Patent number: 9238282Abstract: A method for manufacturing a metal part by producing a preform with a fibrous structure of metal fibers, 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 including a cavity for molding the part. The first tool element is elongate in a direction between two ends, and the fibrous structure is at least partially formed by winding at least one metal wire around the first tool element in the direction, from one end to the other. The method can be used, for example, for manufacturing reinforcement parts for a fan blade of a turbojet engine.Type: GrantFiled: February 24, 2012Date of Patent: January 19, 2016Assignee: SNECMAInventors: Thierry Godon, Bruno Jacques Gerard Dambrine, Alain Robert Yves Perroux

Patent number: 5733495Abstract: A blank consisting of a spirally wound fiber for use in the manufacture of a fiber reinforced article of composite material is made by winding the fiber onto a helical track on the surface of a frusto-conical spindle, covering the wound fiber with a thermoplastic binder which sets to form a frusto-conical shell encasing the fiber, removing the shell from the spindle and placing the shell with its base on a plate, and heating the shell starting from its base so as to soften it and cause it to progressively collapse onto the plate to form a disc comprising a spirally wound fiber. If necessary the collapse of the shell may be assisted by pressing on the shell in a direction towards the plate.Type: GrantFiled: September 25, 1996Date of Patent: March 31, 1998Assignee: Societe Nationale d'Etude et de Construction de Moteurs d'Aviation "SNECMA"Inventors: Jean-Claude Robert Berthelemy, Gerard Philippe Gauthier, Ludovic Edmond Camille Molliex, Alain Robert Yves Perroux
