Abstract
A method for densifying a fibrous texture made of ceramic material with a ceramic matrix used in injection equipment including a mold cavity defined between a mold and a counter-mold, the mold cavity defining an internal space, and a membrane comprising a stiffened zone, the membrane being intended to be placed between a fibrous texture present in the mold cavity and the counter-mold, and the stiffened zone of the membrane having a Young's modulus greater than 200 GPa, the method including placing a predensified fibrous texture in the mold cavity, the predensified fibrous texture having corrugations on the surface and placing the membrane on the predensified fibrous texture in such a way that the stiffened zone of the membrane is in contact with the peaks of the corrugations of the predensified fibrous texture; closing the injection equipment, and densifying.
