V. L. Strakhov, A. A. Filipenko, A. V. Ostrik, A. B. Mitkevich, Vl. O. Kaledin, and M. N. Slitkov UDC 681.3.06:678.01 A complex mathematical model of interaction of composite polymer materials (CMs) with radiations of different nature and a gas flow is developed. The model permits allowance for a set of such physicochemical phenomena as volumetric radiation absorption, pyrolysis of the organic components of the material, filtration of gaseous pyrolysis products in the pores of the subsurface layer, and the corresponding change in the composition and properties of the material in the subsurface layer. Based on the model, a computational system for calculating the parameters of interaction of CM products with radiation and a gas flow is created in accordance with advanced principles of object-oriented programming.
