The influence of deformation and temperature on the value of the kinetic parameter—the activation energy of the plastic flow of glass-basalt plastic—was studied. The glass basalt plastic samples differed in the ratio of components in the binding compound. In the process of studying the thermal activation properties, it was shown that the activation energy of the plastic flow of a material is an indirect characteristic of thermal resistance, i.e. in a certain range of heating temperatures of the material at the same values of applied forces, a change in activation energy occurs as a consequence of structural changes in the binder. The purpose of this work was to determine the thermal activation parameters of glass basalt plastic based on epoxy resin, a curing compound - isomethyltetrahydrophthalic anhydride (IsoMTPHA) and a flexibilizer - carboxylate rubber SKN-26-1A. Studying the relationship between mechanical characteristics and physical properties of a substance is the basis for promising methods for predicting kinetic parameters in a wide temperature range. As a result of the study of creep kinetics, the following results were obtained: 1) the influence of the composition of the glass-basalt-plastic binder compound on the value of the initial activation energy of the plastic flow of the material has been established Q0 in a wide range (2.68- 2.445 K) of loading temperatures was discovered; 2) a regression analysis method is proposed for statistical processing of the obtained Q0 values. The use of the temperature jump method is advisable at any temperature where inelastic deformation is observed. The value of the activation energy of plastic flow correlates with the magnitude of internal stresses, the flow rate of the material, and can be a characteristic of the thermal resistance of the material.
