FRANZ-JUERGEN KUEMPERS has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9822469
    Abstract: In the production of a tubular fiber arrangement as an intermediate product for a composite part, the local conditions are taken into account in an especially simple and reliable manner with respect to the geometry of the composite part and its load profile. When forming the composite part on a core, the fiber mass supplied during the formation of the tube is proportional to the local circumference of the composite part which results from the diameter. The advancement speed of the core remains substantially constant.
    Type: Grant
    Filed: November 4, 2016
    Date of Patent: November 21, 2017
    Assignee: SGL Kuempers GmbH & Co. KG

  • Patent number: 8877661
    Abstract: Energy-absorbing textile structure, in particular for use in vehicle construction, which has high-tensile yarns for absorbing force, is formed by a braided fabric (2) with standing ends (3) in the force input direction and in that the textile structure has at least one region (4) with local modification of the fiber structure (2, 3).

  • Patent number: 8114793
    Abstract: Three-dimensional textile component structure made of high-tensile yarns, subject to loads in defined directions in use, comprises wound layers one above the other of yarn sheets (3, 4) made of the high-tensile yarns and at least one yarn sheet (2) extending along the structure, made of the high-tensile yarns with the yarns of each yarn sheet (2) fixed in position by a textile structure (5) made of intersecting yarn systems. Such textile component structures are made by a method wherein yarn sheets (2-4) are laid as layers at different angles one after the other around a preshaped core (1) to produce independent layers of parallel high-tensile yarns, with at least one yarn layer (2) being fixed by a textile structure (5) made of intersecting yarn systems, while the remaining yarn sheets (3, 4) are wound.
