Abstract

The results of the determination of the thermal conductivity and heat capacity of epoxy material directly during its curing, are given. when the phase state changes. As an object of research, an epoxy formulation based on epoxy-diane resin and modified aliphatic polyamine was used. Thermophysical properties were determined for different degrees of conversion at room and elevated temperatures. Depending on the degree of conversion, the value of volumetric shrinkage and residual stresses were also evaluated. It was found that during the curing process (i.e., when the degree of conversion is changed), the heat capacity decreases by 32% and more than three times the thermal conductivity increase.
