Abstract: Use of a fiber composite material connecting portion to connect a tubular fiber composite material structure to a connecting device, wherein the connecting portion has at least one fiber deflecting element in its interior, wherein the course of the long fibers from the fiber composite material component follows the shape of a fiber deflecting portion of a fiber deflecting element, so that the fiber direction thereof is deflected at the fiber deflecting portion, and wherein the long fibers do not completely loop around the fiber deflecting elements with which they are associated respectively, wherein the fiber deflecting elements consist of fiber composite material, for a pressure tank.

Abstract: A method and a device for deorbiting artificial satellites from Earth orbit, the artificial satellite having multilayer insulation, at least partially detaches at least one layer of the multilayer insulation from the artificial satellite. Due to detachment of the layer, the underlying satellite structure is exposed to environmental influences. This exposure accelerates the self-disintegration of the artificial satellite, and thereby reduces the mass and increases the ballistic coefficient. Splaying out the layer augments its cross-sectional area and leads due to energy reduction to a premature re-entry into Earth's atmosphere. A number of layers can be arranged here so that regardless of a rotation of the satellite, at least one surface is always directed against the aerodynamic flow.

Abstract: Production method for a spoke star (5) with one or more continuous fibre bundles (111), during which a production device (100) is used for winding a fibre coil (3) and for deforming the fibre coil (3) into a spoke star (5), wherein the production device (100) comprises a plurality of deflection devices (2) at the rim side and a plurality of deflection devices (4) at the hub side, wherein the deflection devices (2) at the rim side and the deflection devices (4) at the hub side are arranged around an interior of the arrangement (10) of the deflection devices (2, 4), wherein in a first step a continuous fibre bundle (111) is wound around at least a portion of the rim-side deflection devices (2) as a fibre coil (3), and in a second step, after this winding, at least a portion of the hub-side deflection devices (4) are shifted in the direction of the interior of the arrangement (10), the fibre coil (5) being deformed into a star, so that between the hub-side deflection devices (4) and the rim-side deflection devic

Abstract: A closed ring fiber reinforced frame structure is produced by first preparing a prepreg. A section of the prepreg is formed into a flange preferably after impregnation by folding the flange section along a folding line. The folding line is formed by securing a deformable or drapable fiber ribbon material, for example by sewing or stitching to a carrier substrate which is preferably also a fiber material. The sewing seam or stitching line becomes the folding line. The ribbon material is so secured to the carrier substrate that the fiber orientation of the ribbon material is uniformly distributed all around a ring component that is formed of the ribbon material on the substrate. The impregnated ring component with its substrate is then cured after the folding of the flange to complete the ring frame structure.

Abstract: A load carrying structure having a selectively rigid or flexible characteristic includes a thermoplastic material (7) having a softening temperature above the operating temperature range of the load carrying structure, and a heating arrangement (8) provided to selectively heat the thermoplastic material to above its softening temperature. During normal operation, the thermoplastic material is in a rigid state and the overall load carrying structure is rigid to the prevailing loads. By activating the heating arrangement to heat the thermoplastic material to at least its softening temperature, the thermoplastic material and therewith the load carrying structure becomes flexible so that it may be deformed to a different configuration by applying a deforming load.

Abstract: The invention relates to a fibre bundle impregnating process, in which the fibre bundle is placed on a support and the support, together with the fibre bundle thereon, is moved past an impregnating device. In this process the fibre bundle is supported during the impregnation process and consequently a fibre-reinforced plastic is produced, fibre breaks being largely avoided during its production. One of the possible variants of the inventive concept comprises an impregnating wheel, which receives the fibre bundle and leads it past an impregnating device.
