Abstract: The mathematical model and numerical method to solving the problems of heat state of majority composites in conditions of an appreciably unsteady high-thermal stressing are offered. Its base on the identification of the decomposition composites rule. This rule has been obtained and let to exclude chemical kinetics in a region of the decomposition in problems about heat state of the composition. Analysis of the numerical results proves this approach to modeling of heat state composites to be a proper one.

Keywords: composite, fine-fibred filler, resin binder, heat and mass transfer, mathematical modeling, numerical methods.
