Abstract
A double sheet aluminum panel has a first layer of a first aluminum material attached to a second layer of a second aluminum material by an adhesive, such as a thermosetting polymer disposed there between, producing a non-flammable panel. In a method for making the panel, the adhesive is applied to one or both sheets of aluminum, heated, then pressure rolled to distribute the adhesive into a thin film that bonds the two layers of aluminum together. The layers may be of the same or different composition and thickness and may be subjected to anodization and conversion coating.
Claims25
A panel, comprising a first layer of a first aluminum material, a second layer of a second aluminum material disposed substantially parallel to the first layer, an adhesive disposed between the first layer and the second layer, attaching the first layer to the second layer.
A method for making a panel, comprising the steps:
- (A) providing a first sheet of a first aluminum material;
- (B) providing a second sheet of a second aluminum material;
- (C) applying an adhesive to at least one surface of the first or second sheets;
- (D) roll bonding the first and second sheets together with the adhesive there between to form a laminate sheet with the first and second sheets attached to each other by the adhesive;
- (E) cutting the laminate sheet into panels.
