FIELD: electrical engineering; materials for electrical machine brushes; electromechanical engineering and transport. SUBSTANCE: carbon filler of material is prepared by crushing carbon blanks containing in their composition soot, coke and/or artificial graphite, element graphite, and coke of high-temperature coal tar pitch. EFFECT: improved strength and mechanical endurance of electric brush material due to more homogeneous structure and low size of voids. 4 cl, 2 tbl
