Abstract

A method for bench testing of a sample of a reusable composite material when exposed to high-intensity thermal and ionizing radiation has been proposed. The tests were carried out on a specialized laser bench under the influence of high-intensity energy fluxes. As a result of the experiment, we obtained a field of temperatures and displacements on the surface and in the depth of the heat-shielding material at different points of time. The validity of the proposed mathematical model is confirmed by many numerical experiments. The results of some experiments are given as functions of time, temperature, the thermal characteristics, the mass and linear velocities of the pyrolysis zone, the density and stagnation pressure of gases in this area, and the pressure distribution and the mass filtration rate in the resulting porous residue.
