Abstract

A composite material includes a first component and a second component, each surrounded by a thermoplastic material. The thermoplastic material is joined in a material bond to each of the first component and the second component.

First claim

The invention claimed is:

1. A composite structural material comprising:
a first component surrounded by a first thermoplastic material; and
a second component surrounded by a second thermoplastic material;
wherein a thermoplastic weld joint of the first thermoplastic material and the second thermoplastic material connects the first component and the second component; and wherein
the first component is a metal; and
a first region at an end of the composite structural material and a second region at a central portion of the composite structural material, wherein a quantitative proportion between the first component and the second component in the first region is different than in the second region such that the first region is free of thermoplastic material and the metal is exposed providing a metal welding region.

2. The composite structural material according to claim 1 , wherein the first component comprises a metal wire.

3. The composite structural material according to claim 1 , wherein the second component comprises a fiber.

4. The composite structural material according to claim 3 , wherein the second component comprises a carbon fiber.

5. The composite structural material according to claim 1 , wherein the composite structural material further comprises a transition region between the first region and the second region, and wherein the quantitative proportion of the first component to the second component varies from a first proportion to a second proportion in the transition region at a constant rate.

6. The composite structural material according to claim 1 , wherein the first region and the second region comprises an entire cross section of the composite structural material.

7. The composite structural material according to claim 1 , wherein the composite structural material further comprises a transition region between the first region and the second region, and wherein the quantitative proportion of the first component to the second component varies from a first proportion to a second proportion in the transition region incrementally.

8. The composite structural material according to claim 7 , wherein the first region, the second region and the transition region comprises the entire cross section of the composite structural material.

9. The composite structural material according to claim 1 , wherein the the first region is free of the second component.

10. A motor vehicle comprising a composite structural material according to claim 1 , wherein a welded connection joins the composite structural material and a component of the motor vehicle to form a body or a chassis component of the motor vehicle.
