Abstract

A vehicle body component includes a basic element reinforced with a reinforcing element of fiber-reinforced plastics material. The basic element reinforced with the reinforcing element is a basic element of a pillar of a vehicle body or a roof element. The reinforcing element has a constant thickness or a variable thickness.

First claim

What is claimed is:

1. A vehicle body component comprising:
a basic element;
a reinforcing element reinforcing the basic element, the reinforcing element being a fiber-reinforced plastics material and being joined form-fittingly at least in discrete locations to the basic element with at least one friction stir welded joint that joins the reinforcing element directly to a base, a flange, or a flank of the basic element without disturbing any fibers within the reinforcing element,
wherein the basic element is a pillar of a vehicle body or a roof element of a vehicle,
wherein the reinforcing element is bonded to the basic element by an adhesive layer that extends along the base and the flange of the basic element.

2. The vehicle body component according to claim 1 , wherein the adhesive layer extends along substantially an entire region in which the reinforcing element overlaps the basic element.

3. The vehicle body component according to claim 1 , wherein the basic element is selected from the group consisting of a formed metal sheet and a casting.

4. The vehicle body component according to claim 1 , wherein the basic element is a steel material.

5. The vehicle body component according to claim 1 , wherein the reinforcing element is selected from the group consisting of a carbon fiber-reinforced plastics material and a glass fiber-reinforced plastics material.

6. The vehicle body component according to claim 1 , wherein an active side of the basic element is flat after friction stir welding.

7. The vehicle body component according to claim 1 , wherein the reinforcing element is arranged on an inside of the basic element.

8. The vehicle body component according to claim 1 , wherein the reinforcing element is arranged on an outside of the basic element.

9. The vehicle body component according to claim 1 , wherein the reinforcing element has a constant thickness.

10. The vehicle body component according to claim 1 , wherein the reinforcing element has a variable thickness.

11. A vehicle body component comprising:
a basic element including a pair of first flanks and a first base that define a generally U-shaped central member;
a reinforcing element reinforcing the basic element, the reinforcing element being a fiber-reinforced plastics material and being joined form-fittingly at least in discrete locations to the basic element, the reinforcing element including a pair of second flanks and a second base that define a generally U-shaped reinforcement body nested with the generally U-shape of the central member so that the first base contacts the second base and each first flank contacts one of the second flanks, the reinforcement body joined to the basic element by at least one friction stir welded joint and an adhesive,
wherein the basic element is a pillar of a vehicle body or a roof element and is a material selected from the group consisting of steel, aluminum, and magnesium.

12. The vehicle body component according to claim 11 , wherein the adhesive bonds the first base to the second base and bonds at least one of:
a) the first flanks to the second flanks; and
b) a pair of first flanges to a pair of second flanges, wherein the first flanges extend laterally outward from an inboard side of each first flank and the second flanges extend laterally outward from an inboard side of each second flank.

13. The vehicle body component according to claim 11 , wherein the second base and the second flanks are nested inside the first base and first flanks of the basic element.

14. The vehicle body component according to claim 11 , wherein the first base and the first flanks are nested inside the second base and the second flanks of the reinforcing element.

15. The vehicle body component according to claim 11 , wherein the reinforcing element has a constant thickness.

16. The vehicle body component according to claim 11 , wherein the reinforcing element has a variable thickness.

17. The vehicle body component according to claim 11 , wherein the reinforcing element is selected from the group consisting of a carbon fiber-reinforced plastics material and a glass fiber-reinforced plastics material.

18. A vehicle body component comprising:
a basic element comprising a material selected from the group consisting of steel, aluminum, and magnesium, the basic element including a pair of first flanges, a pair of first flanks, and a first base, the first flanks being spaced apart on opposite sides of a longitudinal axis of the basic element, the first base extending laterally between an outboard side of the first flanks to define a generally U-shaped central member, the first flanges extending laterally outward from an inboard side of the first flanks;
a reinforcing element comprising a fiber-reinforced plastics material consisting of fibers and a matrix, the reinforcing element including a pair of second flanks and a second base, the second flanks being spaced apart on opposite sides of the longitudinal axis of the basic element and overlapping corresponding ones of the first flanks, the second base extending laterally between an outboard side of each second flank and overlapping the first base to define a generally U-shaped reinforcement body nested with the U-shaped central member, the reinforcement body being joined to the first base, the first flanges, or the first flanks by at least one friction stir welded joint, the reinforcement body extending longitudinally along a region of the U-shaped central member that is less than an entire longitudinal length of the U-shaped central member and being bonded to the U-shaped central member with an adhesive,
wherein the matrix of the reinforcing element is melted at the stir welded joint and the fibers are undamaged.

19. The vehicle body component according to claim 18 , wherein the adhesive bonds the first flanks to the second flanks and the first base to the second base.

20. The vehicle body component according to claim 18 , wherein the reinforcing element has a variable thickness.
