Abstract

A composite component composed of a plastics-fiber composite material, having at least two plies of fiber-reinforced material, and at least one electrical line arranged between the at least two plies of fiber-reinforced material.

First claim

What is claimed is:

1. A composite component for a motor vehicle, comprising:
at least two layers composed of a fibre-reinforced material;
electrical terminals spaced apart from one another in the at least two layers;
metal cords of metal wires twisted with one another and arranged between the at least two layers; and
a third layer, arranged between the at least two layers, composed of bi-directional metal cords of metal wires twisted with one another, the third layer including at least one electrical line arranged between the at least two layers of fibre-reinforced material and connected to the electrical terminals, wherein the at least one electrical line is composed of part of the bi-directional metal cords,
wherein the composite component is a reinforced collision impact absorber of a body part of the motor vehicle.

2. The composite component of claim 1 , wherein the electrical terminals are integrated in the composite component.

3. The composite component of claim 1 , wherein the electrical terminals project in the form of electrical lines out of the composite component.

4. The composite component of claim 1 , wherein the fibre-reinforced material comprises carbon-fibre-reinforced material.

5. The composite component of claim 4 , wherein the at least one electrical line directly or indirectly facilitates an electrical connection between at least two composite components via the electrical terminals.

6. A composite component for a motor vehicle, comprising:
electrical terminals spaced apart from one another;
a first layer composed of pre-impregnated, fibre layers of fibre-reinforced material;
a second layer, spaced from the first layer, and which is composed of pre-impregnated, fibre layers of fibre-reinforced material;
a third layer composed of bi-directional metal cords of metal wires twisted with one another and arranged between the first and second layers, the third layer including at least one electrical line which is laid in a continuous fashion between the electrical terminals,
wherein the composite component is a reinforced collision impact absorber of a body part of the motor vehicle.

7. The composite component of claim 6 , wherein the electrical terminals are integrated in the composite component.

8. The composite component of claim 6 , wherein the electrical terminals project in the form of electrical lines out of the composite component.

9. The composite component of claim 6 , wherein the at least one electrical line is composed of twisted and/or braided wires or strands.

10. The composite component of claim 6 , wherein the fibre-reinforced material comprises carbon-fibre-reinforced material.

11. The composite component of claim 6 , wherein the composite component comprises a part of a body of the motor vehicle.

12. The composite component of claim 11 , wherein the at least one electrical line directly or indirectly facilitates an electrical connection between at least two composite components via the electrical terminals.

13. A composite component for a motor vehicle, comprising:
electrical terminals spaced apart from one another;
a first layer composed of pre-impregnated, fibre layers of fibre-reinforced material;
a second layer, and which is composed of pre-impregnated, fibre layers of fibre-reinforced material;
a third layer composed of at least one ply of metal cords of metal wires twisted with one another and arranged between the first and second layers, the third layer including at least one electrical line between the electrical terminals, wherein the metal cords includes first and second metal cords, the first metal cords being arranged perpendicular to the second metal cords to form a metal cord grid,
wherein the composite component is a reinforced collision impact absorber of a body part of the motor vehicle.

14. The composite component of claim 13 , wherein the electrical terminals are integrated in the composite component.

15. The composite component of claim 13 , wherein the electrical terminals project in the form of electrical lines out of the composite component.

16. The composite component of claim 13 , wherein the at least one electrical line is composed of twisted and/or braided wires or strands.

17. The composite component of claim 13 , wherein the fibre-reinforced material comprises carbon-fibre-reinforced material.
