A new product family of carbon fiber reinforced polyaryletherketone (PAEK) composites for the aerospace industry is now offered by the U.K.’s Victrex (U.S. office in West Coshohocken, Penn.) in the form of unidirectional (UD) tape and laminate panels. The Victrex AE250 composites allow the production of continuously-reinforced components that reportedly perform exceptionally under load. Targeted are components used throughout an aircraft in primary and secondary structures including brackets, clips, clamps and housings.

The AE250 PAEK composites reportedly provide up to a 60% reduction in weight compared with metals such as aluminum, stainless steel and titanium. This development builds on the hybrid molding technology launched by Victrex in 2014. This process enables AE250 PAEK composites in the form of inserts analogue to metals to be overmolded with fiber-reinforced Victrex PEEK injection molding materials. It is not necessary to pre-heat the AE250 organosheets nearly up to the melting temperature before inserting them into the injection molding press. Benefits include improved cycle times, reduced energy consumption, elimination of secondary process steps, reduced scrap generation and also savings in installation expense.
