FIELD: chemistry.
SUBSTANCE: prepreg contains a fiber-reinforced curable resin, wherein the prepreg contains electrically conductive particles in the range of 0.5 to 10 wt %, based on the resin. Electro-conductive particles include graphite in a potato form. The composite used, for example, as an aircraft component, is based on a prepreg and includes a fiber-reinforced cured epoxy resin and an electro-conductive particle. The composite contains an electro-conductive particle that includes graphite in a potato form. The curable epoxy resin comprises a reinforcing agent polyamide and graphite in a potato form.
EFFECT: preparing prepregs and composites based on prepregs with improved properties, in particular with increased electro-conductivity and increased mechanical properties.
