Document Type and Number:
WIPO Patent Application WO/2012/114053
Kind Code:
A3
Abstract:
The present invention relates to a method for manufacturing a metal part by producing a preform with a fibrous structure consisting of metal fibres (36), and subjecting the preform to hot isostatic pressing in a tool until a solid part is obtained, the tool including at least one first element (51) having a cavity for moulding the part. The method is characterised in that the first tool element (51) is elongate in a direction XX between two ends, and the fibrous structure is at least partially formed by winding at least one metal wire (36) around said first tool element (51) in said direction, from one end to the other. The invention can be used for manufacturing reinforcement parts for a fan blade of a turbojet engine.
