Synergistic Effects of Micro Size Flyash Particulate and Glass Fiber on Friction and Wear of Vinylester Hybrid Composites under Dry and Water Lubricated Sliding Condition

In this paper the tribological performance of vinylester and its composites under dry and water lubricated sliding conditions has been investigated. For investigating the friction and wear tests were carried out on a pin on rotating disc under ambient conditions at normal applied loads of 10, 30 and 50N and under sliding speed of 1.6, 2.8 and 4.0 m/s. The results showed that the coefficient of friction decreases with the increase in applied normal load under both dry and water lubricated condition. The specific wear rate of GFR vinylester composite reduces significantly with the addition of fly ash particulates.
