PROBLEM TO BE SOLVED: To provide a multilayer structure, which enables weight saving and is unlikely to produce protuberant wrinkles or concave portions by buckling at a bending portion even by bending.SOLUTION: There is provided a multilayer structure 4, 5 obtained by laminating a fiber sheet 2 (except a multiaxial fiber sheet unit) and a thermoplastic resin film 3 on at least one principal surface of a hollow plate-shaped body 1 made of a thermoplastic resin. Even when the multilayer structure 4, 5 in which the fiber sheet 2 and the thermoplastic resin film 3 are laminated on the surface of the hollow plate-shaped body 1 is bent, no protuberant wrinkle 6 due to buckling or flexing is formed in the inside. As a whole, the multilayer structure can satisfy both bending rigidity and bending strength while keeping the light weight. |
