Patent number: 12600678Abstract: Provided is a method for charging, with ceramic, open pores formed in a matrix of a ceramic matrix composite that includes the matrix and reinforcing fibers provided in the matrix. The ceramic comes to constitute the matrix. The method includes repeating the following steps (A) and (B) in a state where the ceramic matrix composite is arranged in a liquid material serving as a matrix material. At the step (A), the ceramic matrix composite is heated such that the liquid material is brought into a film-boiling state, and the ceramic derived from the liquid material is thereby generated in the open pores. At the step (B), the ceramic matrix composite is cooled until a temperature of the ceramic matrix composite becomes lower than a boiling point of the liquid material.Type: GrantFiled: December 3, 2021Date of Patent: April 14, 2026Assignee: IHI AEROSPACE CO., LTD.Inventors: Yuki Kubota, Michimasa Uda, Haruhiko Soeda, Takuya Aoki
