FIELD: chemistry.
SUBSTANCE: invention relates to constructive composite materials and can be used in construction, and in aerospace equipment. A solidified prepreg includes a structural layer of electrically conductive fibres and the first external layer of thermoactive resin, with the resin layer including thermoplastic particles and glassy carbon particles.
EFFECT: prepreg provides higher electrical conductivity, mechanical properties and resistance to damage, caused by strikes of lightning.
