METHOD TO TIE COMPOSITE VANE PLATFORM AND AIRFOIL DESIGN DETAILS

Abstract: a method of forming a ceramic matrix composite (cmc) vane including an inner diameter platform, an outer diameter platform, and an airfoil extending between the inner diameter platform and the outer diameter platform includes laying up a ceramic preform by arranging at least one core formed from a first ceramic material, and laying up, over the at least one ceramic core, a plurality of contoured plies, each of the plurality of contoured plies formed from a second ceramic material. each of the plurality of contoured plies partially forms the inner diameter platform, the outer diameter platform, and the airfoil of the vane. the method further includes densifying the ceramic preform with a matrix.
