Abstract: A model for synthesizing a composite during combustion is proposed and numerically investigated. It is assumed that a set of chemical transformations can be described by a kinetic scheme with two total parallel reactions. One of the reactions corresponds to the matrix synthesis, and the other one to the inclusion synthesis. It is taken into account that the mixture components melt in a certain temperature range rather than at a fixed melting point. The possibility of the reaction front propagation in a self-oscillating mode is shown. The critical values of the parameters that separate the stationary and self-oscillating modes of the reaction front propagation are revealed. Computational results in extreme cases correspond to known theoretical concepts.

Keywords: composite synthesis, solid-phase combustion, parallel reactions, two-phase zone, self-oscillating mode.
