摘要

The abrasion resistance of composite materials obtained by varying the degree of impregnation of a nonwoven needle-punched fabric made from a mixture of polyethylene terephthalate fibers with linear densities of 0.22 and 0.66 tex with an aqueous polyurethane dispersion was investigated. Kinetic dependences of the mass reduction of the samples during abrasion on the degree of impregnation of the nonwoven fabric were obtained. A random change in the degree of wear was established. The mechanism of the behavior of the composite materials during abrasion depending on the degree of impregnation and the binder structure-formation process in the nonwoven fabric was described. A regression empirical model was developed to predict the mass reduction of the polishing material depending on the degree of impregnation and the duration of abrasive action.
