CONSTITUTION: A composite arrow shaft having an aluminum sheet layer comprises a carbon fiber sheet(111), an aluminum sheet(112), and a fiber sheet. The carbon fiber sheet is formed by piling up multiple carbon fibers unit sheets across each other. The aluminum sheet is loaded on the outer surface of the carbon fiber sheet. The fiber sheet is loaded on the outer surface of the aluminum sheet. The fiber sheet is formed by processing a fiber texture with printed or transferred with patterns.
