Abstract

An airfoil component includes a first segment that has a first piece of a mount and a first piece of an airfoil. The first segment is formed of a first ceramic-based material. A second segment includes a second piece of the mount and a second piece of the airfoil. The second segment is formed of a second ceramic-based material. The first and second segments are bonded together along a bond joint such that the first and second pieces of the mount are bonded to each other and the first and second pieces of the airfoil are bonded to each other.

Claims (6)

1. An airfoil component comprising:

a first segment including a first piece of a mount and a first piece of an airfoil, the first segment formed of a first ceramic-based material;

a second segment including a second piece of the mount and a second piece of the airfoil, the second segment formed of a second ceramic-based material, the first and second segments being bonded together along a bond joint such that the first and second pieces of the mount are bonded to each other and the first and second pieces of the airfoil are bonded to each other; and

a third segment including at least one of a third piece of the mount and a third piece of the airfoil, the third segment being bonded with at least one of the first segment and the second segment along another bond joint.

2. The airfoil component as recited in claim 1 , wherein the third segment includes a third piece of the mount and at least a piece of an endwall of the airfoil.

3. The airfoil component as recited in claim 1 , wherein the third segment includes at least a piece of a trailing edge of the airfoil.
