Fiber Glass Reinforcement;
In this study, the tribological performance of originally 40 wt.% fiber glass reinforced polyphenylene sulfide (PPS-G), polyamide 46 (PA46) and their blends were studied at dry sliding conditions. The materials were mixed and extruded on the twin screw extruder. The blends were dried and tribological test specimens were manufactured by using the injection machine. Wear tests were performed with the configuration of a polymer pin on a rotating X40CrMoV5-1 steel disc. Test conditions were atmospheric conditions having 60, 90, 120 N loads and 0.5, 1.0, 1.5 m/s sliding speeds. The obtained results proved that the coefficient of friction for PPS-G, PA46 and their blends is decrease while the applied load and sliding speed values are increase. On the other hand, the specific wear rate is in increase while the applied load and sliding speed values are in increase.
