FIELD: chemistry.
SUBSTANCE: epoxy binding agent includes a mixture of epoxy diane resin with one of epoxy resins, taken from the group N,N'-tetraglycidyl derivative of 3,3'-dichloro-4,4'-diaminodiphenylmethane, polyglycidyl derivative of low molecular phenolformaldehyde novolak, triglycidyl derivative of paraaminophenol, product of nucleophilic polycondensation of bis-(halogene aryl)sulphones with bisphenol with terminal hydroxyl groups with the molecular weight of 25000-45000 and vitrification temperature of 190-260°C and dicyandiamide.
EFFECT: increase of the soaking quality in the prepreg composition based on the claimed binding agent and fibrous filler, the product, made from the claimed prepreg, possessing increased strength and tensile modulus and modulus of compression.
