Abstract

In this study, the wear behavior of UHMWPE based hybrid composites reinforced with short carbon fibers and silica nano-particles at room temperature were investigated. The composite samples were fabricated by melt mixing process using the paraffin oil in order to overcome high viscosity of the polymer matrix. Finally, the wear tests were performed. The results of wear tests showed that the weight loss of the composite decreases noticeably in the presence of carbon fibers. It was also shown that the effect of nano-particles depends on their weight percent. The surfaces of the composite samples after the wear tests were investigated using a scanning electron microscope (SEM).
