Abstract

The present invention provides an arrow shaft including a carbon fiber sheet having a transfer layer formed thereon, wherein the carbon fiber sheet is formed to extend in one direction and includes a plurality of carbon fiber layers in which a camouflage layer is formed on at least a part of an outermost layer thereof, and at least one transfer layer is formed on one surface of at least one of the carbon fiber layer and the camouflage layer.

Claims (29)

1. An arrow shaft comprising a carbon fiber sheet having a transfer layer formed thereon,

wherein the carbon fiber sheet is formed to extend in one direction and includes a plurality of carbon fiber layers in which a camouflage layer is formed on at least a part of an outermost layer thereof, and

at least one transfer layer is formed on one surface of at to least one of the carbon fiber layer and the camouflage layer.

2. The arrow shaft of claim 1 , wherein a resin layer is formed on at least one surface of the camouflage layer and the transfer layer.

3. The arrow shaft of claim 2 , wherein the resin layer includes an adhesive resin at 40 to 50 wt %.

4. The arrow shaft of claim 1 , wherein the transfer layer includes:

a film layer;

a backing agent applied onto the film layer;

a release agent formed on the backing agent;

a white and colored background layer formed at least once; and

a glue sheet layer formed on the background layer.

5. The arrow shaft of claim 4 , wherein the background layer includes a curing agent at 1 to 5 wt %.

6. The arrow shaft of claim 1 , wherein the transfer layer has a brightness of 50% or less with respect to 100% of a brightness of the camouflage layer.

7. The arrow shaft of claim 1 , wherein the transfer layer is formed by performing transfer at least three times.

8. The arrow shaft of claim 7 , wherein the transfer layer has a white-white-white color or a white-pattern-pattern color.

9. The arrow shaft of claim 1 , wherein the transfer layer at least partially includes graphene.

10. The arrow shaft of claim 1 , wherein the camouflage layer includes 70 to 90% cotton and 10 to 30% nylon.

11. The arrow shaft of claim 1 , wherein the transfer layer further includes a reflective material.

12. The arrow shaft of claim 1 , wherein carbon fibers in the plurality of carbon fiber layers are cross-arranged in a direction of 0 to 90 degrees.

13. A method of manufacturing an arrow shaft including a carbon fiber sheet having a transfer layer formed thereon, the method comprising:

sequentially forming an adhesive resin layer and a transfer layer on at least one surface of a carbon fiber sheet including a plurality of carbon fiber layers,

wherein the formation of the transfer layer includes:

applying a backing agent onto at least one surface of a film;

forming a release agent on the backing agent;

forming a white and colored background layer at least once; and

forming a glue sheet layer on the background layer.

14. The method of claim 13 , further comprising forming a camouflage layer on an outer surface of the glue sheet layer of the carbon fiber sheet.

15. The method of claim 14 , wherein an adhesive resin layer and a release layer are sequentially formed on one surface of the camouflage layer.

16. The method of claim 14 , wherein the resin layer includes an adhesive resin at 40 to 50 wt %.
