Abstract

The present invention pertains inter alia to a method for producing a component for connecting structures at crossing regions thereof, having the following steps: depositing first and second fibers on an underlay in such a way that a respective first fiber has an offset in the longitudinal direction of the first or second fiber with respect to a respective second fiber; connecting the first and second fiber along an overlap region, in which the first and second fibers overlap; and pivoting the first and second fibers with respect to one another to form the component.

First claim

What is claimed is:

1. A method for producing a component for connecting structures at crossing regions thereof, the method comprising:
depositing first fibres and second fibres on an underlay, wherein the first fibres and the second fibres are deposited in a direction transverse to a longitudinal direction of the underlay and in parallel to each other, such that each respective first fibre has an offset in the longitudinal direction of the first fibres or the second fibres with respect to each respective second fibre producing a first and second projection region, wherein the first projection region only has ends of the first fibres and the second projection region only has ends of the second fibres;
connecting the first fibres and the second fibres along a region between the first and second projection regions; and
pivoting the first fibres and the second fibres with respect to one another to form the component.

2. The method according to claim 1 , wherein the first fibres are connected to one another in the first projection region, in which they project in the longitudinal direction over the second fibres, and/or the second fibres are connected to one another in the second projection region, in which they project in the longitudinal direction over the first fibres.

3. The method according to claim 1 , wherein the first fibres and the second fibres are connected to one another in the overlap region along a centre line, which is arranged centrally in relation to a total extent of the first fibres and the second fibres in the longitudinal direction, and/or the first fibres are connected to one another in the first projection region along a first line parallel to the centre line and/or the second fibres are connected to one another along a second line parallel to the centre line and opposing the first line in relation to the centre line.

4. The method according to claim 1 , wherein the first fibres and the second fibres are connected to one another in the overlap region, the first fibres are connected to one another in the first projection region and/or the second fibres are connected to one another in the second projection region by stitching, weaving, braiding or gluing.

5. The method according to claim 4 , wherein at least one stitching, weaving or braiding fibre is fed through a gap in the underlay.

6. The method according to claim 4 , wherein the gluing takes place by a thermoplastic strand, a fibre sheathed at least in portions with a thermoplastic material, or an adhesive strip.

7. The method according to claim 1 , wherein the first fibres and the second fibres are pivoted with respect to one another in such a way that they have an angle of 30 to 90 degrees with respect to one another, and/or the pivoting of the first fibres and the second fibres with respect to one another is brought about by a curved guide element, past which the first fibres and/or the second fibres are guided.

8. The method according to claim 1 , wherein the underlay is configured as a conveyor belt, on which the first and second fibres are deposited.

9. The method according to claim 1 , wherein the first fibres and the second fibres are in each case cut to length from continuous material before being deposited.

10. A method for producing a structural arrangement for an aircraft or spacecraft, the method comprising:
providing a first structure;
providing a second structure, which forms a crossing region with the first structure;
producing a component by a method according to claim 1 ; and
connecting the first and second structure at the crossing region by the component.
