Abstract

Composite tube assemblies comprising a composite tube comprising a distal end having a first conical section and a second conical section, wherein a distal end of the first conical section is in contact with a proximal end of the second conical section having the same outer diameter as the distal end of the first conical section, wherein a proximal end of the first conical section and a distal end of the second conical section have a smaller outer diameter than the distal end of the first conical section, a locking ring disposed around the first conical section, an end fitting disposed around the second conical section, wherein the end fitting is coupled to the locking ring, and a retaining ring circumferentially disposed around the locking ring are provide.

First claim

What is claimed is:

1. A composite tube assembly comprising:
a composite tube comprising a distal end having a first conical section and a second conical section,
wherein a distal end of the first conical section is in contact with a proximal end of the second conical section having the same outer diameter as the distal end of the first conical section,
wherein a proximal end of the first conical section and a distal end of the second conical section have a smaller outer diameter than the distal end of the first conical section;
a locking ring disposed around the first conical section;
an end fitting disposed around the second conical section and internal to the composite tube, wherein the end fitting is coupled to the locking ring; and
a retaining ring circumferentially disposed around the locking ring.

2. The composite tube assembly of claim 1 , wherein the end fitting is coupled to the locking ring with retention bolts.

3. The composite tube assembly of claim 1 , wherein the locking ring comprises a plurality of pieces.

4. The composite tube assembly of claim 1 , wherein the retaining ring comprises carbon fiber.

5. The composite tube assembly of claim 1 , wherein the retaining ring comprises a metal.

6. The composite tube assembly of claim 1 , wherein the first conical section and the second conical section are nanocoated.

7. The composite tube assembly of claim 1 , wherein the first conical section and the second conical section comprise a metallic insert.

8. The composite tube assembly of claim 7 , wherein the metallic insert is co-molded with the composite tube.

9. The composite tube assembly of claim 7 , wherein the metallic insert is bonded with the composite tube.

10. The composite tube assembly of claim 7 , wherein the metallic insert is co-cured with the composite tube.

11. The composite tube assembly of claim 1 , wherein the outer diameter of the distal end of the second conical section is the same size as the proximal end of the first conical section.
