Применение катализаторов отверждения для регулирования анизотропии механических свойств стеклопластиков

Abstract

The article addresses the problem of influence unequal curing caused by the temperature gradient in the thickness of the material anisotropy on the strength properties of PCM. The authors studied the influence of the catalysts for curing epoxy binder EDT-69N to be used for the manufacture of multilayer polymer composite materials (PCM). According to the dielectric spectroscopy proved ac-celerating effect of selected compounds on the curing process of epoxy binder EDT-69N with the forming of fiberglass. The authors show the possibility of regulating the process of curing with the aid of catalysts to reduce the influence of temperature gradient on the anisotropy of strength properties of the matrix in the manufacture of PCM.
