| Summary: | Title screen The development of new high-strength high-temperature thermoplastics opens up prospects for the creation of new types of polymer-polymer friction pairs. However, due to the low thermal conductivity of mated thermoplastic polymers, the frictional heat is localized in the tribocontact region. This fact exerts a significant effect on the physical and mechanical properties of the polymers and on their wear resistance. Taking into account the data of previous experimental studies, a model of the friction process and wear is developed, implemented, and verified as applied to the creation of a UHMWPE–PEEK polymer-polymer friction pair. In order to ensure the heat removal, it is proposed to use polymer composites in which, owing to the introduction of heat-conducting inclusions, the thermal conductivity increases. In addition, the degree of degradation of their strength properties caused by the frictional heating decreases, and, in turn, the wear rate decreases. The model developed was verified by the data of tribological tests of samples fabricated by the 3D-printing Текстовый файл AM_Agreement |
