Abstract: A tooling fixture suitable for use in infiltrating a fibrous preform with a flow of reactant gas includes an outer surface and an inner surface defining a thickness therebetween, and a plurality of holes extending through the thickness of the tooling fixture. The plurality of holes includes a first hole having cylindrical geometry with a first pair of dimensions comprising a first length and a first diameter, a second hole having cylindrical geometry with a second pair of dimensions comprising a second length and a second diameter, and a third hole having cylindrical geometry with a third pair of dimensions comprising a third length and a third diameter. At least one dimension of the first pair of dimensions is different from at least one dimension of the second pair of dimensions, and at least one dimension of the second pair of dimensions is different from at least one dimension of the third pair of dimensions.

Abstract: A tooling fixture suitable for use in infiltrating a fibrous preform with a reactant gas includes an outer surface and opposing inner surface defining a thickness therebetween, and a plurality of holes extending through the thickness. Each hole of the plurality of holes includes an inlet at the outer surface, the inlet configured to receive a flow of the reactant gas, an outlet at the inner surface, a transition point between the inlet and the outlet, and an angled segment extending from the transition point to the outlet. Each hole of the plurality of holes has a first diameter at the inlet and a second diameter at the outlet, and the second diameter is greater than the first diameter.

Abstract: A tooling fixture suitable for use in infiltrating a fibrous preform with a flow of reactant gas includes at least one wall. The at least one wall includes an outer surface and opposing inner surface defining a thickness therebetween, and a plurality of holes extending through the thickness. Each hole of the plurality of holes includes an inlet at the outer surface, an outlet at the inner surface, a transition point between the inlet and the outlet, and a first corner defined by the outer surface and the inlet. An angle of the first corner is less than 90 degrees, each hole of the plurality of holes has a first diameter at the inlet and a second diameter at the outlet, and the second diameter is less than the first diameter.
