Abstract: A tooling assembly suitable for use in chemical vapor infiltration (CVI) comprises a plurality of tooling fixtures arranged as a tower, with a central channel extending therethrough along a channel axis, and a lid atop the tower and covering the central channel. Each tooling fixture of the plurality of tooling fixtures comprises a plurality of walls defining an internal volume, and a plurality of holes through at least one wall of the plurality of walls, the plurality of holes placing the internal volume in flow communication with an external environment. Each tooling fixture of the plurality of tooling fixtures is in physical contact with an adjacent tooling fixture.

Abstract: A tooling assembly suitable for use in infiltrating a fibrous preform comprises an outer tooling fixture with a plurality of outer sidewalls defining an inner volume, each of the plurality of outer sidewalls having an outer wall thickness, and a window extending through the outer wall thickness of at least one outer sidewall of the plurality of sidewalls. The tooling assembly further comprises an inner tooling fixture positioned within the inner volume of the outer tooling fixture, the inner tooling having a plurality of inner sidewalls, each of the plurality of inner sidewalls having an inner wall thickness, and a plurality of holes extending through the inner wall thickness of at least one inner sidewall of the plurality of inner sidewalls. The at least one outer sidewall is positioned adjacent the at least one inner sidewall such that the window overlaps with at least a subset of the plurality of holes in the at least one inner sidewall.
