  • Publication number: 20120126060
    Abstract: The method of fabricating an aircraft part comprises the steps of placing in a stack comprising a preform at least one layer of a material that presents permeability to a predetermined resin that is less than the permeability of a portion of the preform that is the closest to the layer; and placing a resin presence sensor on a side of the layer that is remote from the preform.

  • Publication number: 20110272852
    Abstract: A process for manufacturing a piece made of composite material with a hollow form and including a fiber preform (50) that is embedded in a matrix, includes placing the preform (50) in a first chamber (64) delimited by a mold (52) that is in contact with the surface of the piece to be produced outside of the hollow form and a counter-mold (54) that is in contact with the surface of the piece to be produced inside of the hollow form, and using a mold (52) that is made in at least two parts (52.1, 52.2) and elements (78) for controlling the spacing of the at least two parts (52.1, 52.2) that are contiguous using the expansion phenomenon during the polymerization phase.

  • Patent number: 8001998
    Abstract: A weaving loom including a mechanism drawing-in threads, for insertion of picks, and for formation of a weaving shed, so as to render possible formation of a continuous angle or corner by a thread during weaving. The loom preferably also includes a vertical offset system, so that it is possible to weave a three-dimensional surfacic structure, the threads of which are continuous between the faces and at the level of the edges. The loom can be configured particularly for manufacture of continuous tridedral corners that are used as reinforcements for composite structures.

  • Publication number: 20110180960
    Abstract: A process for manufacturing a piece made of composite material including a fiber preform that is embedded in a matrix, includes placing the preform in a first chamber that is delimited by a first semi-sealed wall, i.e., permeable to gas and impermeable to a product that is able to form the matrix, extracting the gases in a second chamber that is delimited by a second gas-tight wall and the first semi-sealed wall so as to obtain the diffusion of the product that is able to form the matrix in the preform, characterized in that it consists in using—as a first semi-sealed wall—at least one plate with a number of pipes of tapered shape that empty on either side of the at least one plate and at least one semi-sealed membrane that is superposed on the at least one plate.

  • Publication number: 20110143085
    Abstract: A fiber structure that can be embedded in a matrix for obtaining a piece made of composite material, includes a first fiber element having a first support surface, at least one L-shaped fiber element having a base that is flattened against the support surface of the first fiber element at a junction zone and a wing that is not flattened against the first fiber element, and another fiber element having one part flattened against the wing of the at least one L-shaped fiber element. The elements are assembled by tapping fibers from a second surface of the first fiber element so as to form loops, at least certain fibers being oblique relative to the second surface, in a plane that is perpendicular to the junction zone, wherein certain loops of the oblique fibers protrude to the outside of the outer surface of a wing of at least one L-shaped fiber element.

  • Publication number: 20100269948
    Abstract: A weaving method that makes it possible to directly produce three-dimensional structures having two-dimensional walls with corners, without requiring sewing or other joining between two edges. The weave is created by turning weft threads (24) into warp threads to create at least one face. The method is particularly suitable for weaving reinforcing pieces for composite structures such as three-dimensional corner reinforcements.

  • Publication number: 20090246531
    Abstract: A process for obtaining a core for the production of a stiffener (12) on a surface (14) of an element (10) that is to be made rigid, whereby the core is able to be placed between the element (10) to be made rigid and the stiffener (12) so as to obtain a cavity, includes steps of: Producing a central part (20) whose geometry is adapted to that of the cavity, whereby the central part (20) is made of a material that can dissolve or disintegrate; Inserting the central part (20) into an envelope (22) that is made of a thermo-retractable material; and Heating at least the envelope (22) so as to obtain its retraction around the central part (20).

  • Patent number: 6652261
    Abstract: An injection press for molding pieces of elastomer comprises a fixed platen, a moving platen, and a turret carrying a plurality of molds, the turret and the molds being interposed between the two platens so as to be capable of being clamped between them in order to close the molds, and the turret being mounted to rotate so as to move each mold sequentially between an injection station, vulcanization stations, and an unmolding station. The press also comprises an injector device adapted to inject elastomer into each mold while it is in the injection station, heater devices adapted to heat the molds, and a control device adapted to move the moving platen and to cause the turret to turn.

  • Patent number: 5378134
    Abstract: A press has a fixed lower platen, and an upper platen which is movable vertically by means of an actuator. A former corresponding to the article which is to be obtained is placed on the lower platen via a thermal insulation member, the former including channels for circulation of a heat exchange fluid. The material to be formed is placed on the former. The upper platen carries an assembly which has a resilient membrane, the periphery of which is sandwiched between a lower frame and a cover connected to a source of fluid under pressure, sealing between said membrane and the lid being ensured by the clamping pressure between these two parts which results partly from the force exerted on the moving platen and partly from the pressure of the fluid.

  • Patent number: 4766934
    Abstract: A closure head (2) for a hydraulic tube-testing bench includes a head body (4) including a first bore (5) into which one end of a tube (1) may be freely inserted. A second bore (11) of larger diameter than the first bore has a resilient sealing ring (10) inserted at the end thereof. A fluid under pressure is conveyed into a chamber (40) constituted between the outer periphery of the sealing ring and the second bore enabling the sealing ring to be contracted against the tube. The sealing ring is prevented from moving axially on its side furthest from the end of the tube by an annular series of thrust sectors (13) which are independent from said sealing ring. The sectors are clamped against the tube while also enabling them to be retracted away therefrom. The sectors are axially retained on their sides furthest from said sealing ring.
