JHFRTP PEI fiber-reinforced polyetherimide composite material

Product Overview

JHFRTPPEI series is a class of high-end, high-performance thermoplastic composite materials. It uses T300-grade -3K satin carbon fiber fabric, electronic-grade glass fiber fabric, needle-punched carbon fiber felt and other fiber forms as reinforcing materials, and amorphous thermoplastic polymer PEI as prepreg resin, which is formed by high-temperature hot pressing.

It possesses excellent properties such as light weight, high strength, high toughness, high damage resistance, fatigue resistance, resistance to damp heat, and corrosion resistance, and can be used at temperatures up to 250°C for extended periods. It is widely used in aerospace, medical devices, petrochemicals, automotive, and electronics/semiconductor industries.
