PROBLEM TO BE SOLVED: To provide a method and a device for suppressing a generation of a crack inside a ceramic matrix composite material. SOLUTION: An assembled body(42) unable to be separated includes a main body(80) having a first face(82) and a second face(88). The main body(80) contains a ceramic matrix composite material with an oxide having a first given ductility as a substrate. The assembled body (42) further contains a patch (150) to be adhered to at least one of the first face (82) and the second face (88) by piling up a crack (128) spreading to the main body (80) between the first face (82) and the second face (88) at least on a part of an edge part (134) of the crack (128). The patch (150) contains a second material having a second predetermined ductility larger than the first ductility. COPYRIGHT: (C)2005,JPO&NCIPI |
