PEEK-Based Composites

This brochure explains that semi-crystalline polyaryletherketone (PEEK) can be used as a matrix for thermoplastic composite prepregs made of carbon, glass or aramid continuous fibers. It highlights the polymer’s ability to withstand continuous operating temperatures of up to 260°C in low-stress applications and 120°C wet in aerospace structural applications. It discusses the stages of composite forming, including heating, pressurization and cooling, and it details the compatibility of PEEK-based composites with a range of rapid, automated and economical fabrication processes. A section on the techniques that can be used to bond and weld the composites, such as ultrasonic, vibration, hot plate and induction, is also included.
