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

exact text as granted — not AI-modified
What is claimed is:  
     
         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.
