Influence of Filler Size on the Tribological Performance of Epoxy Composites

In this investigation, the influence of filler size (micro and nano scale) and applied load values on the tribological behaviour of epoxy composites were studied. Wear tests were carried out on pin-on-disc arrangement. The tribo elements consist of the polymer pin and DIN 1.2344 steel counterface disc. Test conditions were 5-15N applied load values, sliding speed of 0.8m/sec, 2000m sliding distance and at dry atmospheric conditions. The friction coefficient and specific wear rate values for the epoxy composite material were obtained and evaluated. The results show, the large influence of filler size and type on the performance of the epoxy composite.
