FIELD: space materials science.
SUBSTANCE: invention relates to the development of materials that provide protection from space radiation, including electron, proton, gamma and neutron radiation. Composite material for protection against ionizing radiation includes supermolecular polyethylene and fillers, in the following ratio, wt.%: supermolecular polyethylene (SMPE) 35-50; bismuth oxide Bi2O3 37.5-47.5; boron carbide B4C 12.5-17.5.
EFFECT: invention makes it possible to obtain a composite material for protection against ionizing radiation, which has improved physical and mechanical properties.
