Various polyaryletherketone-based composites were investigated with re
gard to their high temperature dry-sliding behaviour. In the range bet
ween room temperature and 220-degrees-C, all grade with a polytetraflu
oroethylene (PTFE) content of 10-15 wt.% exhibited a friction behaviou
r that is very similar to that of neat PTFE. Studies of the wear-pv re
lationship 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-1.
