FIELD: chemistry.
SUBSTANCE: invention relates to preparation of epoxy binder for construction polymer composite materials based on carbon fibre filler, which can be used in aviation, space, machine- and shipbuilding industries, as well as other industries. The binder contains the following (pts.wt): epoxy-novolak resin 24-35, nitrogen-containing epoxy resin 27-32, hardener - 4,4'-diaminodiphenylsulphone 30-32, diglycidyl ether of diethyleneglycol 5-10 and a product of condensing glycol with dimethyterephthalate 2-5. The prepreg contains the following (in wt %): said epoxy binder 30-50 and fibrous filler - carbon bundles, tapes, fabric 50-70.
EFFECT: invention enables to obtain composite material and article with good strength properties, high crack resistance and impact viscosity.
