Abstract
A method of fabricating an airfoil includes providing an airfoil core tube that is made of a rigidized ceramic fabric, using the airfoil core tube as a mandrel by braiding a plurality of ceramic fiber tows around the airfoil core tube to form one or more braided layers, where the airfoil core tube and the one or more braided layers forming an airfoil preform, and densifying the airfoil preform with a ceramic matrix material to thereby form a ceramic matrix composite airfoil.
