Аннотация:In the work new polymer composite materials reinforced with cotton fabric based on resol phenol-formaldehyde binder modified with dispersed polyethylene terephthalate were obtained. The obtained composites have lower values of the friction coefficient and wear compared to cotton textolites of tribotechnical purpose, widely used in industry, with dry friction on steel. A polymer composite material based on resol phenol-formaldehyde binder reinforced with polyethylene terephthalate fabric was obtained and its tribological properties were studied.
