- the composite component according to one of examples 31 to 37 can optionally have the fabric structure having a warp system and / or at least one weft system with a two-dimensional thread shape extending outside the warp plane or the weft plane.
- the composite component according to one of examples 31 to 38 can optionally have at least some fabric structure elements of the fabric structure configured in such a way that several sections of a fabric structure element each extend away from the fabric layer and thus form the connecting structures.
- the composite component according to one of examples 31 to 39 can optionally have that the component has or consists of a metal material, that the connection structures have or consist of a metal material, and that the component has a welded connection and / or a soldered connection the connection structures is connected.
- the composite component according to one of examples 31 to 40 can optionally have the component having a plurality of through openings which are provided to match the connection structures in such a way that the respective connection structures can extend through respective through openings in the component, so that at least one form-fit connection is formed.

- the composite component according to one of examples 31 to 42 can optionally have that at least some fabric structure elements of the fabric structure are designed to be dimensionally stable.
- Example 44 is a composite component comprising: at least one fabric structure, a component having at least one section which is formed from a matrix material, and connecting structures which are connected to the at least one fabric structure and / or which are formed on the at least one fabric structure, wherein the connection structures each extend into the component in such a way that the at least one section of the component forms a form-fit connection and / or a force-fit connection with the connection structures.
- the composite component according to example 44 can optionally have the matrix material of the component having at least one of the following: a polymer material, an elastomer, a metal material, a ceramic material, a duromer, plaster of paris, concrete, a foam material.
- Example 46 is a component comprising: a fabric layer formed from fabric structure elements which are positively connected to one another, with each adjacent fabric structure elements of the fabric layer being at a first distance from one another, and with at least some of the fabric structure elements being shaped in such a way that they each form a plurality of connecting sections, which extend away from the fabric ply for connecting the fabric ply to a component, each adjacent connecting sections of the plurality of connecting sections having a second spacing from one another which is greater than the first spacing.
- the component according to example 46 can optionally have the connection sections and / or the fabric structure elements in metal material or a fiber composite material or consist thereof.
- the connecting sections can be designed to be dimensionally stable, so that they can be pressed into a matrix material, for example, to make a connection to a component which has or consists of the matrix material into which the connecting sections can be pressed.
- the component according to example 46 or 47 can optionally have the fabric structure elements being designed in the form of a strip.
- the component according to one of examples 46 to 48 can optionally have the connecting sections being formed in that the respective (e.g. band-shaped) fabric structure elements are kinked and / or bent several times.
- the component according to one of examples 46 to 49 can optionally have that at least the fabric structure elements which form the respective connecting sections are dimensionally stable.
- the component according to one of examples 46 to 50 can optionally have the fabric layer being an FHybrid fabric layer, the fabric structure elements being part of a first fabric structure and the FHybrid fabric layer having at least one further fabric structure.
- a composite component can, for example, be a component or a structure with at least two components (e.g. with a Tissue structure and a component, with a first component and a second component, etc.) are understood, which are connected to one another.
- Connection structures as described herein can, for example, be components of the first fabric structure.
- Connecting elements can, for example, already be integrated into the first fabric structure during the production thereof, e.g. the connecting elements can be sections of elongated elements (e.g. threads, tapes, etc.) from which the first fabric structure is formed, e.g. the connecting elements with elongated elements ( e.g. threads, tapes, etc.), from which the first fabric structure is formed, must be physically connected (e.g. glued, welded, etc.).
- the connection structures can only extend away from the first fabric structure on one side, starting from the first fabric structure. In some aspects, the connection structures may not extend through the first fabric structure. It goes without saying that functions, structural configurations, material properties, etc., which are described herein with reference to a composite material, can also be implemented in the same way in a corresponding manufacturing method and vice versa.
