Abstract

A method of repairing a ceramic vane includes providing a ceramic vane (49) that includes a platform (64) and an airfoil section (66) that extends from the platform. The platform includes a mounting surface (78) for supporting the ceramic vane and the airfoil section includes a damaged region (70). An over-wrap fiber ply (72) 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 (74). A build-up layer (76) 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.
