Abstract

Experimental and computational results of tribotechnical tests of polymer composites based on polytetrafluoroethylene and UVIS-AK-P discrete carbon fibers are presented. The PV factor is determined in the dry friction mode at a sliding speed of 0,2 m/s. Using the "steel disk — polymer disk" mathematical friction model, the maximum load was determined taking into account the allowable temperature of 120 °С for the friction surfaces of the materials under study. Keywords: polytetrafluoroethylene, wear resistance, friction coefficient, wear rate, carbon fiber. ppavlina@yandex.ru, markovamusya@mail.ru, roman_tikhon@mail.ru
