Abstract

A method for processing a CMC airfoil includes nesting an airfoil fiber preform (10) in a cavity (20) of a fixture (12) that has first and second tool segments (16/18), closing the fixture (12) by rotating a first tool segment (16) about a hinge (22), the closing causing the tool segments (16) to clamp on a tail portion (14) of the fiber preform (10) and thereby conform the tail portion (14) to the fixture (12). While in the fixture (12), the fiber preform (10) is then partially densified with an interface coating material to form a partially densified fiber preform. While still in the fixture (12), one or more cooling holes are drilled into the trailing edge (10b) of the partially densified fiber preform. After the drilling, the partially densified fiber preform is removed from the fixture (12) and further densified with a ceramic matrix material to form a fully densified CMC airfoil.
