The article presents the dependence of the physical-mechanical and tribological characteristics on the manufacturing technology of polymer composite materials based on PTFE of PN grade and carbon fibers of UVIS-AK-P brand produced by OOO UVIKOM. Modification of polytetrafluoroethylene with a carbon filler provides low friction coefficient, and the wear resistance of composites increases by 77–2024 times in comparison with an unfilled polymer. The technological method of introducing filler through a concentrate applied in the present work has resulted in an improvement of the operational characteristics of composite materials compared to the initial polymer. Various technological approaches based on the methods of joint mechanical-chemical activation of components and milling of a polymer mixture, which contribute to an increase in operational characteristics, have been considered. The dependence of the operational properties of composite materials on the amount of filler in the polymer mass has been analyzed.
