MOLDING METHOD OF CERAMIC BASE COMPOSITE
To mold a high quality ceramic base composite material by suitably impregnating the same with molten silicon and suppressing strength deterioration.SOLUTION: A method of molding a ceramic matrix composite material in which a ceramic matrix composite material is formed by impregnating it with molten silicon comprises steps of: laminating and curing prepregs in which reinforcing fibers and a matrix impregnated with the molten silicon to form a cured laminate; carbonizing the formed cured laminate to form an impregnation path in the cured laminate; and impregnating the cured laminate on which the impregnation path is formed with the molten silicon are carried out, and the base material resin contained in the matrix contains at least a benzoxazine resin.SELECTED DRAWING: Figure 2
【課題】溶融ケイ素を好適に含浸させて、強度低下を抑制し、高品質なセラミックス基複合材を成形する。【解決手段】溶融ケイ素を含浸させてセラミックス基複合材を成形するセラミックス基複合材の成形方法において、強化繊維と、前記溶融ケイ素が含浸するマトリックスとが一体となったプリプレグを積層及び硬化して、積層硬化体を形成するステップと、形成した前記積層硬化体を炭化させて、前記積層硬化体に含浸経路を形成するステップと、前記含浸経路が形成された前記積層硬化体に、前記溶融ケイ素を含浸させるステップと、を実行しており、前記マトリックスに含まれる母材樹脂は、少なくともベンゾオキサジン樹脂を含む。【選択図】図２
