AbstractThe current investigation is interested by study of the wear phenomenon for two polymeric materials (Epoxy and Unsaturated polyester) resins, the prepared specimens were tested at room temperature by using two different loads(10,20)N for various testing times with different sliding distances. The resulted wear rates were calculated for each sample apart with. Variation the previous variables. To produce more precise idea about the wear characteristics of both above materials when immersed them in water environment, the study of wear rates was carried out for different immersion times at different temperatures when the above mentioned variables were fixed. It was found after comparing the results which obtained from the wear test in air that
Epoxy resin undergoes higher wear rates than unsaturated polyester resin in general with variation the testing parameters, while the results of immersion in water which acts as plasticizing factor for polymers exhibited different effect on the wear behavior of the materials under study.
