Abstract: A method for producing a structural component part (1) from a fiber-reinforced plastic according to a three-dimensional winding process. Threadlike or strand-shaped fiber material (12) supplied on at least one bobbin (18) is wound around at least one filament carrier (11) in at least one winding pattern by at least one computer-controlled winding device (10). The fiber material (12) is laid down on the filament carrier (11) with a filament tensile force (FZN) that is preadjusted by a control device (14). The filament tensile force (FZist) is controlled depending on location and/or depending on path in order to take into account specific lay-down locations (29) on the filament carrier (11) in which a lay-down path (28) predefined by the winding pattern is departed from owing to the local geometry at preadjusted filament tensile force (FZN).

Abstract: The invention is directed to an apparatus (10) for manufacturing fiber-reinforced component parts (1) according to a three-dimensional winding method, comprising at least one computer-controlled winding machine for winding filiform continuous fiber strands (12) provided on at least one spool (18) around at least one fiber carrier (11) arranged on a pivot pin (16) with at least one winding pattern. The at least one winding machine is constructed as a robot arm (13) which has a plurality of rotational axes and which lays down at least two fiber strands (12) simultaneously. The at least one robot arm (13) is adapted to simultaneously lay down the at least two fiber strands (12) so as to be distributed to at least two fiber carriers (11) arranged, respectively, on a separate pivot pin (16) and/or to simultaneously lay down the at least two fiber strands (12) on only one fiber carrier (1) arranged on a separate pivot pin (16).

Abstract: A four-point link for a vehicle includes a core element and a main laminate comprising a fiber reinforced plastics composite material, which wraps around the core element. The core element comprises four load-introducing elements and a foam core, and the four load-introducing elements (4) are connected by positive engagement to the foam core (5). The four-point link has four additional windings, wherein a respective additional winding wraps around a first, second, third and fourth load-introducing element and operatively connects a respective one of the latter to the main laminate. Compressive forces can be introduced into the main laminate (3) by means of every additional winding (6).

Abstract: A component part for a motor vehicle having a hollow profile portion of a fiber-reinforced plastic and a load introduction element of a metal material. The hollow profile portion and the load introduction element are connected in a common connection portion via a nondetachable, glued plug-in connection in which an end portion of the load introduction element and an end portion of the hollow profile portion engage in one another by positive engagement. The end portion of the load introduction element has a spline with teeth extending in longitudinal direction of the common connection portion so that the stiffness of the end portion of the load introduction element reduced in longitudinal direction of the common connection portion.

Abstract: A method for producing a component by a 3D winding method, a filament or a plurality of parallel filaments having a fiber-reinforced plastic composite material is or are laid down on a core in a combination of a plurality of different winding patterns. Every filament is preimpregnated. Every winding pattern influences at least one mechanical characteristic of the component. The mechanical characteristics of the component are selectively adjusted by the sequence, repetition, mixing, and material selection of the individual winding patterns.

Abstract: A method for producing a structural component part (1, 33) from a fiber-reinforced plastic according to a three-dimensional winding process. A threadlike fiber material (12) is supplied on at least one bobbin (18) and constructed as a towpreg semifinished product is wound around at least one filament carrier (11) in a winding pattern by a computer-controlled winding device. The towpreg semifinished product is a mixture (30) of a thermoset resin, a hardener, an accelerator and plastic fibers (29) embedded in the mixture (30). The fiber material (12) is guided on the filament carrier (11) by a guide element (24) having a circular outlet cross section and arranged at a fiber guide device (25), the fiber material (12) deflected by the guide element (24) when the winding pattern is formed. The fiber material (12) is brought in contact with the guide element (24) during a deflection.
