Abstract

In a preform shaping method, a fiber stack that has a plurality of fiber layers by stacking sheet-form fibrous components is manufactured and a preform that has a configuration in which a first surface and a second surface one or both of which are curved surfaces are coupled is manufactured by bending the sheet-form fibrous components after or while stacking the sheet-form fibrous components. A first sheet-form fibrous component and a second sheet-form fibrous component fiber length directions of which are set to such different directions before a bending process as to be target fiber length directions after the bending process and which form the first surface and the second surface, respectively, after the bending process are disposed in order to form at least one fiber layer of the plurality of fiber layers.
