FIELD: protective coatings. ^ SUBSTANCE: invention relates to field of manufacturing composite materials for aircraft equipment and may be, in particular, used for protection of aircraft parts and units disposed on fuselage against lightning damage. Coating comprises dielectric and conducting layers. The former is made from cured polymeric epoxide or polyamide matrix and the latter, based on high-strength carbon fibers, is made from two or more single layers of carbon tissue arranged at an angle between -30 and +60° to each other, in interfibrillar space of which polymeric epoxide or polyamide binder with decomposition temperature >=250°C is inserted. Binder contains uniformly distributed carbon particles of schungite (naturally occurring crystalline carbon substance with fulleroid structure and size 2-10 mum) in amount 5 to 40%. ^ EFFECT: enhanced lightning resistance and strength of coating, reduced manufacture expenses, and simplified manufacture process. ^ 2 tbl, 4 ex |
