FIELD: epoxy.
SUBSTANCE: invention relates to the development of a thermosetting epoxy binder processed into a polymer composite material (PCM) using injection technologies with a molding temperature of up to 150°C, for the manufacture of structures, including large-sized ones. Thermosetting binder comprises the following ratio of components, parts by weight: ED-22 - 10-80; N,N,N',N'-tetraglycidyl-4,4'-diaminodiphenylmethane - 20-90; 2-methylimidazole - 1.0; resorcinol - 1.3; methylendic anhydride - 103.2-160.5.
EFFECT: increase in the glass transition temperature of the binder while maintaining a low viscosity of the binder.
