<p>The invention relates to a process for manufacturing a metal part reinforced with ceramic fibres, in which: at least one housing (10A) for an insert is machined in a metal body (10) having an upper face (10B); at least one insert (11) formed from ceramic fibres in a metal matrix is placed in the housing; the insert is covered with a cover; a vacuum is created in the interstitial space around the insert and said space is hermetically sealed under vacuum; the assembly, namely the metal body with the cover, is treated by hot isostatic pressure; and said treated assembly is machined in order to obtain said part. The process is characterized in that the cover comprises an element (12) covering the insert (11) in the slot and projecting from the upper face, and a sheet (14) covering the upper face with said element (12). In particular, the insert (11) is straight and the housing for the insert in the metal body forms a straight slot.</p> |
