Friction and Wear PerforAmance of Short Carbon Fiber Reinforced Poly- ether-ether-ketone Thermoplastic Composite Against Polymer and Steel Material Counterparts
AbstractIn this experimental study, the tribological performance of 30wt.% short carbon fiber reinforced poly-ether-ketone (PEEK+30%CF) high performance thermoplastic composite against a stainless steel (SS) and a high performance thermoplastic polymer material such as 40wt.% glass fiber reinforced poly-phenylene-sulphite (PPS+40%GF) composite materials under dry sliding condition were evaluated. Tribological tests were carried out on a pin-disc wear test rig and under the sliding speed of 0.5 m/s and the applied pressures of 0.707, 1.41 and 2.12MPa conditions. The results show that the friction coefficient for carbon fiber reinforced PEEK composite against PPS+40%GF polymer composite and stainless steel materials increases slightly with the increment of applied pressure values. Furthermore, the specific wear rate for carbon fiber reinforced PEEK composite against PPS+40%GF composite increases but it decreases against stainless steel with the increment of applied pressure values. Finally, the wear rates for carbon fiber reinforced PEEK polymer composite against PPS+40%GF composite and stainless steel materials under dry sliding conditions are in the order of 10-14 and 10-15 m2/N, respectively. The results suggested that PEEK+30%CF-stainless steel pair is the best material pair for use in friction and wear applications in the study.
