Specialists at the Reshetnev Siberian State University of Sciences and Technologies, in the Russian city of Krasnoyarsk, have developed antenna reflectors made of carbon fiber composite, a plastic material reinforced with carbon fibres.

The university announced that the antenna will be in great demand from the space and missile industries sector.

The university stated that this development is intended for use in the space sector, drone systems, and radar devices.

She said that antennas made of composite materials outperform their traditional metal counterparts in some critical criteria for the space sector, as carbon fibers, like composite materials, are characterized by high rigidity with very low density, as well as a coefficient of thermal expansion close to zero and resistance to cosmic radiation.

According to the university, this property of carbon fiber ensures the stability of the shape of the antenna reflector under sharp temperature fluctuations, ranging between -150 and +150 degrees Celsius.
She said: “The carbon fiber antenna reflector solves two main problems. The first is to reduce the weight of the spacecraft, knowing that every kilogram in orbit costs a lot of money, and the second is to maintain shape stability under temperature fluctuations. The development has been requested by the rocket and space industries sector.”

The university added: “Graduate students at the university received a certificate of accreditation from the Rasmach Mechanical Engineering Company, and the certificate was signed by the chief engineer of information and computing systems production.”
