Development of Wear-Resistant Materials Based on Polytetrafluoroethylene and Carbon Fibers of UVIS-AK-P Brand

The present paper considers the influence of various technological approaches, based on the application of joint mechanochemical processing of composite components and ultrasonic action, on the performance of composites based on PTFE and discrete carbon fibers of UVIS-AK-P brand. It is established that the use of a certain method of energy deposition on the composite components for the complex enhancement of physical-mechanical and tribological properties depends on the concentration of carbon fibers (CF) in polymer matrix. As a result of the joint mechanoactivation treatment of the components in the planetary mill for 2 minutes, an improvement in physical-mechanical and tribotechnical properties of PTFE with CF concentration of 5 wt.% is observed. An improvement at concentration of 3 wt.% of CF is detected during ultrasonic treatment of PCM components.
