  • Patent number: 8715450
    Abstract: The present invention provides a foamed member capable of inhibiting or preventing foam breakage at the time when the foam member is peeled from a carrier tape, even when the foamed member has a high expansion ratio. The foamed member has a thermoplastic resin foam layer containing a thermoplastic resin foam formed through a step of impregnating a high-pressure inert gas into a thermoplastic resin and subsequently reducing pressure, and at least one of a thermoplastic polyester-based resin layer and a thermoplastic elastomer resin layer disposed on at least one side of the thermoplastic resin foam layer.

  • Patent number: 8715560
    Abstract: The present invention provides a method for controlling the thickness of composite laminates cured on closed angle tools. The invention utilizes a peel ply rather than a breather during the preparation for cure of laminate parts having a substantially uniform initial thickness. This method allows composite parts to be formed with greater uniformity and without the need for extra hardware. The composite part formed by the above method may find use in a wide variety of applications, including, for example, automotive and aerospace applications. Thus, for example, a composite part formed in accordance with the present invention is ideally suited for use as a shear tie in a commercial aircraft, which are used to secure the inner framework of the aircraft to the airplane skin.

  • Patent number: 8715561
    Abstract: A method of assembling and shaping a laminate panel. An intermediate member is mounted on a lay-up table and a lay-up is assembling by laying a series of plies onto the intermediate member on the lay-up table. The intermediate member and the lay-up are then removed from the lay-up table and placed them on a shaped surface. The lay-up is then forced against the shaped surface, via the intermediate member, in a manner that modifies the shape of the lay-up to form a shaped laminate panel. Finally the shaped laminate panel is removed from the intermediate member. The lay-up table can thus support the flexible intermediate member during assembly, and can be relatively flat to enable the lay-up to assembled by an automated process.

  • Patent number: 8708014
    Abstract: A method for producing a composite structure comprising fiber reinforced material by means of vacuum assisted resin transfer molding is described. The fiber material is impregnated with liquid resin, and the method comprising the steps of: a) providing a forming structure comprising a rigid mold part and a second mold part, b) placing the fiber material in the rigid mold part, c) sealing the second mold part against the rigid mold part to form a mold cavity, d) connecting a source of uncured fluid resin to at least one resin inlet communicating with the mold cavity, e) connecting at least one vacuum outlet communicating with the mold cavity, f) evacuating the interior of the forming structure through the at least one vacuum outlet, g) supplying uncured resin from the source of uncured resin to the mold cavity through the at least one resin inlet so as to fill the mold cavity with resin, and h) curing the resin in order to form the composite structure.

  • Patent number: 8695203
    Abstract: Process for manufacturing a plastic fuel tank (FT) equipped with an internal accessory, by molding a parison using a mold comprising two cavities and a core, said process comprising the following steps: the parison is introduced into the mold cavities; the core is introduced inside the parison, the core having first been fitted with the accessory; the mold is closed so that the cavities come into leaktight contact with the core; the parison is pressed against the cavities by blowing through the core and/or applying a vacuum behind the cavities; the accessory is fastened to the parison by snap riveting using a device attached to the core; the mold is opened to withdraw the core; and the final molding of the parison is carried out by blow molding and/or thermoforming.

  • Patent number: 8650745
    Abstract: A thermal processing and consolidation system is provided that includes an upper chamber assembly lower chamber assembly, layup and demolding station, transfer assembly, automatic or permanent coupling system, and controller. The upper and lower chamber assemblies are coupled to form an enclosed plenum operable to maintain a pressurized environment about a tool. The layup and demolding station receives the tool and facilitates the layup, bagging and sealing of unprocessed components at the tool. A transfer assembly accurately positions the tool on the lower chamber assembly in alignment with the upper chamber assembly. An automatic or permanent coupling system provides services to the tool and the enclosed plenum. A controller directs services to be supplied to the enclosed plenum and tool in accordance with a set of process parameters. This set of process parameters allows an individual set of unprocessed components to be thermally processed and consolidated.

  • Patent number: 8646454
    Abstract: Oral appliances, methods of making oral appliances, and bite registration devices for use in making oral appliances are provided. An oral appliance includes a lower segment, and upper segments. The upper segments are operably connected to the lower segment using threaded elements. Rotational manipulation of the threaded elements causes the upper segments to be displaced horizontally relative to the lower segment about the lengths of the threaded elements, and the lengths of the threaded elements are substantially parallel to each other. A bite registration device for use in making an oral appliance includes a top surface including a protrusion and a bottom surface including a receptacle configured to receive the protrusion. The device is configured to be maintained in stacked relation to a like configured second bite registration device by mating the protrusion of the bite registration device with a receptacle of the second bite registration device.
