METHOD FOR PRODUCING CARBON COMPOSITE MATERIAL, AND CARBON COMPOSITE MATERIAL

PROBLEM TO BE SOLVED: To provide a new method for producing a carbon composite material capable of reducing cost, and a carbon composite material.SOLUTION: By a component removal step, a carbon-containing material 11 consisting of a carbon-containing compound, alloy or non-equilibrium alloy is immersed into a metal bath 12 having a solidification point lower than the melting point of the carbon-containing material 11, and in which temperature is controlled to the one lower than the minimum value of the liquidus temperature in a compositional variation range in which the other main component other than the carbon is reduced from the carbon-containing material 11 to reduce the carbon, thus the other main component other than the carbon is selectively eluted into the metallic bath 12 to obtain a carbon member having microgaps. Further, cooling is performed in a state where the component of the metal bath 12 is present in the microgaps of the carbon member, and the component of the metal bath 12 is solidified to obtain a composite material in which the carbon and the component of the solidified metal bath 12 are compounded.SELECTED DRAWING: Figure 3 【課題】コストを低減することができる、新たな炭素複合材料の製造方法および炭素複合材料を提供する。【解決手段】脱成分工程により、炭素を含む化合物、合金または非平衡合金から成る炭素含有材料１１を、この炭素含有材料１１の融点よりも低い凝固点を有し、炭素含有材料１１から炭素以外の他の主成分が減少して炭素に至るまでの組成変動範囲内における液相線温度の最小値よりも低い温度に制御された金属浴１２に浸すことにより、炭素以外の他の主成分を選択的に金属浴１２内に溶出させて、微小間隙を有する炭素部材を得る。さらに、炭素部材の微小間隙に金属浴１２の成分が存在する状態で冷却し、金属浴１２の成分を固化することにより、炭素と固化した金属浴１２の成分とが複合した炭素複合材料を得る。【選択図】図３
