Abstract (en)
The method involves processing a pulverulent composition having carbon powder and thermoplastic binder at a temperature above a melting point of the binder to obtain a mixture having the powder and the binder. The mixture is optically milled and sieved and is compression molded to provide a desired shape. The shaped mixture is thermally treated at the temperature above the point and below a decomposition temperature of the binder. An independent claim is also included for a carbon brush.
