Abstract
A process for manufacturing a one-piece axisymmetric part includes: superposition, around a rotating cylindrical mandrel of at least respectively inner and outer metal-coated composite fibrous structures, wound in first and second crossed directions on the mandrel; arranging, between the crossed inner and outer fibrous structures, at least one layer of metallic wire; then placing a blank of the part, formed by the fibrous structures and the layer of metallic wire, in a tool to apply to the blank a hot isostatic pressing treatment, and to obtain the part.

A method for manufacturing an integral rotationally symmetrical part by superposition, around a rotary cylindrical mandrel, of at least two metal-coated composite fibrous structures, respectively inner and outer, wound in first and second directions crossed on the mandrel, the method comprising:
- arranging, around the inner fibrous structure constructed on the mandrel in a first winding direction, at least one layer of metal wire;
- winding, on the layer of metal wire, the outer fibrous structure in a second winding direction;
- placing a preform of the part, formed by the fibrous structures and the layer of metal wire, in a receiving outfit to apply to the preform a hot isostatic compaction or isothermal forging treatment;
- and
- extracting a treated preform from the outfit, and if appropriate, machining the treated preform to obtain the part.
