METHOD FOR PRODUCING CARBON COMPOSITE MATERIAL, AND CARBON COMPOSITE MATERIAL

Document Type and Number:

WIPO Patent Application WO/2017/149887

Kind Code:

A1

Abstract:

[Problem] To provide: a novel method for producing a carbon composite material which makes it possible to reduce costs; and a carbon composite material. [Solution] By using a component removal step, the present invention obtains a carbon member having fine pores by: immersing a carbon-containing material 11 comprising a carbon-containing compound, alloy or non-equilibrium alloy in a metal bath 12 having a solidification point that is lower than the melting point of the carbon-containing material 11, and controlled to a lower temperature than the minimum liquidus temperature in the compositional variation range extending until carbon is obtained from the carbon-containing material 11 by decreasing the principal components thereof other than carbon; and as a result, selectively eluting the principal components other than carbon into the metal bath 12. Furthermore, by cooling while a component from the metal bath 12 is present in the fine pores of the carbon member, and solidifying the metal bath 12 component, it is possible to obtain a carbon composite member that combines carbon and the solidified metal bath 12 component.
