Аннотация:New polymer composite materials (PCMs) based on a mixture of phenol-formaldehyde and phthalide-containing phenol-formaldehyde resole-type binders reinforced with polyoxadiazole fiber have been obtained, and their tribological properties have been studied. The influence of the content of phthalide-containing phenol-formaldehyde polymer in a two-component mixture of binders on the hardness of the surface layer, tribological and thermofriction properties of PCM in various dry friction units on steel was studied. It has been shown that the resulting PCMs are superior in tribological and thermofriction properties to PCMs based on phenol-formaldehyde or phthalide-containing phenol-formaldehyde resole-type binders.
