FIELD: composite materials.
SUBSTANCE: invention relates to methods for producing fiber-reinforced composites. A method for producing fiber-reinforced composites is proposed, where fibrous reinforcing material is laid, and, through fibrous reinforcing material, a composition of curable epoxy resin is infused, containing alkylbenzoldiamine and additional aromatic amine, at a temperature in the range from 80 to 130°C, and right after the infusion of fibrous reinforcing material by the composition, the temperature is increased to a value in the range from 150 to 190°C.
EFFECT: proposed method provides for the production of fiber-reinforced composite materials and products with improved values of glass transition temperature in a dry state and mechanical characteristics.
