Abstract

An automobile chassis and a one-piece body integrated into a unitary structure, and a method for fabricating, assembling and integrating the chassis and body. The body includes interior panels, a cockpit, an engine enclosure module, and an underbody. The chassis/body structure, comprised of a single type of aluminum alloy and a single type of thermoplastic, is resistant to high-stress loads and is substantially recyclable into industrial-quality constituents. A first preferred embodiment includes a body rotomolded from a reinforced polycarbonate, polycarbonate/ABS blend, or polyimide thermoplastic, seven aluminum alloy bulkheads, and stacks of thin-wall aluminum honeycomb-cell panels embedded in an unreinforced foam of the thermoplastic. A second preferred embodiment includes a body rotomolded from a reinforced liquid crystal polymer thermoplastic, seven aluminum alloy bulkheads, and stacks of thin-wall aluminum honeycomb panels. A third preferred embodiment includes a body rotomolded from a reinforced polycarbonate thermoplastic, seven aluminum alloy bulkheads, and aggregated sub-assemblies of polycarbonate micro-honeycomb blocks having cells filled with a foam of the unreinforced polycarbonate thermoplastic.
