In this work the effect of different types of fibres on the tribological properties of reinforced PEEK (polyether-ether-ketone) composites was studied. The composites were manufactured by using a compression-moulding technique. Tribological experiments were conducted to measure the wear resistance and the friction coefficient. Additionally, the influence of different fibres in wear resistance under low and high pressures was examined. Pin-on-disk experiments and scanning electron microscope (SEM) inspections were employed in the study.
