  • Patent number: 11400663
    Abstract: Systems and methods are described where a volume receiving a liquid matrix and fibers at an inlet where opposing sides of the volume converge to form a gap and a moving surface in contact with the liquid matrix and the fibers and moving with respect to the liquid matrix and the fibers through the gap such that shear force is transferred to the liquid matrix and the fibers pushing the liquid matrix and the fibers forward through the gap, creating currents in the liquid matrix and increasing pressure. The increased pressure within the volume forms a barrier to entrained gases within the liquid matrix such that the entrained gases are inhibited from passing through the gap along with the liquid matrix and the fibers.

  • Patent number: 11400620
    Abstract: Methods and apparatus for curing curved cylinder-like workpieces (e.g., in the shape of a half or full barrel) made of composite material, such as nacelle honeycomb core composite sandwich structures. These methods enable tailored curing of composite nacelle structures, to significantly reduce capital cost and fabrication cycle time. In lieu of an autoclave or oven, a pressurized ring-shaped cure volume is defined by a partitioned enclosure that mimics the cylinder-like shape of the composite nacelle structure with only limited clearance (e.g., a partitioned enclosure comprising inner and outer concentric cylinder-like walls). A tool (e.g., a mandrel) and at least one composite nacelle structure supported thereon are placed in the cure volume for curing. Integrally heated tooling, optionally in combination with other heating methods, such as infrared heaters, is utilized to provide the temperature profile necessary for cure.

    Abstract: A molding die is mainly constituted of a die surface shell layer (15) having a die surface (32) responsive to the shape of a composite item and a support (16) supporting the die surface shell layer (15). The die surface shell layer (15) is made of a material having air permeability, and a prepreg material (34) is placed on a die-shaped surface (32) thereof. Then, the prepreg material (34) is covered with a nonpermeable vacuum bag film (35), and a cavity portion (30) of the support (16) is evacuated. The die surface shell layer (15) has air permeability, whereby it follows that air present on the die-shaped surface (32) is also discharged into the cavity portion (30) through the die surface shell layer (15). Consequently, the prepreg material (34) is pressed against the die-shaped surface (32) by the atmospheric pressure outside the vacuum bag film (35), and strongly adheres.

  • Publication number: 20150072862
    Abstract: The present disclosure relates to a multilayer film capable of releasing an active ingredient, for example a pesticide. The film has a bottom or internal layer composed in part of a water-soluble polymer fraction containing the active ingredient, and a top or external layer. The bottom or internal layer may have a water-insoluble fraction in addition to the water-soluble polymer fraction. Relative proportions of the water-soluble polymer fraction and of the water-insoluble fraction provide a pre-determined time of release of the active ingredient when the multilayer film is exposed to humidity and/or moist conditions. The present disclosure also relates to methods of making the multilayer film and to uses of the film.

  • Patent number: 8936695
    Abstract: A composite layup is formed on a tool and placed on a contoured part. The tool is contoured to substantially match the contour of the part. A set of location data is generated which represents the location of the part in space relative to the tool. An automated manipulator uses the location data to move the tool into proximity to the part and place the contoured layup on the part.

  • Publication number: 20150004527
    Abstract: A process for producing an ion exchange precursor resin membrane involves co-extruding an ion exchange precursor resin with an incompatible polymer to form a multilayer film having a layer of the ion exchange precursor resin supported on a layer of the incompatible polymer. The layer of incompatible polymer is then removed from the layer of ion exchange precursor resin to provide the ion exchange precursor resin membrane. The ion exchange precursor resin membrane may be converted to an ion exchange resin membrane by hydrolysis, and subsequent acidification if desired. Ion exchange resin membranes and ion exchange precursor resin membranes having a uniform thickness of 25 microns or less may be formed by the process.
