Abstract
A method for manufacturing a one-piece annular metal part having a reinforcing insert of composite material includes forming a blank of the part by superimposing, around a rotating cylindrical mandrel, layers of metal wire and layers of coated fiber, the layers of coated composite fiber being arranged in the blank according to the positioning of the insert in the part; placing the blank in a receiving tool, and applying a hot isostatic pressing treatment to the blank; and extracting the treated blank from the receiving tool and, as required, machining the treated blank to obtain the one-piece annular metal part having a reinforcing insert.
