| 20080196825 | METHOD AND APPARATUS FOR MAKING STRUCTURES OF COMPOSITE MATERIAL, IN PARTICULAR AIRPLANE FUSELAGE SECTIONS - A method and a device for manufacturing hollow components out of a composite material, such as in particular sections of airplane fuselage, that include a skin and possibly strengthening elements. The method comprises inserting a multi-articulated arm fitted with a fiber placement head inside a female mold of elongated shape, said female mold being open via a longitudinal slit intended to receive the support means of said multi-articulated arm and a step of applying fibers to the inner molding surface of the female mold using the placement head to form said composite material skin, by displacement of the application head using the multi-articulated arm and relative displacement in translation of said support means of the multi-articulated arm along said longitudinal slit. | 08-21-2008 |
| 20080202691 | DEVICE FOR USING FIBERS WITH FLEXIBLE FIBER-ROUTING TUBES - A fiber application machine, for making components out of composite materials, that includes a system for displacing a fiber application head, fiber storage means, and fiber conveying means for conveying fibers from said storage means to the application head. The conveying means include flexible tubes connecting the storage means to the application head, each flexible tube being fitted with at least one longitudinal flexible blade of rectangular transverse cross-section, said flexible blade being placed substantially parallel to the plane of transport of the fiber received in the inner passage of the flexible tube. | 08-28-2008 |
| 20080216961 | APPLICATOR HEAD FOR FIBERS WITH SYSTEMS OF CUTTING AND LOCKING PARTICULAR FIBERS - A head for applying fibers in order to make components of composite materials, intended to be mounted at the end of a displacement system for applying to a surface a wide strip formed of a number of fibers. The head comprises an application roller, means for guiding fibers on said roller, cutting means including blades activated by activation systems for cutting the fibers upstream of the application roller, and blocking means including blocking studs activated by activation systems so as to block the fibers that have just been cut. The studs and the blades are activated by common activation systems which, for each fiber to be cut and blocked, displace a blade and a stud in order to cut and block the fiber. | 09-11-2008 |
| 20080216963 | APPLICATOR HEAD FOR FIBERS WITH PARTICULAR SYSTEMS FOR CUTTING FIBERS - The present invention relates to a head for applying fibers in order to make components of composite materials, intended to be mounted at the end of a displacement system for applying to a surface a wide strip formed of a number of fibers. The head comprises an application roller for applying fibers in the form of a strip, means for guiding fibers on said roller, and cutting means including blades activated by activation systems between a rest position and an active cutting position so as to cut the fibers upstream of the application roller. Said blades and associated activation systems are all placed on the side of the roller relative to said fibers. | 09-11-2008 |
| 20090229760 | Fiber application machine - A fiber application machine including a fiber application head with an application roller for the production of parts made of composite materials. The fiber application head further includes a guiding system to guide the fibers onto the application roller and/or means for the application of resin to each fiber as the fibers leave the guiding system. The fiber application machine can also include a fiber storing system and conveying means for conveying the fibers from the fiber storing system to the application head. The conveying means can comprise flexible tubes each tube being able to receive a fiber in its inner channel. The conveying means can further include a tension limiting system positioned between the application head and the storing system. The fiber application machine can further include a system for moving the application head. | 09-17-2009 |
| 20100252183 | METHOD AND MACHINE FOR APPLYING A BAND OF FIBERS ON CONVEX SURFACES AND/OR WITH EDGES - Embodiments of the invention relate to a fiber application method and a fiber application machine for producing parts in composite material, such as for the application of a band of fibers on convex surfaces and/or with edges. The machine comprises a fiber application head and a moving system for moving said application head. The application head comprises a compacting system including a compacting roller intended to come in contact against the application surface to apply the band, and a compacting member placed downstream from said compacting roller and exhibiting a substantially planar contact surface, said compacting member being capable of being pressed by its contact surface, against an application surface, substantially on the entire width of a band, by at least one contact line. | 10-07-2010 |
| 20110011537 | Fiber application machine comprising a flexible compacting roller with a thermal regulation system - A fiber application machine for the production of parts made of composite materials comprising a compacting roller for applying on an application surface a band formed of at least a resin pre-impregnated flat fiber, and a heating system able to emit a heat radiation towards the band. The compacting roller comprises a rigid central tube provided with radial holes, and a cylinder made of an elastically deformable, flexible material, assembled on the central tube, and having a fluid communication assembly that brings the radial holes into fluid communication with the external surface of the cylinder. The machine includes a thermal regulation system that injects a thermal regulation fluid in the central tube internal passage. | 01-20-2011 |
| 20110011538 | Fiber application machine with compacting roller transparent to the radiation of the heating system - A fiber application machine for the production of parts made of composite materials comprising a compacting roller for applying on an application surface a band of at least a resin pre-impregnated flat fiber, and a heating system able to emit a heat radiation towards the band. The compacting roller comprises a cylinder made of an elastically deformable flexible material and substantially transparent to said heat radiation. | 01-20-2011 |
