LAMINATED PLATE AND COMPOSITE MOLDED BODY

摘要

Provided is a laminated plate which can be molded and has excellent shape stability after molding even in the case of a laminated plate in which a thin aluminum alloy plate having a substantially lower molding limit is laminated on each of the two sides of a foam core resin having inferior moldability in a single body. A laminated plate (1) has an aluminum alloy plate (2a, 2b) laminated on each of the two sides of a foam core polypropylene resin (3a), and is made into a composite molded body by heating the foam core polypropylene resin (3a) after molding to form the foam. The laminated plate (1) is thin. The aluminum alloy plates (2a, 2b) which make up part of the laminated plate and the foam core polypropylene resin (3a) are also formed to be thin. The aluminum alloy plates (2a, 2b) comprise a thermally-refined material selected from O material, H22 material - H24 material, H32 material - H34 material, and T4 material.
