Patent ID: 8418343

Claim:
A process for manufacturing a metal part having internal reinforcements formed from ceramic fibers, comprising: at least one housing for an insert is machined in a metal body having an upper face; at least one insert formed from metal-coated ceramic fibers is placed in the housing; the insert is covered with a cover; a vacuum is created in an interstitial space around the insert and the space is hermetically sealed; an assembly of the metal body with the cover is treated by hot isostatic pressure; and the treated assembly is machined to obtain the part, wherein the insert is straight, and the housing for the insert in the metal body forms a corresponding straight slot, and the cover is cooled before being placed in the housing, the cover being configured to allow it to be fitted onto the insert with a clearance in the housing after having been contracted by being cooled and to exert a tight fit by expansion in the slot so as to close off the space.
