Abstract
In this study, a new class of low cost hybrid composites consisting of glass-epoxy and filled with four different weight proportions (0 wt%, 10 wt%, 15 wt% and 20 wt%) of granite particulates (a solid waste generated from stone processing industries) are developed. Mechanical study reveals that hardness, tensile modulus and impact energy of these composites are improving with filler addition while a steady decline in tensile and flexural strength is observed. The erosion rates of these composites are evaluated at different impingement angles (30–90°), impact velocities (33–68 m/s) and erodent sizes (100–250 µm) following the erosion test experiments in an air jet type test rig. An optimal parameter setting is determined for minimum erosion rate and subsequently validated by conducting confirmation experiment as per Taguchi methodology. Erosion test results indicate that the incorporation of granite particulates results in improvement of erosion wear resistance of glass-epoxy composites. Different modes of material removal, wear craters and other qualitative attributes are examined by a scanning electron microscopy during erosion experiment of the samples.
