  • Patent number: 8303887
    Abstract: A tool for the infusion of a resin into a preform made of fiber material includes a mould which can be closed around the preform and in the body of which at least one inlet duct is formed to allow resin to be injected into the mould so that the resin can be infused into the preform. At least one reservoir which can contain the resin, is also formed in the body of the mould and is connected to the at least one inlet duct. The mould can be inserted in an autoclave and the reservoir is configured to permit the transfer of the resin from the reservoir to the inlet duct under the effect of the temperature and of the pressure that are produced in the autoclave, thus allowing the resin to be injected into the mould.

  • Patent number: 8287800
    Abstract: A method for making a polymeric web exhibiting a soft and silky tactile impression on at least one side thereof. The method comprises the steps of providing a forming structure being moveable upon a forming drum and comprising a plurality of protrusions extending from the forming structure, the protrusions being generally columnar forms having an average aspect ratio of at least about 1. The forming structure is disposed adjacent a vacuum chamber and vacuum is applied at a sufficient level to induce a sufficient partial pressure to conform a precursor web to the forming structure, thereby forming the polymeric web. The precursor web can be cast directly onto the forming structure, or it can be re-heated by re-heat means to elevate its temperature sufficiently to permit vacuum formation.

  • Publication number: 20120153546
    Abstract: A method of debulking a fiber preform includes debulking a three-dimensional fiber preform from a first size to a second, smaller size. A solvent may be infiltrated into the preform to distribute a tackifier material therein. The solvent is then removed and the dried preform is compressed to the smaller size such that, upon removal of the pressure, the tackifier material causes the preform to substantially remain at the smaller size.

  • Patent number: 8202469
    Abstract: There is provided a method of manufacturing a hollow structural member suitable for precisely manufacturing a hollow structural member whose pitch space of the hollows is below 30 ?m. The method of manufacturing a hollow structural member of this invention is to encapsulate, by using a gas-permeable material in part of a material that constitutes the substrate (5) for manufacturing the hollow structural member, a high-pressure gas by injection in advance, under high-pressure conditions, into the gas-permeable material; to form a plastic deformation film (10) on a surface under reduced-pressure conditions; and to expand and draw the plastic deformation film (10), while preventing the plastic deformation material from entering the recesses (5b), by discharging the high-pressure gas that is encapsulated in the gas-permeable material into each of the recesses (5b), whereby the hollow structural member is manufactured.

  • Patent number: 8178032
    Abstract: The present invention generally relates to a mold assembly (32, 34) and a method of using the mold for the manufacture of composite parts which, more particularly, are generated from a strengthener in a generally solid phase and a matrix in a generally liquid phase. Various types of molds and processes may be used in order to impregnate a strengthener with a matrix such that a composite part may be manufactured, but the efficiency rate and the duration of the manufacturing process significantly varies depending on the chosen type of mold and process. The present invention relates to a mold assembly and to the manufacture of composites by using the mold assembly which includes the injection of the matrix in the mold assembly containing the strengthener and a deformable member (36) which favors the impregnation of the matrix toward the strengthener.

  • Patent number: 8118959
    Abstract: A forming tool and method for its use with flat pre-preg composite laminate assemblies which incorporates a mandrel segmented into multiple forming blocks, the forming blocks sized to receive a draped composite laminate assembly with all portions of the composite laminate assembly spaced from a shaping surface on each block. A spline plate engages the shaping surface of the forming blocks to provide a neutral axis for maintaining the entire composite laminate assembly in tension during forming. In the exemplary embodiments, the draped composite laminate assembly is formed to the forming blocks from the flat composite laminate assembly and maintained in contact with the forming blocks using a vacuum bag. The mandrel forming blocks are then displaced to a desired curvature on the spline plate.
