Abstract

The properties of articles fabricated from foamed metals (such as foamed aluminum) are enhanced by coating surfaces thereof with plastic materials, e.g., acrylonitrile-butadiene-styrene polymers. For example, the plastic coating improves the physical properties, and enables the article to be joined to another foamed metal article, or to a metal sheet, wire, glass, rock, or other material. The organic coat gives improved strength to such joint.

Claims

1. AS AN ARTICLE OF MANUFACTURE, A FOAMED METAL BODY HAVING A SURFACE THEREOF COATED WITH A FOAMED ORGANO-POLYMERIC PLASTIC OF SUFFICIENT THICKNESS TO IMPART SHOCK INSULATION PROPERTIES.

2. An article of claim 1 wherein said foamed metal body is foamed aluminum.

3. An article of claim 2 wherein said foamed plastic is foamed polyurethane.

4. An article of claim 2 wherein said foamed plastic is foamed polystyrene.
