Zusammenfassung:	FIELD: construction engineering; mechanical engineering; rocketry; space engineering for fire safety of articles. ^ SUBSTANCE: proposed binder contains components at the following ratio, parts by mass: epoxy-dian resin, 100; aniline-phenol-formaldehyde resin used as hardening agent, 80-100; urethane prepolymer used as modifying agent, 50-65; 3,3'-dichloro-4,4'-diamino-diphenyl methane used as hardening agent, 8-15; 2,2'-bis(3,5-dibromo hydroxyphenyl) propane, 120-140; solvent, 225-290. Used as solvent is alcohol-acetone mixture at mass ratio of alcohol to acetone of 1:1. ^ EFFECT: reduction of gelatinization time; production of prepreg on base of this binder at high life time and difficultly combustible plastic at high ultimate strength. ^ 8 ex
