摘要： A tooling assembly (10) suitable for use in infiltrating a fibrous preform comprises an outer tooling fixture (12) and an inner tooling fixture (14). The outer tooling fixture (12) comprises a first portion (20) removably attached to a second portion (20), and a first pair of oppositely disposed windows (28) defined by the first portion (20) and the second portion (20). Each of the first portion (20) and the second portion (20) comprises a base (22) with a recess. The inner tooling fixture (14) comprises a body defined by at least one portion (20), the body configured to at least partially surround the fibrous preform, a plurality of holes extending through a thickness of the at least one portion (20), each hole of the plurality of holes having a length (L) and a diameter (D), and a first neck region engageable with a recess of the first portion (20) or the second portion (20).
