PURPOSE:To provide a carbon.metal composite material having a flexual strength and abrasion resistance by compounding a carbon raw material with metallic fibers oriented in one direction and at least partially coated with a different kind of material and the powder of a metal having a carbide-producing inclination smaller than that of the metal fiber. CONSTITUTION:One part or all of the surface of metal fibers (e.g. stainless steel fibers) are coated with a different kind of material (e.g. nickel). The metal fibers and the powder of a metal (e.g. copper powder having a carbide-producing inclination smaller than that of the metal fiber are mixed with a carbon raw material (e.g. self-sintering mesophase powder) and subsequently treated with a magnetic field of >= several ten thousand gauss, etc., to orient the metal fibers in one direction. the composition is molded and carbonized by a conventional method to prepare a carbon.metal composite material. The carbon.metal composite material is suitably used for pantograph sliding plates for trains, etc. |
