The results of the elastic-strength properties of PCM, orderly reinforced with basalt-carbon fabrics, exposed for 12 months in an open polygon in a sharply continental climate for the impact of natural climatic factors on the basis of the Center for Collective Use of the Federal Research Center of the Yakutsk Scientific Center of the Siberian Branch of the Russian Academy of Sciences in Yakutsk, are presented.

The objects of study in this work were polymer composite materials based on polytetrafluoroethylene (PTFE) with fillers such as kaolin Al4[Si4O10](OH)8, carbon nanotubes (CNTs), and carbon fiber (CF). Filler modification methods were used, such as mechanical activation, ultrasonic (US) dispersion, and hybrid filling. The results of mechanical and tribological characteristics of new PCM compositions based on PTFE are presented. It has been established that the wear resistance of composites, compared to the wear resistance of the original PTFE, increases from 315 to 1090 times, depending on the content and type of filler.
