Research of the tribological properties of composite polymer materials during the breaking-in period

Results of research and development of composite polymer materials are presented. The aim of this work was the study and development of new composite polymer materials with optimal performance properties for the working bodies of machines and mechanisms. The surface grinding of the samples was carried out using an eccentric rotary brush according to the procedure previously presented by the authors. Tribological properties of polymeric materials and coatings were determined on a tribometer. The results of the study showed that the degree of influence of fillers on the strength and antifriction properties of composite polymer materials depends on the type and nature of the filler and binder.
