  • Device for manufacturing a casing made of a composite material and manufacturing method using such a device
    Patent number: 9399315
    Abstract: A device for manufacturing a fan casing of a turbomachine made of composite material, in which a mold includes a cylindrical body of lengthways axis and side flanges, and in which a counter-mold includes a cylindrical body and side counter-flanges. The counter-flanges are configured to be attached securely to the flanges, the body of the mold and the body of the counter-mold are concentric, the preform is configured to be positioned between the body of the mold and the body of the counter-mold, and the material of the body of the mold has an appreciably higher expansion coefficient than that of the body of the counter-mold.
    Type: Grant
    Filed: April 20, 2011
    Date of Patent: July 26, 2016
    Assignee: SNECMA
    Inventors: Romain Plante, Jean-Pierre Cauchois, Louis Bettega, Jean-Louis Robert Marcel Castanie

  • Process for producing precision hollow articles made of composite material
    Patent number: 6290889
    Abstract: A process for producing a hollow article made of a composite material of reinforcing fibers embedded in a matrix of hot-polymerized resin includes a step in which at least one core made of a silicone elastomer is draped with at least one layer of resin-impregnated reinforcing fibers. A resultant assembly is moulded to shape the internal and external surfaces of the hollow article by simultaneous inward and outward compression of at least one resin-impregnated fiber layer caused by movement of mould walls towards each other and by thermal expansion of at least one core.
