PROBLEM TO BE SOLVED: To enable reinforcement fibers to be made continuous entirely in a turbine stator blade.SOLUTION: Stator blades arranged around a shaft and constituting a turbine nozzle each comprises: a blade portion extending in a radial direction of the shaft; an outer band portion continuous to an outer end of the blade portion and bent in the circumferential direction; a first hook portion continuous to a front end of the outer band portion in the axial direction and bent outward in the radial direction; a second hook portion continuous to a rear end of the outer band portion in the axial direction and bent outward in the radial direction; an inner band portion continuous to an inner end of the blade portion and bent in the circumferential direction of the shaft; a flange portion continuous to one end of the inner band portion in the axial direction and bent inward in the radial direction; and a reinforcement fiber fabric continuous to the entirety of the blade portion, the outer band portion, the first hook portion, the second hook portion, the inner band portion, and the flange portion and integrated with ceramics.SELECTED DRAWING: Figure 3 |
