Influence of SiO2 Fillers on Sliding Wear Resistance and Mechanical Properties of Compression Moulded Glass Epoxy Composites

The E-glass woven fabric-epoxy (LY 556) (GE) composites have been fabricated with varying amounts of silicon oxide (SiO2) particulate filler viz., 3, 6 and 9 wt % by compression molding followed by hot curing. The fabricated composites were characterized by mechanical properties such as tensile behaviour, flexural behaviour and interlaminar shear strength (ILSS). The effect of silica content on the sliding wear properties such as wear loss, specific wear rate and coefficient of friction of GE composites have been investigated at velocity of 5m/s and constant abrading distance of 1200 m with different loads viz., 30N, 60N and 90N by using pin-on-disc machine. Wear out surface of all the composites were studied using scanning electron microscopy (SEM)
