Abstract
A method for producing a stepped semi-hardened product having a joggle in an edge portion, comprising: the first process where a plurality of first sheets made of a fiber-reinforced composite are laminated to each other, heated under a pressure and cooled under a pressure to provide a first flat plate-shaped laminate; the second process where the first flat plate-shaped laminate is softened by heating, placed on a first forming tool and formed by cooling under a pressure to prepare a simple shaped intermediate; and the third process where an edge portion of the simple shaped intermediate is heated under a pressure to form said joggle. A method for producing a preformed structure composed of the stepped semi-hardened product and a simple shaped semi-hardened product is also provided.
