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.
Claims4
A process of producing a composite material comprising the steps of:
- Adding a solvent to a mixture comprised of graphite and a binder to form a pasty mixture, wherein said solvent is added in an amount of 50 to 65 wt. % of the total weight;
- and
- Spraying said pasty mixture onto a three dimensional continuum of a porous metal, filling pores of said continuum of said porous metal, and then subjecting said continuum to volatilization of nonessential solvent.
