9-4739). Further, a composite plate in which a metal plate is bonded to both surfaces of a foamed plastic is also known (for example, see Japanese Patent Publication No. 7-90621). This type of composite plate has the properties of both a metal and a synthetic resin, and thus is lightweight. It has various features such as resistance, impact resistance, and ease of processing. Applications include building materials, interior / exterior members and others, and various improvements suitable for each application have been made.

圧強度低下の問題が生じる。In order to improve the lightness, heat resistance and heat insulation of the composite plate, it has been considered to use a foamed resin by foaming a synthetic resin as a core material. However, since the metal plate on the surface is relatively thin, if the inside is soft foamed resin, the metal surface of the composite plate will be dented or open if a pressing force or impact force is applied to it. The problem of strength reduction occurs.

いた。[0004] For example, if a synthetic resin such as polyethylene is used and the expansion ratio is set to 1.3 times or more, the surface pressure strength of the composite plate is reduced so as not to be practically used. For this reason, it has been considered to improve the surface pressure strength by interposing a reinforcing layer made of non-foamed resin between the foamed resin and the metal plate, but further improvement of the surface pressure strength is expected depending on the application. It is rare. In order to increase the surface pressure strength, it is conceivable to make the metal plate thicker, but there is a problem that the weight increases and the price increases,
There has been a demand for a composite plate that simultaneously satisfies both lightness and high strength.
