ABSTRACT:
An improved lightweight, flame resistant composite panel is disclosed which is readily shaped at room temperature without the necessity of machining. The composite panel comprises a foamed rigid thermoplastic core sandwiched between a pair of metallic layers. The thermoplastic core contains inorganic fillers in powder form to add further flame resistant characteristics to the composite panel. The metallic layers are bonded to the core by means of a thin layer of adhesive which exhibits good strength at elevated temperatures.
