Studying the Effect of Polymeric Fibers and Powders Addition on the Sliding Wear of Unsaturated Polyester Resin

Abstract

The current investigation is interested by study the effect of polymer fibers and powders such as, High Density Poly Ethylene (HDPE) fibers, Poly Vinyl Chloride (PVC) and Unsaturated Polyester (UPE) fillers, weight fraction on the sliding wear behavior of Unsaturated polyester resin, under dry sliding conditions, such as applied load, sliding speed at room temperature. The wear rate were investigated according to (ASTM-D 5963) using pin on disc machine to present the composite tribological behavior. The results showed that, when the loads increase, wear rates were enhanced when all types reinforcement materials was increased up to (3.4wt.%) and then decreased after (12.2wt.%), (9.5wt.%) for (HDPE) fibers and (PVC) powder, respectively. In the case of the sliding speed increase, the wear rate of (UPE) powder composite was decreased with powder increase, While The improvements in the wear are decrease when the additions of (HDPE) fibers and (PVC) powder to unsaturated polyester resin was increased up to (9.5 wt.%).
