Abstract

PURPOSE:To prevent bending of fiber during manufacturing process and elevate the productivity by a method wherein a fiber reinforced resin hollow body is formed by winding fiber impregnated with resin around a mandrel, heated and cut. CONSTITUTION:A cylinder 6 is formed as a mandrel 4 furnished with an outer circumferential curvature which comforms to the curvature of a desired leaf spring is rotated around its axis in the direction of A and fiber 5 (carbon fiber, glass fiber, high strength organic fiber, etc.) impregnated with resin is wound around the outer circumferential surface of the mandrel 4 moving it in a proper tension in the directions of B and C. Then, after the mandrel 6 is heated and cured, it is drawn out of the mandrel 4 to shape a hollow cylinder, which is cut in accordance with the width of the leaf spring so as to obtain rings 6'. They are cut to the desired length to obtain leaf springs 6''.
