In this paper the friction wear characteristics of vinylester and vinylester composites have been investigated under dry and water lubricated sliding conditions, under different applied normal load and sliding speed. The experiments have been carried on a pin on disc arrangement at normal temperature conditions. The results showed that with increase in the applied normal load and sliding speed the coefficient of friction and specific wear rate decreases under both dry and water lubricated sliding conditions. It is also found that a thin film formed on the counterface seems to be effective in improving the tribological characteristics. The worm surface examined by SEM showed that more of the fiber exposure and fiber breakage for vinylester composite resulting higher wear rate.
