Beschreibung
Zusammenfassung:	FIELD: rocketry, in particular, binding compositions for impregnation of reinforcing materials (glass fibers, glass belts) at armouring of solid propellant charges by the winding method. ^ SUBSTANCE: offered is a binding composition containing epoxydianil resin with molecular mass 390-430, expoxydianil resin with molecular mass 480-540, epoxydianil resin, product of condensation of trimethylpropane with epilchlorohydrin, isomethyltetrahydrophtal anhydride. Solidified composition of the binder with a high heat resistance (up to 145 C) is obtained. ^ EFFECT: enhanced resistance of articles to aerodynamic heating. ^ 2 tbl
