- a geometric shape of a core component for a fiber-reinforced braiding component for a vehicle can be defined.
- the manufactured fiber-reinforced right component can be used in any type of vehicle, such as a passenger car, a truck, but of course in other vehicles such as an airplane, a ship or a bicycle.
- the fiber reinforced braid member is formed as a hollow member produced by braiding the core member with a fibrous material comprising fibrous material comprising one or more types of fibers and a matrix material.
- the finished braiding component can furthermore, in particular depending on the requirements of the braiding component, the core component remain or else be removed.
- a core component with a geometric shape can be provided such that a required component geometry of the fiber-reinforced right component is reliably achieved.
- component properties of the fiber-reinforced braiding component can also be ensured, for example a preferred, for example constant, or at least substantially constant, fiber volume content.
- the inventive method can be carried out in particular by a computer unit, wherein such a computing unit can comprise a single computer, but of course also several, in particular also networked, computer.
- a virtual braiding component body is provided by the computer unit. Provisioning in the sense of the invention can in particular comprise a modeling of such a virtual braiding component body in a simulation program of the computer unit.
- the geometric shape of the braided component body is created in the computer unit such that it corresponds to the geometric shape of the right component or at least substantially corresponds.
- the braiding component body which is provided virtually in the computer unit corresponds at least in its geometric configuration to the braiding component to be produced.
- a geometric shape in the sense of the invention may particularly preferably comprise the outer surface of the braiding component.
- a braiding of the braided component body in the computer unit or by the computer unit is simulated.
- At least one braiding layer made of a fibrous material is reproduced on the outside of a surface of the right structural element body in this simulation.
- this layer of braid can be reproduced, for example, approximated by a rod model.
- the simulated braiding layer may in particular comprise a plurality of fiber types, for example glass fibers and / or carbon fibers, and / or simulate one or more matrix materials.
- the braiding of the right component body to Ben on a surface of the legal component body is to be understood in the sense of the invention such that the volume of the entire object simulated in the pitcher unit is increased by this braiding.

- the size of the grid cells is chosen such that they are as small as possible in order to provide the best possible, local resolution of the braiding in terms of the grid cells.
- the grid cells are not too small, otherwise the number of grid cells can be very large and this unnecessarily increases the computing time required to perform a method according to the invention.
- a wall thickness of the at least one legal position is determined by the computer unit for each of the screen cells divided in step c). This is particularly advantageous in that even in a simulated braiding, as is done in step b) of a method according to the invention, this wall thickness can be variable. This is in particular due, for example, to a changing geometry of the braided braided component body, since this may, for example, change the relative spacings of the individual fibers in the fiber material. Since the wall thickness is composed of the fibers of the fiber material and the matrix material, in particular, the wall thickness is variable with respect to a fiber density or the amount of added matrix material.

- a fiber-reinforced braiding component with particularly predictable and desired properties can thus be provided by a core component whose geometric shape has been determined according to a method according to the invention.
- a fiber volume content in particular a given fiber volume content, preferably a constant or at least substantially constant fiber volume content, of the fiber-reinforced right component is taken into account in step e).
- a fiber volume content is in particular a content of fibers of the fiber material per unit volume in a corresponding section of the right component and is thus determined by the fiber density and the amount of matrix materials.
- a predefined fiber volume content in the sense of the invention may mean, for example, that a certain fiber volume content should be present at least in a section of the right component to be produced. It can also be provided that this fiber volume content is predetermined differently depending on a position on and / or in the braiding component.
- the fiber volume content can be set as constant over the entire legal component.
- a given fiber volume content can be ensured by selecting the amount of matrix material which is used in the computational determination of the wall thickness in step d) of a method according to the invention, in accordance with the fiber density resulting from the simulated braiding.
- a constant fiber volume content can be ensured by assuming a large amount of matrix material in areas of low fiber density corresponding to less matrix material in determining the wall thickness in step d) in areas of high fiber density.
- Such a constant fiber volume content, but also any other given fiber volume content thus results in a variable fiber density in a likewise correspondingly variable wall thickness.
- this geometric shape can be determined such that the resulting braided component has a predetermined, in particular constant or at least substantially constant, fiber volume content.
- Particularly constant properties, in particular constant mechanical properties, of the produced braided component can be ensured thereby.
- topologically identical grid cells are used for the division of the legal position. Topologically identical in the sense of the invention means, in particular, that the individual grid cells are at least similarly designed with respect to their top cover sections of the braiding layer, for example by covering the same number of intersections of threads of the fiber material.
- step c) nodes of fibers of the braiding layer are used as corner points of the grid cells for the division of the braiding layer.
- nodes or intersections of the fibers of the layer of braiding represent particularly suitable locations within the legal position in order to define corner points of the grid cells.
- the underlying simulation performed by the computing unit can be simplified thereby.
- the advantageous provision of topologically identical raster cells already described above can also be made particularly simple by the use of nodes as corner points of the raster cells.
- the assigned grid cells cover an equal number of nodes of fibers of the braided layer top cover, in particular that the divided grid cells cover four nodes, preferably nine nodes, of fibers of the braiding layer.
- the number of overlapped nodes can be chosen in particular such that the divided grid cells are designed to be as small as possible, and on the other hand, the number of divided grid cells is not too large in order not to unnecessarily increase a computational effort in the overall simulation performed.
- a number of four, preferably nine nodes of fibers of the braided layer, which are covered by a respective grid cell, has proven to be particularly favorable.
- step b) a braiding of the braided component body is simulated with several, in particular five or more, legal positions.

- starting points on the surface of the braided component body can be generated by the projection, in particular the vertical projection, of the nodal points on the braided component body. These starting points are distributed in particular over the entire braiding component body, since the nodes of the braiding layer are also distributed throughout the braiding layer.
