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.

A method for producing a component by a 3D winding method, wherein the component has at least two arms, a bushing in each arm, and a torsion region connected to the at least two arms, comprising:
- laying down a filament or a plurality of parallel filaments comprising a fiber-reinforced plastic composite material on a core in a combination of a plurality of different winding patterns, wherein every filament is preimpregnated and wherein every winding pattern influences at least one mechanical characteristic of the component;
- selectively adjusting mechanical characteristics of the component by a repetition and a material selection of respective ones of the plurality of different winding patterns;
- and
- selectively adjusting mechanical characteristics of the component by a predetermined sequence and mixing of the plurality of different winding patterns,
- wherein two or more different winding patterns succeed one another to ensure a load transfer of a sub-portion of the component to another sub-portion of the component,
- anchoring the bushings at the core first by gluing the bushing to the core and then by guiding the filament in a winding pattern guided around each bushing as ring windings and cross windings,
- wherein the winding pattern guided around each bushing is different than the winding patterns of the at least two arms,
- wherein in a first winding pattern the filament is guided substantially parallel to a longitudinal axis of one of the arms,
- wherein in a second winding pattern the filament is guided substantially parallel to a longitudinal axis of a first one of the arms, substantially parallel to a longitudinal axis of a second one of the arms and in a web diagonal to a longitudinal axis of the torsion region.
