摘要
Ultra-high molecular weight polyethylene (UHMWPE) composites filled with high density polyethylene (HDPE) (up to 20 vol.%) and styrene-butadiene-styrene triblock copolymer (SBS) (up to 7 vol.%) were prepared by extrusion and subsequently hot press-molding. Based on the results of tensile and sliding wear tests, the tensile and tribological behavior of these materials was investigated. A synergistic effect of the incorporated HDPE and SBS is reported. The lowest friction coefficient and wear was obtained for the composition of UHMWPE with 10 vol.% HDPE and 5 vol.% SBS. The scanning electron microscopy (SEM) observation revealed that this hybrid reinforcement could be interpreted in terms of a positive rolling effect of the particles between the two sliding surfaces.
