CERAMIC FIBER-REINFORCED CERAMIC COMPOSITE MATERIAL AND PRODUCTION METHOD THEREFOR
To provide a ceramic fiber-reinforced ceramic composite material having high strength and high thermal conductivity by suppressing generation of swelling or foams, and a production method therefor.SOLUTION: A ceramic fiber-reinforced ceramic composite material 7A is produced by steps of: slurry impregnating for obtaining a slurry impregnated body 4 by impregnating a slurry containing ceramic particles 3 and water in an aggregate 2 in which ceramic fibers 1 are aligned in one direction or two directions; drying for obtaining a dry body 5A by freeze drying the slurry impregnated body 4; and forming a matrix for forming a matrix by introducing a matrix raw material 8 between ceramic particles 3 after drying.SELECTED DRAWING: Figure 1
【課題】膨れや、気泡の発生を抑制することにより、強度が高く、熱伝導率の高いセラミック繊維強化セラミック複合材料及びその製造方法を提供する。【解決手段】セラミック繊維強化セラミック複合材料７Ａは、セラミック繊維１が１方向又は２方向に配向した骨材２に、セラミック粒子３と水とを含有するスラリーを含浸し、スラリー含浸体４を得るスラリー含浸工程と、スラリー含浸体４を凍結乾燥し乾燥体５Ａを得る乾燥工程と、乾燥工程の後にセラミック粒子３間にマトリックス原料８を導入しマトリックスを形成するマトリックス形成工程とで製造される。【選択図】図１
