Abstract

The invention is directed to an arrow system having a shaft having a first end and an insert receptive of a standard point, the insert being disposed completely within the first end of the shaft. An insert installation tool may be used as part of the invention to facilitate insertion of the insert into the first end of the shaft. The invention further includes a reduced diameter hunting arrow shaft that maintains sufficient spine and weight characteristics. The reduced diameter hunting arrow shaft is receptive of standard or non-standard internal components for increasing arrow penetration and shot accuracy. Still further, the invention includes an arrow tip assembly including a male insert and a female point to assist in aligning points with arrow shafts. The arrow shaft is in one embodiment an aluminum-carbon arrow which includes a metallic core and an outer fiber reinforced polymer layer.

Claims

1. An aluminum-carbon arrow, comprising:

a metallic core having a front end portion;

a fiber reinforced polymer layer disposed about the metallic core;

an insert receptive of a point disposed completely within the front end portion.

2. An aluminum-carbon arrow according to claim 1 wherein the point comprises a shoulder and the shaft comprises a front end wall, and wherein the insert is seated at a depth within the shaft such that the shoulder of the point bears against the front end wall of the shaft when the point is fully engaged with the insert.

3. An aluminum-carbon arrow according to claim 1, wherein an outer diameter of the fiber reinforced polymer layer comprises a standard aluminum arrow size.

4. An aluminum-carbon arrow according to claim 1 wherein an outer diameter of the fiber reinforced polymer layer is less than or equal to approximately 0.275 inches.

5. An aluminum-carbon arrow according to claim 1 wherein an inner diameter of the metallic core is approximately 0.200 inches.

6. An aluminum-carbon arrow according to claim 1 wherein the metallic core comprises an aluminum tube.

7. An aluminum-carbon arrow according to claim 1 wherein the fiber reinforced polymer layer comprises carbon.

8. An arrow system, comprising:

an aluminum carbon composite arrow shaft having an outside diameter of 0.275 inches or less;

an insert receptive of a point disposed completely within a front end portion of the carbon aluminum arrow shaft, wherein the point comprises a shoulder and the carbon aluminum arrow shaft comprises a front end wall;

wherein the insert is seated at a depth within the arrow shaft such that the shoulder of the point bears against the end wall of the shaft when the point is fully engaged with the insert.

9. A method of making an aluminum-carbon arrow, comprising:

providing an aluminum core tube;

covering the aluminum core tube with a fiber reinforced composite;

inserting an insert completely within the aluminum core tube.

10. A method of making an aluminum-carbon arrow according to claim 9, further comprising connecting a point to the insert.

11. A method of making an arrow according to claim 9, further comprising:

attaching a point to the insert;

bearing a shoulder of the point directly against a front end wall of the aluminum core tube.
