EFFECT OF E-GLASS FIBER LOADING ON WEAR BEHAVIOUR OF POLYESTER COMPOSITES UNDER DRY CONDITION
Keywords:
Polymer-matrix composite, wear, Glass Fiber, FESEMAbstract
Wear behaviour of E-glass reinforced polyester composites with different weight percentages of resin and fiber have been studied using pin-on-disk method. The wear tests were conducted for the different normal loading of 5N, 10N and 15N with the varying sliding distances of 500m, 1000m and 1500m. The test results indicate that the 70 wt % of resin and 30 wt % of fiber increases the wear resistance of the composites. The factors affecting the wear behaviour of composites such as weight percentage of resin, fiber and the bonding strength between them were thoroughly investigated. Wear mechanism of the composites were studied by analysing the worn surface morphology of the specimens using field emission scanning electron microscopy (FESEM) at high resolution.
