Abstract
A method for repairing a target member including a ceramic matrix composite reinforced by ceramic fiber includes: a removal step of removing at least a part of a surface of the target member; an arrangement step of arranging a green body for repair which includes the ceramic fiber on a portion where the surface is removed in the removal step; an impregnation step of impregnating at least the portion of the target member where the green body for repair is disposed with slurry; and a sintering step of sintering the target member on which the green body for repair is disposed, after the impregnation step.

A method for repairing a target member including a ceramic matrix composite reinforced by ceramic fiber, the method comprising:
- a removal step of removing at least a part of a surface of the target member;
- an arrangement step of arranging a green body for repair which includes the ceramic fiber on a portion where the surface is removed in the removal step;
- an impregnation step of impregnating at least the portion of the target member where the green body for repair is disposed with slurry;
- and
- a sintering step of sintering the target member on which the green body for repair is disposed, after the impregnation step.
A ceramic matrix composite member comprising a ceramic matrix composite reinforced by ceramic fiber, comprising:
- a body portion;
- and
- a joint portion joined integrally to the body portion, the joint portion occupying a part of a surface of the ceramic matrix composite member,
- wherein, at least one of an extension direction of bundles of the ceramic fiber or an arrangement interval of bundles of the ceramic fiber is different, in the body portion and the joint portion.
A ceramic matrix composite member comprising a ceramic matrix composite reinforced by ceramic fiber, comprising:
- a body portion;
- and
- a joint portion joined integrally to the body portion, the joint portion occupying a part of a surface of the ceramic matrix composite member,
- wherein the body portion includes at least one hole extending toward an Side of the body portion from a boundary surface between the body portion and the joint portion, and the at least one hole is filled with a matrix of the ceramic matrix composite.
