FIELD: production of composite materials; aviation.
SUBSTANCE: invention relates to composite materials used in aerospace vehicles, and relates to pre-impregnated conductive composite sheet and method of its production. Method comprises steps of connecting a nanomaterial-containing composite sheet, a fiber-reinforced sheet and a resin system to form a composite sheet, heating the composite sheet, compaction of composite sheet and cooling of composite sheet with formation of pre-impregnated conductive composite sheet containing fiber-reinforced sheet and containing nanomaterial composite sheet, connected to the fiber-reinforced sheet, wherein the fiber-reinforced sheet and the nanomaterial-containing composite sheet are embedded in the resin system.
EFFECT: invention provides higher strength, reduced weight, protection against lightning and/or shielding of aircraft equipment and electronic equipment from external electromagnetic interference, providing long service life of various components of airborne vehicle.
