Abstract
A method includes laying-up a fabric made of ceramic tows to form a fiber preform that has a repeating pattern of seal arc sections, densifying the fiber preform with a ceramic matrix material to form a densified ceramic matrix composite body, and then either before or after the densifying, cutting the fiber preform or the densified ceramic matrix composite body, respectively, along boundaries between the seal arc sections to separate the seal arc segments from each other.
