FIELD: chemistry.
SUBSTANCE: binder contains the following in wt %: epoxy component in form of a mixture of N,N,N'N'-tetraglycidyl-4,4'-diamino-3,3'-dichlorodiphenylene methane (42.8-45.5) and polyfunctional epoxy-novolak resin (18.3-19.5), hardener - 4,4'-diamino-diphenylesulphone (18.8-23) and N,N'-hexamethylene bismaleimide (15.3-16.2). The prepreg contains the following in wt %: binder - 17.0-51.4 and filler - 48.6-83.0. The article is made from the prepreg through hot shaping.
EFFECT: invention enables to obtain binder with high heat resistance and the prepreg and article made from said binder has high fracture viscosity.
