Russian Scientists Create New Protective Composite for Aerospace
A scientific team from the NUST MISIS Research Center “Structural Ceramic Materials” comprised of Veronika Suvorova, Andrey Nepapushev and Dmitry Moskovskikh has developed a new composite material based on hafnium carbonitride, which is resistant both to high temperature and oxidation. According to him, their material can be applied during the production of the critical assembly units of the rocket-space and other perspective equipment. The segments of the constructions made of the new composite will provide effective heat protection in the points of full flow braking that experience the highest thermal load, the creators explained. The scientists explained that they have synthesized hafnium carbonitride by burning a mixture of hafnium and carbon in a nitrogen atmosphere, and used spark plasma sintering to produce the volumetric material. According to the researchers, this method provides a simple, fast and energy-efficient approach that is suitable for industrial production. The study was carried out within the framework of the Russian Science Foundation (RSF) Grant No. 19-79-10280. At the next stage, the research team intends to work out the production technology from the new composite of various construction elements operated in high-speed gas flows.
