COMPOSITE STRUCTURAL MEMBER

摘要

COMPOSITE STRUCTURAL MEMBERThere is provided a composite structural member having high rigidity even at a small thickness, the composite structural member being easily attachable to a target object. A composite structural member lA includes a metal base material 10A, a resin formed article 11, and a resin film layer 12 that covers a surface of the metal base material 10A. The metal base material 10A is a plastically formed material formed by subjecting a flat sheet material having a thickness of 50 µm or more to press forming. The metal base material 10A and the resin film layer 12 are joined together using a constituent resin of the resin formed article 11. The composite structural member IA includes the metal base material 10A and thus can have excellent strength and rigidity even at a smaller thickness. The composite structural member lA includes the resin formed article 11. An attaching portion to the target object can be easily formed in the resin formed article 11. Thus, the composite structural member lA has excellent mounting workability. The composite structural member lA includes the resin film layer 12 and thus has excellent design properties.Figure 1
