Tribological Behaviour of Polymer Matrix Composites Reinforced with Metal (WC) and Metal Oxide (TiO2)

Abstract

In this work tribological behaviour and hardness of pigment (TiO₂) and Tungsten carbide (WC) reinforced epoxy resin composites had been examined. TiO2 and WC particles were included inside the epoxy matrix in three distinctive volume portion (0%, 5% and 10%). Examples were made by hand layup strategy by throwing epoxy glue and reinforcement blend in molds. Wear and hardness (shore-D) test were acted in accordance with the ASTM G99-95a and ASTM D 2240 guidelines. Tribological properties of specimen were checked by pin on disk founded by varying load on disk and its speed. From results it was observed that both TiO₂ and WC particle reinforcement shows reduction in wear and hardness of epoxy will increase by addition of WC particles compared to TiO₂
