Abstract

A composite tubeshaft comprising a composite substrate defined by a first surface and a second surface; and a metallic substrate having at least two teeth. The teeth of the metallic substrate engage the composite substrate such that at least one tooth is positioned over the first surface and at least one tooth is positioned over the second surface.

Claims (17)

1. A vehicle composite tubeshaft assembly comprising:

a composite substrate defined by a first surface and a second surface; and

a metallic substrate having at least two teeth, wherein the teeth engage the composite substrate and at least one tooth of the at least two teeth is positioned over the first surface while at least one tooth of the at least two teeth is positioned over the second surface to engage the metallic substrate to the composite substrate, wherein the composite substrate and the metallic substrate are rolled to create the vehicle composite tubeshaft assembly.

2. The vehicle composite tubeshaft assembly of claim 1 further including a securing agent to bond the metallic substrate to the composite substrate.

3. The vehicle composite tubeshaft assembly of claim 1 wherein the metallic substrate includes a region that attaches the composite tubeshaft to a torque transmitting element.

4. The vehicle composite tubeshaft assembly of claim 3 wherein the region includes a base such that the at least two teeth extend from the base and are positioned over the first and second surfaces of the composite substrate.

5. The vehicle composite tubeshaft assembly of claim 1 wherein the teeth of the metallic substrate are serrated.

6. The vehicle composite tubeshaft assembly of claim 1 wherein the metallic substrate includes apertures.

7. The vehicle composite tubeshaft assembly of claim 1 wherein the metallic substrate includes barbs.

8. The vehicle composite tubeshaft assembly of claim 1 wherein the teeth are equally spaced equidistant from each other.

9. A method of producing a vehicle composite tubeshaft assembly comprising:

positioning a planar composite substrate;

positioning a metallic substrate having at least two teeth that are generally planar relative to the composite substrate;

positioning one of the at least two teeth of the metallic substrate on a first surface of the composite substrate and another one of the at least two teeth of the metallic substrate on a second surface of the composite substrate such that an end of the composite substrate is attached to a base of the metallic substrate;

applying a securing agent to the at least two teeth of the metallic substrate and the composite substrate;

rolling the composite and the metallic substrates to form a tubeshaft; and

curing the tubeshaft.
