FIELD: chemistry.
SUBSTANCE: invention relates to a prepreg for slip coats applied by means of fusion of structural materials onto metal surfaces by means of a laser beam. Prepreg is made from fabric of polyamide fibre impregnated with a mixture of high-molecular epoxy diane resin with molecular weight from 1000 to 3500 (A), triethanolamine titanate (B), boric anhydride (B) and coking petroleum pitch (D) in ratio, wt. parts, A:B:C:D 80:5:5:10 to 20:25:15:40, dissolved in ethyl cellosolve to concentration providing application of 20 % to 50 % of dry mixture on weight of prepreg.
EFFECT: higher hardness, wear resistance, antifriction properties, heat resistance and other physical and mechanical properties of coatings applied using the proposed prepreg.
