  • Patent number: 10232573
    Abstract: A system for repairing a component made out of a plastic comprises a frame, a multiaxial guide device coupled with the frame, with a tool holder arranged thereon, an optical acquisition device, a processing device, and a plastic deposition device. The frame comprises a mounting device for retaining the frame on a component surface. The optical acquisition device, the processing device and the plastic deposition device are arranged on the tool holder. The optical acquisition device is set up to optically inspect a surface area of the component lying in proximity to the frame from at least one viewing angle, so as to acquire the spatial structure of the surface area. The processing device is set up to remove material of a damaged area from the component for generating a base surface with a desired structure and boundary edges.

  • Patent number: 9399325
    Abstract: A device for automatically laying and draping a plurality of web-form portions of a dry sheet-like formation, in particular of a multiaxial laid fiber fabric and/or a woven reinforcing fabric to create a profiled preform on a core by repeated laying and draping of the portions in order to produce a reinforcing profile with a composite material. Accordingly at least one portion, is kept in at least one cassette between two roller conveyors ready for laying on the core. As a result of the preferably simultaneous laying of preferably more than one prefabricated portion of the sheet-like formation on the core by means of at least one cassette of the cassette arrangement a profiled preform can be fully automatically laid and draped quickly and with great dimensional accuracy and at the same time with good reproducibility for the production of CRP profiles.

  • Patent number: 9079366
    Abstract: The invention relates to a production method for producing seamless, integral aircraft fuselage sections. The method comprises the following steps: a) application of a first vacuum film to a stable winding core and evacuation of the first vacuum film, b) depositing of the fuselage section in layers on the winding core by wrapping the same, c) application of an outer mold that is unstable compared to the stable winding core, to the fuselage section, wherein the winding core stabilizes the outer mold, d) application of a second vacuum film to the outer mold, e) aeration of the first vacuum film and evacuation of the second vacuum film in order to draw the fuselage section closer to the outer mold and detach it from the winding core at least in one region, a) curing of the entire arrangement in an autoclave to produce the finished fuselage section.

  • Patent number: 8845946
    Abstract: A method for manufacturing a fiber composite component having an integral structural design includes positioning a sheet-like fibrous semi-finished product in a mold that defines an outer contour of the fiber composite component. Dimensionally stable fibrous semi-finished products, each having dimensions corresponding to a respective portion of the manufactured fiber composite component, are arranged on the sheet-like fibrous semi-finished product. The dimensionally stable fibrous semi-finished products are stabilized and fixed in place using mold cores. The semi-finished products are resin infiltrated using one of a first or a second gating process so as to form a construct. The first gating process includes gating via the mold cores at a head of each dimensionally stable fibrous semi-finished product and performing extraction in an area of the mold.
