Excellent Storage Stability – 6-month shelf life at -18°C, with 30-day out-time at 25°C.

Advantages & Customer Benefits
For aerospace structural components such as ribs, spars, stiffeners, and brackets, this prepreg tape offers a significant weight reduction over metallic alternatives while maintaining high stiffness and strength. The 150°C curing temperature enables faster processing in mid-temperature autoclaves or ovens, reducing energy costs and production lead times. The PC-modified resin system provides superior damage tolerance, making it ideal for primary and secondary structures subject to impact loads.
Manufacturing benefits include excellent drapeability for complex contours, minimal resin bleed, and easy handling due to the material's tacky but non-sticky surface. The 50mm width is optimized for automated tape laying (ATL) and hand layup processes, reducing waste and improving ply alignment. Our factory can also supply the tape in continuous lengths up to 100 meters per roll, minimizing splice joints.
Trust & Reliability
Since 1998, our factory has been a trusted supplier to the global aerospace and advanced composites industry. With an annual export value of US$5-10 million, we ship from major Chinese ports including Tianjin, Qingdao, Shanghai, and Foshan, ensuring timely delivery to markets across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and Europe. Our quality management system covers every step from raw material inspection to final packaging, and we offer full traceability documentation for each batch. We invite you to contact us for technical data sheets, samples, or custom formulations. Let our expertise support your next aerospace project.
Frequently Asked Questions (FAQ)
-
Q: What is the shelf life of this prepreg tape?
A: The recommended shelf life is 6 months when stored at -18°C (freezer). It can be kept at room temperature (25°C) for up to 30 days without significant loss of tack or reactivity. -
Q: Can I use this tape for component repair?
A: Yes, the 0.2mm thickness and 50mm width are suitable for patch repairs on aerospace structures, provided the repair area is within the tape's mechanical capabilities. Contact our technical team for specific repair procedures. -
Q: Is the resin system compatible with standard autoclave vacuum bagging?
A: Absolutely. The PC-modified resin has low outgassing and is designed for vacuum bag curing up to 0.8 bar pressure. It can also be cured in an oven with vacuum only. -
Q: What are the minimum order quantities (MOQ)?
A: MOQ for standard 50mm width is 10 linear meters. For custom widths or special resin formulations, please inquire for MOQ details. -
Q: Do you provide material certificates (e.g., Mill Test Report)?
A: Yes, each batch is supplied with a Certificate of Conformance (CoC) including resin content, fiber areal weight, and mechanical test results. Additional inspection reports can be provided upon request. -
Q: How does this tape compare to standard 120°C curing prepregs?
A: The 150°C curing system offers higher Tg (≥180°C) and better high-temperature performance, making it more suitable for aerospace hot/wet environments. The PC toughener also improves impact resistance compared to standard epoxy. -
Q: Can I get a sample before ordering?
A: Yes, we offer free samples of up to 0.5 linear meter for evaluation. Shipping costs are at your expense. -
Q: Are there any special storage requirements for the tape?
A: Store in a sealed bag at -18°C, away from moisture and direct sunlight. Before use, allow the tape to warm to room temperature in the sealed bag to prevent condensation.
