Abstract
A fiber-reinforced composite material (11) is constructed by laminating a plurality of fiber bundle layers formed of a reinforced fiber to form a laminated fiber bundle layer and further impregnating the laminated fiber bundle layer with a matrix. At either side of a neutral surface (16), the number of +θ layers which are fiber bundle layers having a fiber orientation angle of +θ and the number of −θ layers which are fiber bundle layers having a fiber orientation angle of −θ are the same, the order of laminating the fiber bundle layers is inversely symmetrical with respect to the standard surface, and the number of other fiber bundle layers disposed between the +θ and −θ layers at either side of the standard surface is the same.
