ABSTRACT:
A recyclable, low cost, collision-resistant automobile chassis and body and method for fabricating the same. The method of manufacture comprises; fabricating a plurality of generally planar bulkheads from a metal alloy; disposing the bulkheads in a generally and mutually parallel orientation, each bulkhead perpendicular to and aligned generally transversely and symmetrically relative to a common central horizontal longitudinal axis; fabricating a plurality of chassis segments from the metal alloy, each segment comprising a multiplicity of spaced hollow cells fixed at one end in a common surface; interposing and rigidly attaching at least one of said pluralities of chassis segments between respective bulkheads to form a plurality of chassis sections, a section defined as the portion of the fabricated chassis between two adjacent bulkheads; and permeating the plurality of chassis sections with liquefied polymer between and around said hollow cells.
