  • Patent number: 10011088
    Abstract: A semi-finished product arrangement for producing a fiber composite component by molding a planar semi-finished fiber composite product in a molding tool is provided. The arrangement includes the semi-finished fiber composite product and multiple holding elements fixed in place thereon and each extending beyond the edge of the semi-finished fiber composite product. The holding elements are countersunk in recesses of the semi-finished fiber composite product, in order to avoid a projection in terms of height.
    Type: Grant
    Filed: December 3, 2014
    Date of Patent: July 3, 2018
    Assignee: Premium Aerotec GmbH
    Inventors: Klaus Edelmann, Tanja Frese, Philip Hasemann, Juergen Krone, Helmut Krumpen, Andreas Leis, Angelos Miaris, Tim Neitzel, Arnoldt Quiring

  • Patent number: 7694544
    Abstract: A pressing device for forming steel sheet blanks into clips, which comprise curved planking elements and rectilinear stringer elements for connecting a fuselage cell skin to a stringer and to an annular rib in an aircraft fuselage, comprises at least one curved upper tool, at least one curved lower tool, at least one rectilinear upper tool, and at least one rectilinear lower tool. A steel sheet blank is receivable and formable between the at least one curved upper and lower tools and the at least one rectilinear upper and lower tools. The at least one curved upper and lower tool each comprises an upper and lower convexity surface designed to essentially correspond to each other in order to form the curved planking element in a single stroke surface model forming process by simultaneously bending and stamping.
