Abstract

A reinforced archery arrow shaft includes a tubular core, with an attached fabric sleeve covering the core. The core may include carbon therein. The sleeve is formed from a fabric material, which is wrapped around and affixed to the core. Preferably, the sleeve fabric carries a decorative design or pattern on the exterior surface thereof. In a method of making an arrow, a piece of fabric is placed covering a hollow tubular core, and is affixed thereto. Then, a resin or protective composition, associated with the fabric material, is cured to adhere the fabric to the core. The resin may be impregnated into the fabric prior to its placement on the core, or alternatively, may be applied to the fabric by conventional methods such as spraying, dipping, brushing, or powder coating. The shaft may be treated to make the exterior surface smooth after curing. Optionally, accessories may be attached to the arrow shaft to form an arrow.

Claims

1. An arrow shaft, comprising:

a hollow, substantially fabric-free tubular core which is adapted to be formed into an arrow shaft, said tubular core having a wall thickness and surrounding a central chamber with a diameter measuring more than twice the core wall thickness, said core comprising carbon;

a fabric sleeve covering and affixed to the core; and

an adhesive associated with the fabric sleeve;

wherein the adhesive helps to adhere the fabric sleeve to the core.

2. The arrow shaft of claim 1, wherein the fabric sleeve has a design or pattern thereon.

3. The arrow shaft of claim 1, wherein the exterior of the fabric sleeve is treated to form a smooth surface on an exterior surface thereof.

4. The arrow shaft of claim 1, wherein said adhesive material is selected from the group consisting of urethanes, varnishes, lacquers, epoxies, paints, and powder coatings.

5. The arrow shaft of claim 1, wherein the arrow shaft further comprises a fiberglass layer.

6. An arrow shaft, comprising:

a hollow, substantially fabric-free tubular core which is adapted to be formed into an arrow shaft, said tubular core having a first end with a first diameter, and a second end opposite the first end, the second end having a second diameter which is substantially equal to the first diameter, said tubular core having a wall thickness and surrounding a central chamber with a diameter measuring more than twice the core wall thickness, said core comprising carbon;

a fabric sleeve covering and affixed to the core; and

an adhesive associated with the fabric sleeve or with the core;

wherein the adhesive helps to adhere the fabric sleeve to the core.

7. The arrow shaft of claim 6, wherein the fabric sleeve has a design or pattern thereon.

8. The arrow shaft of claim 6, wherein the exterior of the fabric sleeve has a smooth exterior surface, said smooth exterior surface being a result of a grinding operation.

9. The arrow of claim 6, wherein said adhesive is selected from the group consisting of urethanes, varnishes, lacquers, epoxies, paints, and powder coatings.

10. The arrow shaft of claim 6, wherein the tubular core has a substantially constant diameter between the first end and the second end thereof.

11. The arrow shaft of claim 6, wherein the fabric is a nonwoven fabric.

12. The arrow shaft of claim 6, wherein the fabric is a woven fabric.

13. The arrow shaft of claim 6, wherein the fabric is substantially rectangular in shape.

14. The arrow shaft of claim 13, wherein the fabric is situated on the core with opposed side edges thereof in abutting relation.

15. The arrow shaft of claim 13, wherein the fabric is situated on the core with opposed side edges thereof overlapping one another.

16. An arrow shaft, comprising:

a hollow, substantially fabric-free tubular core which is adapted to be formed into an arrow shaft, said tubular core having a wall thickness and surrounding a central chamber with a diameter measuring more than twice the core wall thickness, said core comprising carbon;

a fabric sleeve covering and affixed to the core; and

an adhesive associated with the fabric sleeve or with the core;

wherein the exterior of the fabric sleeve has a smooth exterior surface, said smooth exterior surface being a result of a grinding operation.

17. The arrow shaft of claim 16, wherein the fabric sleeve has a design or pattern thereon.

18. The arrow shaft of claim 16, wherein the tubular core has a first end with a first diameter, and a second end opposite the first end, the second end having a second diameter which is substantially equal to the first diameter, and the shaft having a substantially constant diameter between the first end and the second end thereof.

19. The arrow shaft of claim 16, wherein the fabric is a nonwoven fabric.

20. The arrow shaft of claim 16, wherein the fabric is a woven fabric.

21. The arrow shaft of claim 16, wherein the fabric is substantially rectangular in shape.

22. The arrow shaft of claim 21, wherein the fabric is situated on the core with opposed side edges thereof in abutting relation.

23. The arrow shaft of claim 21, wherein the fabric is situated on the core with opposed side edges thereof overlapping one another.

24. An arrow shaft, consisting essentially of:

a hollow, substantially fabric-free tubular core comprising a carbon composite material, said tubular core having a wall thickness and surrounding a central chamber with a diameter measuring more than twice the core wall thickness;

a fabric sleeve covering and affixed to the core; and

an adhesive resin material associated with the fabric sleeve;

wherein the resin helps to adhere the fabric sleeve to the core.
