A composite structure comprises a cover plate and a plate-like fiber layer, one side of the plate-like fiber layer being fastened to one side of the cover plate with a solder at contact points of fibers of the plate-like fiber layer and the cover plate. Contacting fibers of the plate-like fiber layer are connected to each other with the solder in the plate-like fiber layer. A vehicle having a composite structure and a method of manufacturing a composite structure are furthermore disclosed.

A thermoplastic molded product including a decorative material having superior heat resistance, impact strength and flexural strength is disclosed. The thermoplastic molded product is useful for a window glass substitute, a partition, a decorative panel, a decorative film, and so on. The thermoplastic molded product comprises a copolymerized polyester resin sheet made of a copolymerized polyester resin; and at least one decorative material laminated on the copolymerized polyester resin sheet, the lamination being performed by applying heat and pressure to the copolymerized polyester resin sheet and the decorative material. The copolymerized polyester resin has an alternating structure of acid moieties which are derived from acid components and diol moieties which are derived from diol components, and the acid components comprise terephthalic acid, and the diol components comprise (i) 599 mol % of 1,4-cyclohexanedimethanol and (ii) 160 mol % of isosorbide with respect to the total diol components.
