Scientists create a material that protects satellites from cosmic rays


Professor at the University’s Department of Materials, Oleg Hasanov, said that the composite material created by Russian scientists is lighter than its foreign counterparts and is able to withstand the difference in temperature from minus 200 degrees Celsius to 200 degrees Celsius above zero, as well as the strong mechanical pressure affecting it.

“We have devised a technology based on a lightweight aluminum compound with the addition of nanoparticles and sub-microns, ceramic and tungsten components that are refractory,” he explained.

The compound differs from other materials by its non-porous structure (without pores) and by its homogeneous structure, as well as by a uniform distribution of its refractory components on the surface of a rapidly melting matrix, yet the material remains light, which is important for satellites and other space devices.

The purpose of the new composite material is to protect satellites from ionizing radiation currents, neutrons, electrons, ions and gamma rays, and an alloy of aluminum and magnesium forms 65% of the composite material that also includes boron carbide (to protect against neutrons) and tungsten nanoparticles (to protect against gamma rays).

It is reported that the new composite material production technology has obtained a patent. Scientists at Tomsk University intend to present it to engineers in the facilities of the Russian Cosmos Space Corporation, to be used later in designing devices that protect satellites from cosmic rays.
