Abstract
Official abstract text for this publication.
A method of forming a component for use in a gas turbine engine includes the steps of forming an airfoil/root assembly; creating a platform assembly structure having an opening; inserting the airfoil/root assembly into the opening; and bonding the platform assembly structure to the airfoil/root assembly to form the component.
First claim
Opening claim text (preview).
What is claimed is: 1. A component for use in a gas turbine engine comprising an airfoil and a root portion formed from a ceramic matrix composite and a platform assembly comprising a ceramic matrix composite three dimensional woven material bonded to said airfoil and root portion; wherein said airfoil and root portion is formed from a plurality of layers of a uni-directional tape material; wherein said platform assembly includes integral chord-wise buttress structures located spaced apart in the chord-wise direction along the length of said platform assembly structure; and an interfacial layer between the airfoil/root portion and the platform assembly structure. 2. The component of claim 1 , wherein said platform assembly overlays the root portion so that contact between the blade and a disk occurs on an exterior surface of the platform assembly. 3. The component of claim 1 , wherein said component is turbine blade.
