Abstract (en)
[origin: WO2012117213A1] The invention relates to a method for manufacturing an integral rotationally symmetrical part, which includes producing a blank of the part around a cylindrical mandrel, the blank including at least one fibrous structure made of composite ceramic fibres coated with metal, followed by the diffusion-welding treatment of the blank by hot isostatic pressing, and optionally machining the thus-treated blank in order to obtain the part. According to the invention, the method is characterised in that the blank includes at least a first metal-wire layer (6) between the mandrel (10) and said composite fibrous structure (7), and at least a second metal-wire layer (8) arranged around said composite fibrous structure so as to cover the latter.
