Abstract: A tooling fixture is disclosed for densification by chemical vapor infiltration of a fiber preform of a ceramic matrix composite. The tooling fixture includes a body having oppositely disposed first and second surfaces and a plurality of holes extending between the first and second surfaces, and a coating. The first surface is configured to be disposed adjacent to the fiber preform. The coating is disposed on the first surface and surfaces defining the plurality of holes. The coating comprises at least one of a ceramic material, hexagonal boron nitride, turbostratic boron nitride, and graphite.
