Abstract

An arrow shaft composed of a non-elastic fiber and a low elastic fiber and a method for manufacturing the same are disclosed. The method comprises the steps of spreading an elastic sheet such as pre-impregnated or prepreged carbon or glass fiber, adhering a non-elastic or low elastic fiber, preferably a prepreged pre-impregnated natural, synthetic, or glass fiber onto the elastic sheet, winding them onto a mandrel, and carrying out tapping, heat treating/cooling, releasing, and polishing processes.

Claims

1. An arrow shaft manufactured by a method claiming:

layering and winding an elastic sheet around a peripheral surface of a mandrel;

when the elastic sheet is layered on the peripheral surface of the mandrel, layering a non-elastic sheet on an outermost surface of the elastic sheet; and

winding the elastic sheet around the mandrel together with the non-elastic sheet.

2. An arrow shaft according to claim 1, wherein the non-elastic sheet is a sheet made of a fibroid material.

3. An arrow shaft according to claim 2, wherein the non-elastic sheet comprises a natural fiber, cotton, and a chemical fiber.

4. An arrow shaft according to claim 1, wherein the non-elastic sheet is painted to have various designs.

5. An arrow shaft made of an elastic sheet, the arrow shaft comprising:

a non-elastic sheet adhered on an peripheral surface of the elastic sheet.

6. An arrow shaft as claimed in claim 5, wherein the non-elastic sheet comprises a natural fiber, cotton, and a chemical fiber.

7. An arrow shaft as claimed in claim 5, wherein the elastic sheet carbon or glass fiber.
