SHAPING EQUIPMENT AND FACILITY FOR GAS-PHASE CHEMICAL INFILTRATION OF FIBROUS PREFORMS

摘要

A conformation tooling (100) for the chemical vapor infiltration of a fibrous preform comprises a structural enclosure formed by supports (140, 170) each provided with a multiperforated zone (141; 171). The supports (140, 170) have on their inside a disbursed zone (143; 173) including the multiperforated zone. The conformation tooling (100) further comprises first and second shaping mold functional elements (120, 150) each respectively present in the disbursed area of the supports. Each conformation mold functional element comprises a first face (120a; 150a) having a determined shape corresponding to a part shape to be produced and a second face (120b; 150b) held opposite the inner face of a support. Each functional element has a plurality of perforations (121; 151) and has a number of perforations, a size of perforations or a geometry of perforations different from the number, size or geometry of the perforations present on the support vis-à-vis. -screw.
