The effect of carbon fibers (CF) of the Belum brand is explored from the standpoint of influencing the performance parameters and the structure of polymer composite materials (PCM) based on ultra-high molecular weight polyethylene (UHMWPE). It is established that composites having CF content in the amount of wt % exhibit the optimum set of properties. The wear resistance increases by a factor of 3.3, while the deformation and strength characteristics of the material remain at the level of unfilled UHMWPE. It is found that the creep of PCM having composition UHMWPE + 5 wt % Belum is two times less than that of the initial polymer. We also compared the physical and mechanical properties of material developed having unfilled UHMWPE and modified polytetrafluoroethylene (PTFE). It is shown that the creep of UHMWPE is 1.5 times less than the creep of PTFE. The creep in the composite based on UHMWPE is 13 times less than the creep of the composite based on PTFE.
