Abstract

In the present work, the thermophysical and physicomechanical characteristics of a molten epoxy resin system VSE-62, developed in SIC «Kurchatov Institute» – VIAM, are considered. The value of the glass transition temperature of the system, the kinetic parameters of the curing process with a different speed of the heating, the plot of the gelation time and flexural strength are given. The results of rheological tests in isothermal and dynamical modes are shown. The low viscosity of the system and long-term viability at high temperatures allows it to be used for the manufacture of various polymer composite materials by resin transfer moulding and vacuum assisted resin transfer moulding.
