Wear Rate Behavior of Unsaturated Polyester Reinforced with (Glass and Rock Wool Fiber) under the Influence of Chemical Solutions

Abstract

In this research, the adhesive wear of a composite material consisting of unsaturated polyester has been studied as a matrix material reinforced by glass fiber and rock wool fibers. The wear rate property is compared in the normal condition and after immersion in (NaOH) and (HCl) solutions at normality (0.3N) and the laboratory temperature (25 oC) for 30 (days) and with a fixed volume fraction of (20%). The results showed that the wear rate decreased with increasing number of reinforcement layers before and after immersion and for all samples. However, it is noted that immersion in chemical solutions leads to an increase in wear rate compared that of the normal condition and for all samples.
