In this research, a non-reinforced epoxy and its composites which reinforced by fiber glass, polypropylene fiber and micro-silica oxide powder, with volume fraction (20%) were prepared, using a hand lay-up molding method. Impact strength, Surface hardness, and Bending strength tests were carried out for the specimens before and after immersion in tap water and ethanol. Before immersion, the results showed that adding fiber glass and polypropylene fiber to the polymer improved the mechanical properties while silica particles decreased it. On the other hand water absorption of the substance led to a negative effect on the mechanical properties of the composite material. The effect of ethanol was the highest.
