ABSTRACT:
An electroconductive composite material composed of a three-dimensional continuum of a porous metal with the pores filled with graphite and a resin, having a good heat resistance, wear resistance, strength and thermal conductivity, having a light weight, and particularly useful as electric armature brushes and other electric sliding elements.
A process of producing the composite material comprises the steps of: filling pores of a three-dimensional continuum of a porous metal with a pasty mixture composed of graphite, a binder, and a solvent; treating the continuum for volatilization of the solvent; and then, forming and heating the continuum.
