| 20100291339 | MECHANICAL COMPONENT COMPRISING AN INSERT MADE OF COMPOSITE - The invention relates to a method of manufacturing a mechanical component comprising at least one insert made of metal matrix composite, within which matrix ceramic fibers extend, the composite insert being obtained from a plurality of coated filaments each comprising a ceramic fiber coated with a metal sheath, the method involving manufacturing at least one insert with a step of winding a bonded lap or bundle of coated filaments about a component of revolution. According to the invention, at least some of the winding is done in a rectilinear direction. | 11-18-2010 |
| 20100323574 | 3D COMPOSITE FABRIC - A fabric includes a base pattern having at least twenty-eight weft fibers disposed in a staggered configuration and forming eight columns that comprise in alteration four weft fibers and three weft fibers, the weft fibers extending in seven layers. The fabric further includes at least twelve warp fibers disposed in at least four offset parallel planes, each of the planes containing at least three parallel warp fibers that follow paths that are distinct from one another. | 12-23-2010 |
| 20110099791 | METHOD FOR PRODUCING A METALLIC PART COMPRISING INNER REINFORCEMENTS CONSISTING OF CERAMIC FIBERS - A method for producing a metallic part including inner reinforcements of ceramic fibers, according to which: at least one recess for an insert is machined in a metallic body having an upper surface; at least one insert of ceramic fibers in a metallic matrix is arranged in the recess; the insert is covered with a cover; the gap around the insert is placed under a vacuum and hermetically sealed; the entire metallic body with the cover is treated by hot isostatic compaction; and the treated assembly is machined to produce the part. The insert is rectilinear, and the recess for the insert in the metallic body forms a rectilinear groove, the cover being dimensioned so as to be able to placed on the insert in the recess after having been shrunk by cooling and to establish a tight fit in the groove by dilation such as to close the space. | 05-05-2011 |
| 20110107579 | PROCESS FOR MANUFACTURING A METAL PART REINFORCED WITH CERAMIC FIBRES - The invention relates to a process for manufacturing a metal part reinforced with ceramic fibres, in which:

| 20110129639 | PROCESS FOR MANUFACTURING A STRUCTURAL PART MADE OF AN ORGANIC MATRIX COMPOSITE AND PART OBTAINED - A process for manufacturing a structural part made of an organic matrix composite including: production of a fibrous structure, forming a preform by braiding rovings of a fibrous material on a mandrel that includes a reinforcement in its axial extension, impregnation of the preform with an organic resin; and curing of this resin, the reinforcement, forming the cover, having a bore with an axis perpendicular to the axis for housing a connecting member. Barbs, some of which are projecting, are incorporated into the reinforcement over at least part of the surface of which lying on either side of the bore, the braiding being carried out around the barbs so that the rovings at least partly criss-cross around the barbs. | 06-02-2011 |
| 20110143089 | MECHANICAL COMPONENT COMPRISING AN INSERT MADE OF COMPOSITE - A method of manufacturing a mechanical component, and winding device to implementing the method. The component includes at least one insert of metal matrix composite, within which matrix ceramic fibers extend, the composite insert obtained from a plurality of coated filaments each including a ceramic fiber coated with a metal sheath. The method manufactures an insert preform by winding a bonded lap or bundle of coated filaments about a cylindrical component. At least some of the winding is performed in at least one rectilinear direction. The method further inserts the insert preform in a first container; performs hot isostatic compaction of the first container; and machines the first container to form a rectilinear insert. | 06-16-2011 |
