Friction and Wear Performance of Glass Fiber Reinforced Poly-Ether-Ether-Ketone Composite against Different Polymer Counterparts

In this study, the friction and wear performance of 30wt.% glass fiber reinforced poly-ether-ketone (PEEK+30%GF) composite materials against poly-ether-imide (PEI) polymer blend and poly-phenylene-sulphide (PPS) polymer composite materials under dry sliding condition were evaluated. Friction and wear tests were carried out on a pin-disc arrangement at the sliding speed of 0.5m/s and under 0.707, 1.41, and 2.12(N) applied loads condition. 10wt.% poly-tetra-fluoro-ethylene (PTFE) filled poly-ether-imide polymer blend (PEI+10%PTFE) and 40wt.% glass fiber reinforced poly-phenylene-sulphide (PPS+40%GF) composite counter-face disc materials were used. The results show that the coefficient of friction and specific wear rates for PEEK+30%GF polymer composites against steel, polymer blend and polymer composite material increases slightly with the increment of applied pressure values. Finally, the specific wear rates for PEEK polymer composite against PTFE filled PEI polymer blends and glass fiber reinforced PPS composite under dry sliding conditions are in the order of 10 -14 m 2 /N and 10 -14 m 2 /N, respectively. The results suggested that it is more convenient to use PEEK+30%GF composite against steel for tribological applications.
