  • Patent number: 9656450
    Abstract: An apparatus for laminating substrates includes a laminating fixture having an open-topped recessed space formed by a pair of corresponding sidewalls for holding a target substrate therein. The recessed space is communicable with an air evacuation passage. A supporting structure is formed in the recessed space for supporting two opposite ends of a flexible substrate thereon, such that a bottom of the flexible substrate is spaced from a laminating surface of the target substrate by a predetermined distance. A soft plate is disposed over the open-topped laminating fixture to form an airtight chamber in the laminating fixture. When the airtight chamber is vacuumed using a vacuum pump via the evacuation passage, the soft plate is subjected to a suction pressure and downward deformed to press the flexible substrate downward, causing the flexible substrate to deflect to attach its bottom on the laminating surface of the target substrate.

  • Patent number: 9238337
    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.

    Abstract: Disclosed is a method for making a membrane for use as a vacuum bag, a natural rubber vacuum bag made using such methods, and methods for using such a natural rubber bag to form a composite article. One method can include providing a substantially non-porous working surface having a desired shape for forming a vacuum bag, spraying at least one layer of a natural rubber liquid over at least a portion of working surface, and solidifying the natural rubber liquid to form a membrane having a shape substantially corresponding to that of the working surface. The membrane formed being elastically deformable and substantially impermeable for functioning as a vacuum bag in Vacuum Assisted Resin Transfer Molding, debulking, compaction, or similar processes.

  • Publication number: 20140370255
    Abstract: This invention relates to a method of producing a coextrusion blown film is described. The method involves coextruding a blown film having 3 to 11 layers, including a first skin layer and a second skin layer, the first skin layer comprising nylon, and the second skin layer having a different melting temperature than the first skin layer. The film is then cooled before being passed through steam. The method can be used to produce a coextrusion blown film that has reduced curling.

  • Patent number: 8906275
    Abstract: A method of manufacturing a textured element may include (a) collecting a plurality of filaments upon a textured surface to form a non-woven textile and (b) separating the non-woven textile from the textured surface. Another method of manufacturing a textured element may include depositing a plurality of thermoplastic polymer filaments upon a first surface of a polymer layer to (a) form a non-woven textile and (b) bond the filaments to the polymer layer. A textured surface may then be separated from a second surface of the polymer layer, the second surface being opposite the first surface, and the second surface having a texture from the textured surface.

  • Patent number: 8875653
    Abstract: A solar cell extrusion printing system that uses a micro-extrusion printhead to print longer central gridlines and one or more pairs of shorter “side” gridlines such that end points of the gridline sets form step patterns on an octagonal (pseudo-square) substrate. The printhead includes a set of central nozzles that receive ink from a first valve by way of a first flow channel to print the longer central gridlines, and additional sets of side nozzles that receive ink from additional valves by way of additional flow channels to print the shorter “side” gridlines. The central nozzles have outlet orifices that offset in the process direction from side outlet orifices of the side nozzles. A start signal is simultaneously sent to the valves such that ink is substantially simultaneously extruded through both the central and side orifices, whereby the extruded ink produces gridline endpoints having the desired step pattern.

  • Patent number: 8858861
    Abstract: A method for forming an overmolded container by covering a hollow inner bottle made of resin with an injection of a molten resin which forms an outer. The method comprises steps of setting the inner bottle in a mold with a space therebetween for forming the outer and circulating a pressurized gas into and out of a hollow space of the inner bottle through an upper opening thereof. The pressurized gas is supplied through a first path which opens toward an inner wall of the inner bottle and discharged out of the inner bottle through a second path. The pressurized gas supplied into and discharged out of the inner bottle is adjusted in pressure while the molten resin is being injected to the mold.

  • Patent number: 8845941
    Abstract: The present invention provides apparatus and methods for growing fullerene nanotube forests, and forming nanotube films, threads and composite structures therefrom. In some embodiments, an interior-flow substrate includes a porous surface and one or more interior passages that provide reactant gas to an interior portion of a densely packed nanotube forest as it is growing. In some embodiments, a continuous-growth furnace is provided that includes an access port for removing nanotube forests without cooling the furnace substantially. In other embodiments, a nanotube film can be pulled from the nanotube forest without removing the forest from the furnace. A nanotube film loom is described. An apparatus for building layers of nanotube films on a continuous web is described.

  • Patent number: 8840828
    Abstract: An apparatus and a method of conforming a blank onto forming surface sections of a forming tool by drawing a first vacuum against an elastic forming medium for transmitting forming forces from the elastic forming medium to the blank. The elastic forming medium is evacuated with the first vacuum for allowing the elastic forming medium to stretch and conform the blank to the forming surface sections. The elastic forming medium includes at least one void. A second vacuum is applied to the void for achieving a stiffened section of the elastic forming medium corresponding with the location of the void and corresponding with, when the elastic forming medium after the completion lies against the forming tool having the blank in between, a forming surface section of the forming tool where the blank requires a forming force being larger than that of surrounding sections of the elastic forming medium.
