Scientists from the Rosatom State Corporation have developed an innovative carbon fiber designed for use in the space industry. The material is characterized by high rigidity, the ability to withstand significant loads, and resistance to sudden temperature changes. It has no analogues in Russia.
Carbon fiber consists of thin filaments with low specific gravity and high thermal conductivity, and also has a near-zero coefficient of thermal expansion. These characteristics allow the new material to be used to create new generation space products, including orbital structures made of polymer composite materials up to 200 meters long.
The development of carbon fiber is based on special preparation of pitches obtained from oil refining and coal coking residues. It is expected that the unique properties of the new material will be in demand in the production of various space devices, such as reflectors for satellite systems, body elements and radiator coolers for space stations, as well as heat dissipation systems based on carbon-carbon composite materials with high thermal conductivity.
