Abstract—It has been demonstrated that while using diethylene glycol as an active solvent, it is possible to
significantly decrease the viscosity of epoxy binders and, hence, to decrease the duration of impregnation irre-
spectively of the geometrical properties of the molded article. The results of the numerical simulation of the
impregnation rates of the fiberglass fabric of various weave patterns are given as a function of the geometrical
properties of the molded article. It is established that for a highly viscous binder the impregnation duration of
the integral panel is more than triple that of a flat one. The decrease in viscosity leads to the alignment of the
impregnability rates and the difference in time for flat and integral panels is not higher than 5%.
