Abstract
A vane assembly includes a plurality of airfoils that extend from a first end to a second, opposed end. A first platform is at the first end and is joined to the plurality of airfoils. A second platform is at the second end and is joined to the plurality of airfoils. At least one of the first platform, the second platform and the plurality of airfoils include a three-dimensional arrangement of continuous fibers and at least one different one of the first platform, the second platform and the plurality of airfoils include a two-dimensional arrangement of continuous fibers.
Claims19
A vane assembly comprising:
- a plurality of airfoils extending from a first end to a second, opposed end;
- a first platform at the first end, the first platform being joined to the plurality of airfoils;
- a second platform at the second end, the second platform being joined to the plurality of airfoils, at least one of the first platform, the second platform and the plurality of airfoils including a three-dimensional arrangement of continuous fibers and at least one different one of the first platform, the second platform and the plurality of airfoils including a two-dimensional arrangement of continuous fibers.
A gas turbine engine comprising:
- a compressor section;
- a combustor in fluid communication with the compressor section;
- a turbine section in fluid communication with the combustor;
- a core flow path through the compressor section, the combustor and the turbine section;
- and
- a vane assembly located in the core flow path, the vane assembly including,
- a plurality of airfoils extending from a first end to a second, opposed end,
- a first platform at the first end, the first platform being joined to the plurality of airfoils, and
- a second platform at the second end, the second platform being joined to the plurality of airfoils, at least one of the first platform, the second platform and the plurality of airfoils including a three-dimensional arrangement of continuous fibers and at least one different one of the first platform, the second platform and the plurality of airfoils including a two-dimensional arrangement of continuous fibers.
A method of fabricating a vane assembly, the method comprising:
- forming a vane assembly with a plurality of airfoils extending from a first end to a second, opposed end, a first platform at the first end, the first platform being joined to the plurality of airfoils, a second platform at the second end, the second platform being joined to the plurality of airfoils, the forming including forming at least one of the first platform, the second platform and the plurality of airfoils with a three-dimensional arrangement of continuous fibers and at least one different one of the first platform, the second platform and the plurality of airfoils with a two-dimensional arrangement of continuous fibers.
