A process for producing a composite graphite material in a molded form having high density and tensile strength as well as impermeability, comprising the steps of mixing expanded graphite material with oxidized graphite material as the binder and compression molding the resulting mixture. In one embodiment, this invention relates to the composite graphite material produced by said process.

Composites of oxidized graphite material and expanded graphite material

A process for the preparation of a carbon-metal composite material for mechanical sliding members, comprising impregnating a carbon substrate with an alloy comprising copper, nickel or a copper-nickel as a base metal and at least one of titanium, zirconium and silicon as a wetting agent for the carbon. In one embodiment, the alloy further comprises at least one of a third component such as tin, antimony, zinc, manganese, iron, chromium, lead, magnesium and phosphorus.
