The aim of this research is to assess and develop a polymeric material consisting of a mixture of high-density polyethylene (HDPE) and ultra- high- molecular- weight polyethylene (UHMWPE) reinforced by carbon-nanotube (CNT) by optimizing the mixing concentration of the three constituents. This optimized mixture is accomplished by using a melt extruder-mixing process. An experimental evaluation for accurate assessment of the developed nanocomposite material characteristics is achieved by using a universal tensile test machine and a plint-tribometer pin-on-disc machine. Moreover, the hardness of the material surface and its surface topography are assessed by a hardness tester machine and SEM technique, respectively. Developed samples for testing are classified into two groups of nanocomposites. The first group is created through mixing two pure polymeric UHMWPE and HDPE with different mass ratios of each.
