Abstract
Various polyaryletherketone-based composites were investigated with regard to their high temperature dry-sliding behaviour. In the range between room temperature and 220 deg C, all grades with a polytetrafluoroethylene (PTFE) content of 10-15 wt.% exhibited a friction behaviour that is very similar to that of neat PTFE. Studies of the wear--pv relationship of some of the grades showed that fibre contents of 30 wt.% are found to stabilize the specific wear, up to pv products of 16 MPa m s exp --1 .
