  • Publication number: 20190202144
    Abstract: A methods for producing a fibrous preform includes placing a fibrous mat onto a depositing surface, the depositing surface being formed by a web face of a mould core, a first support surface of a first support installation and a second support surface of a second support installation. The fibrous mat is covered by a film and is pressed in a planar manner onto the depositing surface by generating a vacuum. Bringing to bear the fibrous mat on lateral faces of the mould core that extend transversely to the web face is subsequently performed by moving the support installations and the mould core relative to one another in such a manner that a level differential between the web face of the mould core and the support surfaces of the support installations is enlarged. A device for producing a fibrous preform is furthermore described.

  • Publication number: 20190153642
    Abstract: A semi-finished textile for producing a fiber composite component part has a textile structure and a fixation structure so as to provide a semi-finished textile that can be easily handled and that is suitable for use in complex component part shapes. The textile structure includes a first multitude of reinforcement-fiber bundles of high-performance fibers. Displacement sections are formed between adjacent reinforcement-fiber bundles and adjacent reinforcement-fiber bundles can be displaced against each other. The fixation structure fixates the reinforcement-fiber bundles, depending on the textile structure, with a fixation pattern in such a way that the reinforcement-fiber bundles are fixated at least partially and the displacement sections remain at least partially free.

  • Publication number: 20190107480
    Abstract: An adhesive film and arrangement and method for verifying an adhesive attachment. A mechanical strength of adhesive film structure is matched to a target binding force of a bond produced using the film where when the film is pulled from the substrate or a material layer with peeling stress on the bond for verification of adhesive attachment, the film fails with exceedance of the mechanical strength of the structure when the strength of the bond attains or exceeds the target binding force, and the adhesive film when pulled apart does not fail when bond strength does not attain target binding force. An arrangement is disclosed for verification of adhesive attachment, having a substrate, a component bonded to the substrate by an adhesive film, and at least one test section. The test section is formed by projection of the film across an edge of the component bonded to the substrate, the projection being bonded to regions of the substrate.

  • Publication number: 20190030841
    Abstract: A device for producing a curved fiber preform from a bi- or multidirectional fiber semi-finished product, in particular for an aircraft or spacecraft fuselage component has first lamellae and second lamellae formed to be couplable to one another criss-cross such that they are positioned on a shared plane and thus form a grid. The lamellae at least in part are formed resiliently bendable about an axis intersecting the shared plane such that a local orientation of the lamellae in the grid changes. An adhesion device or structure is formed for temporarily adhering the fiber semi-finished product and is configured such that the local fiber orientation of the fiber semi-finished product also changes accordingly when the lamellae bend.

  • Patent number: 9987770
    Abstract: A device for shaping a workpiece is provided. The device includes at least one first and one second component between which the workpiece to be shaped can be molded under the effect of heat. The design and/or the material properties of the first and/or the second component are selected such that the component's thermal expansion is different in different directions.

  • Patent number: 9475266
    Abstract: A method for stabilizing a honeycomb core for a sandwich-type structural component includes configuring the honeycomb core. A hardenable adhesive layer is applied to at least one exterior surface of the honeycomb core. A semi-permeable membrane is positioned on the at least one exterior surface. The membrane is gas-permeable and liquid-impermeable. Air in the honeycomb core is drawn off through the semi-permeable membrane. The adhesive layer is hardened.

  • Patent number: 8702884
    Abstract: A method for preforming a textile semi-finished product, including arranging a textile having at least two layers of fibers, interwoven fibers and/or fiber bundles that are at least in part arranged on top of each other. The method also includes; fixing-in-position of the fibers of the textile against each other and then cutting-to-size of the textile. The fixing-in-position of the textile involves irradiating via a laser beam in order for the melt-on binder of the textile to be melted on only in a localized fashion and not evaporated. The fixing-in-position occurs along a fix-in-position line, the cutting-to-size occurs along a cut-to-size line, and the fix-in-position line is located at a distance relative to the cut-to-size line that is so small that any fraying of the textile is reduced or suppressed altogether.

  • Patent number: 8573035
    Abstract: The invention relates to a method for measuring and/or testing a geometric design parameter, particularly waviness, of a planar textile (10), comprising the steps: disposing the planar textile (10) in an intermediate space (26) between a support (20) and a flexible film (22), applying a differential pressure (?p) between the intermediate space (26) and the environment, so that the film (22) adapts to the planar textile (10), and capturing a surface profile (32) of the film (22).

  • Patent number: 7959104
    Abstract: The invention relates to a flying device which can efficiently move in the air by aerodynamic forces and by direct force transmission on the ground, without the need for independent drive and thrust generation systems for the two modes of movement. The rotors (1) of the flying device are provided on the outside thereof with an annular rotating covering (4), connected directly to the rotor blade tips, which, when the flying device is on the ground and the rotor rotational axes (2) are correspondingly pitched about an axis (3), come into contact with the ground. The covering (4) hence permits a movement of the flying device on the ground by rolling, which is based on a direct force transfer to the ground. A further rotor pitching axis (5) permits the flying device to be controlled in the air and on the ground by means of the same actuator system.
