Experimental investigations had been done in this research to demonstrate the effect
of glass fiber and Ceramic fillers contents on the tribological behaviour of (15%volume
fraction) glass-epoxy composite system under varying volume fraction, load, time and
sliding distance. The wear resistance were investigated according to ASTM G99-05
(reapproved 2010) standard using pin on disc machine to present the composite tribological
behaviour. The influence of three ceramic fillers granite, perlite and calcium carbonate
(CaCO3) on the wear of the glass fiber reinforced epoxy composites investigated under dry
sliding conditions. The effect of variants in volume fraction, applied load, time and sliding
distance on the wear behaviour of polymer composites is studied by applied pin –on-disc
method . In the experiments with wear test pin having flat face in contact with hardening
rotating steel disc, sliding speed, time and loads in the range of 200 RPM, 300–900s and
40–60 N respectively was used. It is observed that the wear resistance increase with the
increasing of reinforcement material volume fraction while, the wear rate increases with
increasing of applied load, time and sliding distance. The results showed that the filler of
granite, perlite and CaCO3 as filler materials in glass epoxy composites will increase the
wear resistance of the composite by 76.15%, 73.8%, 71.8%respectively and greatly than
glass fiber fillers epoxy composite only and granite filled GE Composite exhibited the
maximumwear resistance
