The gas turbine stator vane structure comprising a plurality of vanes 13, an outer platform 11 and an inner platform 12 is formed by integrally connecting a plurality of units 2 in a circle with fiber-reinforced prepreg tapes 10, 10′ each wound around and fused to an outside surface of the outer platform 11 and an inside surface of the inner platform 12. Each of the units 2 is constituted by (a) a core 3 composed of a laminate of fiber-reinforced prepregs and integrally having a web 31 for constituting a vane 13, and flanges 32, 33 integrally connected to both ends of the web 31 for constituting outer and inner platform pieces 21, 22; and (b) a skin layer 4 integrally molded around the core 3. The core 3 is at least partially exposed through windows of the skin layer 4 on both of an outside surface of the outer platform piece 21 and an inside surface of the inner platform piece 22, and fused to the fiber-reinforced prepreg tapes 10, 10′.
A unit for constituting a gas turbine stator vane structure comprising a plurality of vanes, an outer platform and an inner platform, said unit being constituted by (a) a core composed of a laminate of fiber-reinforced prepregs and integrally having a web for constituting a vane, and flanges integrally connected to both ends of said web for constituting outer and inner platform pieces;
The unit according to claim 3, wherein said flanges are formed by splitting both ends of a laminate of fiber-reinforced prepregs into two parts and bending the split ends in opposite directions in a T-shape manner, thereby providing said core with a substantially I-shape.
A gas turbine stator vane structure comprising a plurality of vanes, an outer platform and an inner platform, and formed by integrally connecting a plurality of units in a circle with fiber-reinforced prepreg tapes each wound around and fused to an outside surface of said outer platform and an inside surface of said inner platform, each of said units being constituted by (a) a core composed of a laminate of fiber-reinforced prepregs and integrally having a web for constituting a vane, and flanges integrally connected to both ends of said web for constituting outer and inner platform pieces;
A unit for constituting a gas turbine stator vane structure comprising a plurality of vanes, an outer platform and an inner platform, said unit being constituted by (a) a core composed of a laminate of fiber-reinforced prepregs and integrally having a web for constituting a vane, and flanges integrally connected to both ends of said web for constituting outer and inner platform pieces;
