Abstract
A method of repairing a ceramic vane includes providing a ceramic vane that includes a platform and an airfoil section that extends from the platform. The platform includes a mounting surface for supporting the ceramic vane and the airfoil section includes a damaged region. An over-wrap fiber ply is wrapped around the airfoil section and covers the damaged region. The over-wrap fiber ply is then densified with a ceramic matrix material to form a ceramic matrix composite over-wrap repair layer. A build-up layer is applied to the at least one mounting surface. A desired stagger angle is provided to the ceramic vane by adjusting a thickness and contour of the at least one build-up layer.
