Abstract
A method for forming a CMC article includes wrapping first ceramic fibers around a mandrel to form inner fabric layers on the mandrel, depositing a first interface coating material on the first ceramic fibers, densifying the inner fabric layers to a partially-densified state with first ceramic matrix material, wrapping second ceramic fibers around the inner fabric layers to form outer fabric layers around the mandrel, depositing a second interface coating material on the second ceramic fibers, and densifying both the inner fabric layers and the outer fabric layers to a final-densified state with second ceramic matrix material.
