Abstract: Fibre reinforced composite materials have been used in main parts of structures; an accurate evaluation of their erosion behaviour becomes very important. According to previous researchers, erosion wear holds about 8% of there regular wear in industrial production. In this study, short glass fibre (SGF) reinforced epoxy-based isotropic polymer composites are fabricated with five different fibre weight-fractions. This paper describes the processing and characterisation of a class of hybrid composites prepared by filling of SiC particulates in short glass fibre reinforced epoxy resin and compared with the published research report on bidirectional glass fibre (BGF) reinforced epoxy composites. For this purpose, a novel technique like Taguchi experimental design is employed. It is observed that the erodent temperature, filler content, impact velocity, impingement angle are the most significant factors effecting the erosion rate. The peak erosion rate is found to be occurring at an impingement angle of 75° for both the set of composites and for unfilled composites the impingement angle lies in the range of 60°. The morphology of eroded surfaces is examined by using scanning electron microscopy (SEM) and possible erosion mechanisms are discussed.
