Abstract

A component includes at least first and second plastics component parts which are interconnected in a connection zone. A reinforcing element includes at least one wire which bridges the connection zone. The first and second plastics component parts are welded together and/or are fused together in the connection zone. The plastics component parts may be bonded to one another.

First claim

The invention claimed is:

1. A component comprising:
at least first and second plastics component parts interconnected in a connection zone such that the first and second plastics component parts overlap in the connection zone; and
a reinforcing element comprising at least one wire extending through the connection zone and embedded at least partially in the first and second plastics component parts in the connection zone,
wherein the at least one wire comprises a plurality of connected helical wires interwoven in the form of a mat, and
wherein the at least one wire on surfaces of the first and second plastics component parts opposite the connection zone does not protrude beyond said first and second plastics component parts and/or is not visible on said surfaces.

2. The component according to claim 1 , wherein the first and second plastics component parts are welded together and/or are fused together in the connection zone.

3. The component according to claim 1 , wherein the first and second plastics component parts are bonded to one another.

4. The component according to claim 1 , wherein the at least one wire comprises a plurality of identical turns and individual turns have a uniform thickness in a component transverse direction, wherein the plurality of wires are arranged next to one another and form a planar structure having a uniform thickness.

5. The component according to claim 1 , wherein at least one of the first and second plastics component parts comprises fibres arranged between individual turns or portions of the reinforcing element, the fibres being directional fibres serving to increase a load-bearing capacity of the component in one or more directions.

6. A joining method for producing a connection between at least two plastics component parts, the method comprising:
arranging a wire-shaped reinforcing element between the at least first and second plastics component parts interconnected in a connection zone such that the first and second plastics component parts overlap in the connection zone; and
softening and/or melting at least one of the first and second components by supplying energy so that portions of the reinforcing element embedded in the material of the component are integrally bonded to one another,
wherein the wire-shaped reinforcing element extends through the connection zone and is embedded at least partially in the first and second plastics component parts in the connection zone,
wherein the wire-shaped reinforcing element on surfaces of the first and second plastics component parts opposite the connection zone does not protrude beyond said first and second plastics component parts and/or is not visible on said surfaces, and
wherein the at least one wire comprises a plurality of connected helical wires interwoven in the form of a mat.

7. The joining method according to claim 6 , wherein the reinforcing element is heated such that the reinforcing element dissipates thermal energy to the surrounding plastics component parts.

8. The component according to claim 1 , wherein the reinforcing element is bent.

9. The component according to claim 5 , wherein both the first and second plastics component parts comprise fibres arranged between individual turns or portions of the reinforcing element.

10. The component according to claim 5 , wherein the fibres are directional fibres.

11. The component according to claim 9 , wherein the fibres are directional fibres.

12. The component according to claim 10 , wherein the directional fibres serve to increase the load-bearing capacity of the component in one or more directions.

13. The component according to claim 11 , wherein the directional fibres serve to increase the load-bearing capacity of the component in one or more directions.

14. The joining method according to claim 6 , wherein the reinforcing element is bent.

15. The joining method according to claim 6 , wherein portions of the reinforcing element embedded in the plastics component parts are integrally bonded to one another.

16. The joining method according to claim 6 , wherein supplying energy comprises supplying inductive energy, electrical energy or microwave energy.

17. A component, comprising:
at least first and second plastics component parts interconnected in a connection zone such that the first and second plastics component parts overlap in the connection zone; and
a reinforcing element comprising at least one wire bridging extending through the connection zone and embedded at least partially in the first and second plastics component parts in the connection zone,
wherein the at least one wire comprises a plurality of connected helical wires interwoven in the form of a mat,
wherein the component is a component of a flap of an aircraft.
