Due to the high specific surface area of nanoparticles, in comparison with micro-sized particles, a significant improvement in the consumer properties of polymer nanocomposites is achieved at relatively low concentrations of nanoscale fillers (up to 5%). Research and subsequent development of new polymer nanocomposites are of great scientific and practical interest, as they provide further development of promising high-performance technologies for restoring landing holes, increasing the post-repair life of basic parts and reliability and significantly reducing the cost of repairing agricultural machinery. The article describes the influence of metal nanoparticles on the thermophysical and mechanical properties of elastomers, presents the results of experimental studies of the deformation-strength and adhesive properties of a nanocomposite based on F-40 elastomer filled with nanoscale copper and aluminum particles as well as its optimal composition. Comparative data on the heat and heat resistance of the F - 40 elastomer and the nanocomposite based on it are presented.
