FIELD: electric engineering. SUBSTANCE: carbon filler of material is made from noodle blanks that contain carbon black, coke and/or artificial graphite, natural graphite and coke of high-temperature coal pitch. This results in increased strength of material, its stability against wear due to more uniform structure having lesser pores. EFFECT: increased quality, increased functional capabilities of brushes, decreased cost of manufacturing. |
