Two polyphenylene sulphide matrix-based composites were investigated: PPS GF 40 (PPS -polyphenylene sulphide +40% glass fibers) and PPS PVX (PPS - polyphenylene sulphide +10% PTFE+10% carbon fibers +10% graphite). The tribological properties of these composites were tested on a Universal Tribometer UMT-2 (CETR) apparatus (pin-on-disc test, in dry sliding, with the help of a pin-on-disk tribotester. The tribological behaviour was found to depend on the adding material(s) in the tested composites and better results were obtained for the composite containing solid lubricants (PTFE and graphite).
