The effect of heat accumulation in the superficial layer of heat-shielding materials during the increase of its temperature was confirmed by an experimental approach. Experimentally, we confirmed the existence of emission of radiation energy which was not absorbed by a material by the surface of heat-shielding materials. We propose the method for the estimation of the temperature of the surface of a heat-shielding material with the use of the distributed fiber-optical gauge not demanding the application of the obturator.
