Аннотация:The review summarizes and analyzes the results of research by scientists from the scientific school of Academician V. V. Korshak in the field of developing polymer composite materials of tribological design for dry friction units and studying their properties carried out under the guidance of Professor A. P. Krasnov in the XXI century. The regularities of affecting the chemical structure and molecular weight of polymers, type of filler, and friction conditions (temperature, environment) on the course of tribochemical processes, wear, and coefficient of friction were considered during the study of materials based on various classes of polymers (polyarylene ether ketones, polyarylates, polyamides, and phenol-formaldehyde resins).
