Polymer Matrix
Composites

Polymer Matrix Composites are advanced materials consisting of a polymer matrix reinforced with fibers (such as carbon, glass, or aramid) or particles, designed to deliver high structural performance. They combine low weight, high mechanical strength, and excellent corrosion resistance, making them particularly suitable for aerospace, automotive, and energy applications. Thanks to the ability to tailor material properties to specific design requirements, polymer composites enable highly efficient and innovative engineering solutions.

C-Preg® 400 

At Petroceramics, we’ve taken this concept further with C-Preg® 400 — a proprietary, flame- and heat-resistant prepreg developed from our patented technology.

C-Preg® 400 is safe, non-toxic, and easy to process, whether in molding presses or autoclaves, at temperatures ranging from 180 °C to 350 °C. Certified V0 under the UL94 Flammability Standard, it’s designed for long-term, high-temperature applications — withstanding up to 400 °C for short periods and 350 °C continuously.

Positioned between traditional prepregs and ceramic matrix composites, C-Preg® 400 is the ideal solution for:

• Thermal barriers (also in sandwich structures with aluminum honeycomb)
• Exhaust systems
• Engine components
• High-performance braking system parts

Already trusted by top teams in Formula 1 and MotoGP, C-Preg® 400 delivers the performance, safety, and reliability demanded by the world’s most extreme environments.
