Research on tribological behavior of PEEK and glass fiber reinforced PEEK composite
The tribological behaviors of pure polyetheretherketone (PEEK) and PEEK composites reinforced by 30wt％ short glass fibers (GF) were comparatively evaluated on a ball-on-disc configuration at room temperature. The effects of applied load and sliding time on the friction coefficient and wear loss of the GF/PEEK were examined. The mechanical property, morphology and thermal performance of the composite were studied. The results indicated that the friction coefficient and wear loss of the composite increased gradually and tended to be a stable state as the increase of applied load and sliding time. The GF/PEEK has an excellent wear resistance, compared with PEEK. The SEM and EDS indicated that the short glass-fibers were extruded from the composite rather than pulverized into the composite. Compared with that of pure PEEK, the thermal decomposition temperature of GF/PEEK composite had an increase of 75℃. The tensile strength and flexural strength of the composite were increased by 64％ and 66％, respectively.
