MANUFACTURING METHOD OF CERAMIC MATRIX COMPOSITE MATERIAL
PROBLEM TO BE SOLVED: To provide a manufacturing method of ceramic matrix composite material capable of simplifying its manufacturing process, by which a product hardly causing strength reduction can be produced.SOLUTION: This invention provides a manufacturing method for a ceramic matrix composite material, in which the ceramic matrix composite material has woven fabrics 1 comprising a plurality of fiber bundles 2 and sizing material 4 coating the peripheries of the fiber bundles, and a matrix 3 disposed in the gaps between fibre bundles. The manufacturing method for the ceramic matrix composite material comprises an element assembly forming step which forms the element assemblies by impregnating the woven fabrics 1 with a polymer as precursor of the matrix 3, and a densification step in which the element assemblies are further impregnated with the polymer, and thereafter densified by calcination, in which the element assembly forming step includes an interface layer forming step which forms the interface layer 4 on the fiber bundles 2 by modification of the sizing material by heating the woven fabrics 1 under nitrogen atmosphere.SELECTED DRAWING: Figure 3
【課題】強度低下が生じにくく、かつ製造工程を簡単にすることが可能なセラミックス基複合材料の製造方法の提供。【解決手段】複数の繊維束２、及び繊維束の周囲を覆うサイジング材４を有する織布１と、繊維束同士の間の間隙に配置されたマトリックス３と、を有するセラミックス基複合材料の製造方法であって、織布１にマトリックス３の前駆体としてのポリマーを含浸させて素体を形成する素体形成工程と、素体にポリマーをさらに含浸させ、焼成する緻密化工程と、を含み、素体形成工程が、織布１を窒素雰囲気下で加熱することで、サイジング材を変性させて繊維束２に界面層４を形成する界面層形成工程を含むセラミックス基複合材料の製造方法。【選択図】図３
