Sliding Wear Behavior of Graphite Filled Glass-Epoxy Composites at Elevated Temperatures

Effect of filler material on sliding wear behavior of Glass-Epoxy (G-E) composites has been investigated. The sliding distance, applied load, sliding velocity and temperature are the parameters used for the study. The fabricated wear specimens were tested by using pin-on-disk test rig. The result shows that the wear loss increases with increase in temperature and applied load and under the same conditions the coefficient of friction decreases. However, graphite-filled G-E composite exhibits lower wear rate and lower coefficient of friction as compared to unfilled composite. The features of worn surfaces of the specimens were examined under scanning electron microscope.
