SINOPSIS

The results of a critical analysis of the state-of-the art in the area of the development and prospects of development of different kinds of heat-resistant carbonaceous composite materials (CCM), complex investigation of their structure and oxidation resistance are presented. Attention is focused on home-made CCMs with the aim of selecting a structural material for the parts and units of flying vehicles and new-generation propulsion systems operating in hypersonic flows of oxygen-containing plasma under simultaneously acting nonstationary mechanical and thermal loadings. The results of investigation of the oxidation resistance of the best of CCMs that demonstrated a complete loss of protective properties and the burning-out of the material at Tw > 1300°C even under the conditions of natural convection of air are presented. The necessity of introducing an additional layer with a more effective protective ability into the composition of the wall is shown. The possibilities of improving the service properties of the carrier material with the aid of high-temperature multifunctional coatings, being developed, are considered. The results of the work can be used in developing and designing thermally stressed elements of the structures of aerospace and rocket hardware.
