NANOMODIFIED EPOXY COMPOSITE MATERIALS FOR METAL-POLYMER TRIBOSYSTEMS OF TRANSPORT VEHICLES

摘要

The influence of nanodispersed silver carbonate and microdispersed MoS _( 2 ) and Mg _( 3 ) Si _( 4 ) O _( 10 ) (OH) _( 2 ) fillers on the tribological properties of epoxy composites was investigated. Analysis of the curves of the dependence of temperature and friction coefficient of epoxy composites on the content of the modifier and fillers made it possible to set the optimal weight ratios of additives in a material with improved exploitation characteristics. The wear mechanism of epoxy composites has been substantiated. The process of formation of the lubricant film due to the synergistic interaction of nano- and microdispersed particles with the epoxy polymer was studied; it additionally increases the load capacity and reduces the mass intensity of the wear of composites.
