FIELD: chemistry.
SUBSTANCE: heat-resistant radar-absorbing coating on mineral fibres is obtained by applying an electroconductive carbon layer on mineral fibres with diameter of 4…9 mcm. The carbon coating is obtained from flat carbon particles that are chemically activated in sulphuric acid and nitric acid, said particles having thickness of 4.0…7.0 nm and diameter in the layer plane of 800…3000 nm.
EFFECT: high heat resistance of the coating, wider operating temperature range and wider range of possible applications of the radar-absorbing coating while maintaining efficiency of absorbing electromagnetic radiation.
