  • Patent number: 10005200
    Abstract: A system or apparatus and associated method is provided to remove pinholes from bio composite materials in order to increase the strength and functionality of the composites. The apparatus and method uses an inert gas, such as nitrogen, that is introduced into the processing chamber where the fiber and the polymer are combined to form the biocomposite material. The inert gas is introduced through an inlet into the chamber and creates a pressure differential between the interior and exterior of the product mixture to force the air and moisture out of the mixture and through an outlet or vent on the chamber, along with the inert gas and any other gases, thereby preventing or at least significantly limiting the formation of pinholes in the biocomposite product.

    Abstract: A method of manufacturing an object. A thermoplastic matrix material is melted to transform it into liquid matrix material. The liquid matrix material is fed into a chamber via one or more matrix inlets. A fiber is also fed into the chamber via a fiber inlet. The fiber in the chamber is contacted by the liquid matrix material. A coated fiber is extruded from an extrusion outlet of the chamber onto a substrate, the coated fiber comprising the fiber with a coating of the liquid matrix material, the substrate comprising a previously extruded coated fiber. The fiber moves in and out of the chamber at the same velocity relative to the chamber. The coating fuses with the previously extruded coated fiber and solidifies after it has fused with the previously extruded coated fiber. Relative movement is generated between the extrusion outlet and the substrate as the coated fiber is extruded from the extrusion outlet.

  • Patent number: 8663519
    Abstract: The present invention provides a method for the production of a fiber-reinforced plastics material profiled part. The method comprises the supplying of a tubular fiber braid in which a polymer matrix is arranged by being distributed therein. A longitudinal portion of the fiber braid is enclosed in a molding press. The molding press is heated to cure the polymer matrix in the longitudinal portion. After the press is opened, the fiber braid is drawn through the open press in order to position a further longitudinal portion of the fiber braid in the molding press. The further longitudinal portion is enclosed in the press. Another aspect of the invention is the provision of a device for the production of a fiber-reinforced plastics material profiled part.

  • Patent number: 8591781
    Abstract: In a method of producing a molded product, fiber such as carbon fiber is supplied to a robot delivery head where it is cut into shorter lengths and delivered to a molding tool in a desired orientation and in a desired number of layers to achieve a desired thickness and strength. Resin is then applied to the aligned fibers and cured to form the product. Alignment or substantial alignment of fiber is maintained by applying vacuum to the mold, by electrostatic means, or by coating the fiber with resin prior to application to the molding tool and heating the molding tool surface, or by coating or impregnating the fiber with a ferric powder and magnetizing the molding tool, or by applying a mist layer of epoxy in front of the shortened lengths of fibers. Fiber lengths and deposition rates are varied as required. The method facilitates fully automated production reducing process time and component costs. The invention also comprises a corresponding molded product.
