The present invention provides an improved tubular structure which uses the properties of different materials, such as stiffness, strength, and density are exploited in a manner which combines the most attractive characteristics of existing metal and composite tubes into a metal/composite tube which contains performance characteristics (stiffness, strength or weight) not possible with pure metal or composite materials.For example, an improved tube is suitably created with a conventional metallic tube structure (e.g., steel, aluminum, titanium or the like). The original tube is modified with a secondary operation such as machining, punching, laser cutting or the like to remove various portions of the original tube wall, resulting in a tube with some pattern of “holes” or “cutaway” sections, thus resulting in a lighter tube. The tube is then suitably “fused” with composite material. For example, in one embodiment of the present invention, the metal piece is placed in a mold assembly and composite materials are molded inside the metal tube resulting in a part metal and part composite tube that has beneficial characteristics of each material.

1. A tubular structure, comprising a substantially cylindrical metal tube, having a wall with a series of apertures, a composite material placed therewithin, wherein said composite material is contiguous with an inner surface of said wall of said metal tube and an inner sleeve within said composite material.2. A tubular structure according to claim 1, wherein each of said apertures have substantially the same shape.3. A tubular structure according to claim 1, wherein said apertures are substantially symmetrical to one another.4. A tubular structure according to claim 1, wherein said composite material extends through said apertures.5. A tubular structure according to claim 1, wherein said metal tube has an outer surface defining an outer plane and wherein said composite material extends through said apertures a distance such that an outer surface of said portion of said composite material extending through said aperture is contiguous with said outer plane.6. A tubular structure according to claim 1, wherein said apertures have a diamond shape.7. A composite structure, comprising an outer structure with at least one outer wall that at least partially enclose a volume, said outer structure having a series of apertures, and a composite material placed on an inner side of said outer structure, wherein said composite material is contiguous with said inner surface, and an inner sleeve within said composite material, and wherein said outer structure has an outer surface defining an outer plane and wherein said composite material extends through said apertures a distance such that an outer surface of said portion of said composite material extending through said aperture is contiguous with said outer plane.8. A composite structure according to claim 7, wherein each of said apertures have substantially the same shape.9. A composite structure according to claim 7, wherein said apertures are substantially symmetrical to one another.10. A composite structure according to claim 7, wherein said composite material extends through said apertures.
