Abstract: This paper deals with the wear resistances of a composite material consisting of ultra-high molecular weight polyethylene (PE-UHMW) and high density polyethylene (PE-HD) reinforced with carbon nanotubes (CNTs). The optimum filling content of CNTs was between 0.2 and 2phr. The effect of pre-treating methods and CNTs in boiling nitric acid on the wear resistance was studied. The wear tests were performed in a ball-on-prism tribometer with the composite against two types of polished steel (austenitic X5CrNi18-10 and martensitic 100Cr6). It was showed that CNTs can improve the wear performance of PE-UHMW/PE-HD composites. The specific wear rate of composites decreased with increasing CNTs Content. The nanotubes can be dispersed in the matrix, however, some aggregates occurred. Further work is needed to improve the homogeneity of the nanotubes in the matrix.
