Abstract

The finite difference and finite elements methods are regarded for mathematic simulation of thermoset curing processes on the example of epoxy resin and amine hardener. The finite difference method was used to simulation of flat layer curing and simultaneous solution of heat transfer and chemical interaction problem. The finite element method was used for simultaneous three-dimensional numerical solution of heat transfer, chemical interaction and stress-strain problems during curing of complex-shape samples. The verified kinetics model obtained from differential scanning calorimetry was used. The literature data of the parameters of heat transfer, chemical shrinkage and thermal expansion were used for calculations.
