The wear behaviour of poly (ether-ether-ketone) (PEEK) composite was investigated according to the load and test speed. Three types of materials were studied: first, neat PEEK, PEEK with 30 wt. % carbon fiber (PEEK CF30), and third, PEEK with carbon nanotubes (PEEK ELS NANO). Tribological tests were performed on the universal tribometer UMT-2, using a pin-on-disc device. The friction coefficient and wear rate for the composites studied were analysed. Tests carried out have allowed the examination of the influence of load and speed on the friction coefficient and wear rate under dry sliding regime. Also, structural changes were noticed by optical and SE microscopy, and wear types of surface were discussed. As a result of experimental tests, it was established that PEEK composite with carbon fiber/carbon nanotubes exhibit good wear behaviour under operating conditions.
