Document Type and Number:
WIPO Patent Application WO/2014/175331
Kind Code:
A1
Abstract:
A composite structure obtained from a thin-sheet metal and a foamable resin is provided, the composite structure attaining a weight reduction and having intact mechanical properties. Also provided is a process for producing the composite structure.
This composite structure comprises: one thin-sheet metallic object which was obtained by forming a thin-sheet metallic material having a given thickness into a desired three-dimensional shape and in which the inner surface part was subjected to a treatment such as primer coating or resin laminating; another thin-sheet metallic object which was obtained by forming a thin-sheet metallic material having a given thickness into a desired three-dimensional shape and in which the inner surface part was subjected to a treatment such as primer coating or resin laminating, said another thin-sheet metallic object having been disposed so that the inner surface part thereof faces that of said one thin-sheet metallic object; and a foamed resinous object formed by packing the inner space between the inner surface part of said one thin-sheet metallic object and the inner surface part of said another thin-sheet metallic object with a foamable resin composition and making the composition foam during the packing to fill the inner space, the foamed resinous object having been integrated with the surfaces that underwent a treatment, such as primer coating or laminating, and having been tenaciously bonded to both said one thin-sheet metallic object and said another thin-sheet metallic object.
