METHOD FOR PRODUCING CARBON FIBER-REINFORCED SILICON CARBIDE-BASED COMPOSITE MATERIAL, AND CARBON FIBER-REINFORCED SILICON CARBIDE-BASED COMPOSITE MATERIAL
To provide a method for producing a carbon fiber-reinforced silicon carbide-based composite material, capable of producing the carbon fiber-reinforced silicon carbide-based composite material that is excellent in moldability, has high mechanical strength, and is excellent in thermal conductivity; and to provide a carbon fiber-reinforced silicon carbide-based composite material.SOLUTION: A method for producing a carbon fiber-reinforced silicon carbide-based composite material includes: molding a carbon fiber-reinforced plastic using a sheet molding compound that comprises a carbon fiber and a matrix resin; calcinating the carbon fiber-reinforced plastic to make a carbon fiber-reinforced carbon composite material; and melt-impregnating a metal Si to the carbon fiber-reinforced carbon composite material. In the carbon fiber-reinforced silicon carbide-based composite material, a cross-section obtained by cutting the composite material in a pressure direction at the time of molding has stripe-shaped impregnated parts comprising one or both of the metal Si and silicon carbide, and the stripes in the stripe-shaped impregnated parts are stretched in a random direction.SELECTED DRAWING: Figure 1
【課題】成形性に優れ、機械強度が高く、熱伝導性に優れる炭素繊維強化炭化ケイ素系複合材を製造できる炭素繊維強化炭化ケイ素系複合材の製造方法、及び炭素繊維強化炭化ケイ素系複合材を提供する。【解決手段】炭素繊維及びマトリックス樹脂を含有するシートモールディングコンパウンドを用いて炭素繊維強化プラスチックを成形し、前記炭素繊維強化プラスチックを焼成して炭素繊維強化炭素複合材とし、前記炭素繊維強化炭素複合材に金属Ｓｉを溶融含浸する、炭素繊維強化炭化ケイ素系複合材の製造方法。成形時の加圧方向に切断した断面に金属Ｓｉ及び炭化ケイ素のいずれか一方又は両方を含む筋状の含浸部分があり、前記筋状の含浸部分の筋の方向がランダムになっている、炭素繊維強化炭化ケイ素系複合材。【選択図】図１
