DEVELOPMENT OF ELEMENTS OF A REUSABLE HEAT SHIELD FROM A CARBON–CERAMIC COMPOSITE MATERIAL. 2. THERMAL TESTS OF SPECIMENS OF THE MATERIAL

This paper presents the results of testing specimens of porous carbon–ceramic composite materials on the hightemperature gas-dynamic plasmatron VGU-4. The structure of carbon–ceramic composite materials of various densities before and after tests has been investigated. It has been shown that the porosity of such a material infl uences the process of its thermal destruction and ablation in a high-enthalpy gas fl ow
