Abstract: A device for producing textile planar structures formed of a plurality of portions deposited beside one another of fiber rovings. A supply device provides a fiber rovings at a transfer installation. A plurality of path guiding rails are disposed beside one another and above the depositing face. A gripper unit and a cutting unit are disposed on each path guiding rail. Each gripper unit and each cutting unit is movable and positionable along the path guiding rail independently of the gripper units and cutting units of the other path guiding rails. The gripper units grab the fiber roving from the transfer installation and move their free end to a desired terminal position. The cutting units severs the rovings at a cutting position. The gripper units and the cutting units have a downholder for pressing the fiber roving against the depositing face.

Abstract: A method for producing a load introducing element for a control surface of an aircraft or a spacecraft, includes cutting to size preformed fibrous substructures out of a fibrous material. The method also includes draping the fibrous substructures to mold at least one first component, at least one second component and at least one first flange in the form of a single semi-finished product. Further, the method includes inserting the semi-finished product into a mold, injecting matrix material, and curing the semi-finished product to form a finished product.

Abstract: The invention relates to a method for depositing one- or two-dimensional fiber structures in order to form a two- or three-dimensional fiber structure, in particular a fiber structure in the form of a fiber-reinforced plastic (FRP) or FRP semi-finished product, using a production machine including at least one depositing device and at least one fiber support. The one- or two-dimensional fiber structures have at least one unidirectional fiber layer. The depositing device deposits the one- or two-dimensional fiber structures onto the fiber support in a depositing direction in a controlled manner such that the fiber directions of the deposited one- or two-dimensional fiber structures assume an angle ?>20°, preferably ?>60°, and a maximum of ?=90°, relative to the depositing direction. The one- or two-dimensional fiber structures are deposited on the fiber support in a substantially tension-free manner with respect to the fiber direction of the fiber structures.

Abstract: In a device and method for manufacturing preforms of fiber reinforced plastic, in a first step, continuously supplied fiber layers are laterally reshaped in a predetermined manner, and the section that is obtained is curved longitudinally in a specific manner in a second step.

Abstract: A device for producing fiber preforms including a plurality of unwind stations, a plurality of grippers and at least one first molding tool. Further, a method includes the successive steps of tensioning threads or rovings for a first layer with grippers, draping the first layer over a first molding tool, severing of the threads or rovings of the first layer, tensioning threads or rovings for a second layer with grippers, draping an additional layer over the first forming tool, and severing the threads or rovings of the second layer.

Abstract: A device for producing fiber preforms includes a plurality of unwind stations, a plurality of grippers and at least one first molding tool. Each gripper is movable on a path between a maximum position and a pick-up position. The pick-up position is provided at a thread transfer point and is closer to the unwind station than the maximum position. The first molding tool has a draping position in the region of the connecting lines between the maximum position and the thread transfer points, and a starting position outside the connecting lines. A thread tension control for the threads or rovings is provided.

Abstract: A method and a device for producing fiber preforms which are, for example, a precursor in the production of fiber reinforced plastic components, are disclosed. The method includes the steps of tensioning the threads or rovings, draping the threads or rovings over a molding tool and attaching the threads or rovings to a fiber preform. A plurality of separate grips grip individual or a plurality of threads or rovings at a plurality of thread transfer points allocated respectively to the individual grippers. The grippers are then moved in substantially parallel paths relative to each other and the threads or rovings are thereby tensioned side by side.

Abstract: A device and corresponding method for producing three-dimensional components from impregnated fiber tapes. The device includes a plurality of grippers, arranged alongside one another, for gripping fiber tapes impregnated with matrix material, the grippers can be displaced in a linear manner on mutually parallel paths between a pick-up position and a maximum position such that the fiber tapes can be tensioned between the grippers and respectively associated transfer devices; a rotatable table on which the fiber tapes can be laid in a first and at least one additional layer; a severing device which can sever the fiber tapes close to the transfer device; a heating device for heating the layers to 160° C. to 400° C.; a first molding tool and one or more additional molding tools which can be moved together to three-dimensionally form the layers; and a transporting device which can transport the heated layers between the molding tools.

Abstract: A load introducing element for a control surface of an aircraft or a spacecraft comprises at least one first component, one second component and one first flange. At least one surface area of the first component is adapted to conform to the inner contour of the control surface. The second component has at least one eye for receiving bearing means for mounting the control surface. A cross sectional profile of the first component has two or more essentially straight legs, which are connected together on their upper side by an upper edge which is adapted to an upper contour of the control surface. The load introducing element is formed by a fiber reinforced composite material having an integral type of construction in which all of the components are jointly infiltrated and cured. The invention also provides a method for producing such a load introducing element, a drive armature and an aircraft that includes such a load bearing element.
