<P>PROBLEM TO BE SOLVED: To improve yield, to facilitate arrangement of reinforced fiber in the longitudinal direction, and to increase density of the reinforced fiber in the longitudinal direction, when forming a dry preform by winding the reinforced fiber around an outer periphery of a mandrel. <P>SOLUTION: While the long mandrel 2 is sent to one side in the longitudinal direction, the reinforced fiber (a fiber bundle T1) aligned along the longitudinal direction is supplied to the outer periphery of the mandrel 2 to form a longitudinal reinforced fiber layer 11 covering the circumference of the mandrel 2. The reinforced fiber (fiber bundles T2, T3) is spirally wound around the outer periphery of the mandrel 2 to form spiral reinforced fiber layers 12, 13 covering the circumference of the mandrel 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
