<p>PROBLEM TO BE SOLVED: To provide a laminated pipe applicable to a shake-out type rod and a connection type rod by strengthening its elasticity and decreasing its weight while its flexural strength is kept. SOLUTION: The laminated tube is composed of an inside tube, a hollow structure part, and an outside tube. The inside tube is made by laminating an innermost layer 11 and an inner layer 12 coaxially, and the outside tube is made by laminating a cylindrical outer layer 14 and an outermost layer 15 coaxially. The hollow structure part is formed integrally between the outside tube and the inside tube to have the shape of a rib. An intermediate member 13 is set in the circumferential direction of the laminated tube at equal intervals spirally. The innermost layer 11, the inner layer 12, and the intermediate member 13 are formed by using carbon fibers. The outer layer 14 and the outermost layer 15 can be formed by using carbon fibers, but, when they are formed by using transparent glass fibers, the decorativity of the tube can be improved.</p> |
