Abstract: A production method of a ceramic matrix composite is consisted of: forming a ceramic compact including one or more of a reinforcement fiber and a powder, each including SiC; attaching an ingot of a ternary or more multicomponent Si alloy including Y onto the ceramic compact; and infiltrating the alloy into the ceramic compact by heating up to a temperature at which the alloy melts.

Abstract: In a manufacturing method of a vane having an inner-ply vane within an outer-ply vane and a rear space in its inside, (a) an inner-ply vane woven-fiber formed body made of reinforcement fiber is formed on a jig corresponding to an inner surface profile of the inner-ply vane; (b) matrix is infiltrated into the inner-ply vane woven-fiber formed body to make the inner-ply vane; (c) the jig is removed; (d) a supplemental jig corresponding to the rear space and the inner-ply vane are integrated to form a integrated body; (e) an outer-ply vane woven-fiber formed body made of reinforcement fiber on a surface of the integrated body; (f) matrix is infiltrated into the outer-ply vane woven-fiber formed body to make the outer-ply vane. According to the manufacturing method, it becomes possible to manufacture a vane that can improve turbine efficiency by reducing thickness of a trailing edge of the vane.
