FIELD: composite materials. SUBSTANCE: invention relates to manufacture of polymer composite materials based on epoxy resin reinforced by unidirectional fibrous filler. Invention aims at increasing specific impact elasticity and bursting stress upon static bend of reinforced composite material. Method is based on that, in addition to known operations involving impregnation of fibrous filler with epoxy resin, shaping, and hardening of preform, after impregnation, magnetic treatment is additionally performed for 0.8-1.8 s with magnetic field intensity 9000-11000 Oersted. Magnetic treatment of glass, carbon, and polycaproamide threads freshly impregnated with binder solves aim of invention. EFFECT: essentially increased strength of materials. 2 tbl, 1 dwg
