FIELD: chemistry.
SUBSTANCE: invention relates to epoxy binder for polymer composite materials of structural purposes and can be used in production of shells of revolution of “cocoon” type. Invention improves rheological properties of binder, prolongs life thereof and improves physical and mechanical characteristics of composite material based on polymer matrix and fibrous filler from aromatic polyamide of Armos type, and improves processability of binder due to reduced temperature and mixing time of binder.
EFFECT: invention consists in exclusion from formulation of epoxy binder UP-2217 powdered aromatic hardener Diamet-X and replacing it with an adduct of diethyl toluylene damine with aminophenol epoxy resin (liquid hardener XT-187B) at optimum concentration of 30 pts.wt.
