FIELD: production of laminated plastic used for manufacture of articles of machine-building and aircraft industries, including the manufacture of loose-running blades.
SUBSTANCE: the method consists in the fact that the carbon fibrous filler is impregnated by an epoxy binder and a prepreg is obtained. Then the prepregs are stacked and molded. At stacking a thermoplastic polyamide or polysulfonic film at the rate of 1-10 percent by mass by 100 percent by mass of the binder is placed between the layers of prepregs. The surface energy of the thermoplastic film makes up at least 50 mJ/sq.m.
EFFECT: enhanced resistance to impact loads and enhanced level of preservation of residual strength at a compression after an impact.
