MANUFACTURING METHOD OF CERAMIC COMPOSITE MATERIAL, AND CERAMIC COMPOSITE MATERIAL
To provide a manufacturing method of a ceramic composite material in which strength can be prevented from decreasing due to cutting of a ceramic fiber and a ceramic composite material with a smooth surface can be obtained, and the ceramic composite material.SOLUTION: The manufacturing method of the ceramic composite material includes: an impregnation step for obtaining an impregnated body 3 by impregnating a solution or slurry containing a ceramic precursor 1a in gaps between aggregates 2 that contain ceramic fibers 4; a firing step for obtaining a fired body 8 having the aggregates 2 and ceramic matrices 1b filled in the gaps between the aggregates 2, by curing and firing the impregnated body 3; and a cleaning step for removing a fired product 10 of the ceramic precursor formed on a surface of the fired body 8 by colliding a composite particle that contains an elastic body made of an organic substance and an abrasive made of the same compound as the ceramic fibers 4 against the surface of the fired body 8, in which at the cleaning step, a centrifugal blasting machine is used that injects the composite particle by using a centrifugal force generated due to rotation of a blade.SELECTED DRAWING: Figure 1
【課題】セラミック繊維が切断されることによる強度の低下を防止することができ、平滑な表面を有するセラミック複合材を得ることができるセラミック複合材の製造方法及びセラミック複合材を提供する。【解決手段】セラミック複合材の製造方法は、セラミック前駆体１ａを含む溶液又はスラリーを、セラミック繊維４を含む骨材２の隙間に含浸させて含浸体３を得る含浸工程と、含浸体３を硬化・焼成して、骨材２と、骨材２の隙間に充填されたセラミックマトリックス１ｂと、を有する焼成体８を得る焼成工程と、焼成体８の表面に、有機物からなる弾性体と、セラミック繊維４と同一の化合物からなる砥粒と、を含有する複合粒子を衝突させ、焼成体８の表面に形成されたセラミック前駆体の焼成物１０を除去する清浄化工程と、を有し、清浄化工程は、羽根の回転を利用した遠心力により前記複合粒子を噴射する遠心式ブラスト機を用いる。【選択図】図１
