1. A laminated composite vehicle part consisting of:
a pair of metal sheets, and
a polymer disposed in an internal space between the pair of the metal sheets,
wherein the laminated composite comprises one or more connection parts where the pair of the metal sheets are directly connected or welded along the length direction and that do not comprise the polymer,
wherein the laminated composite further comprises one or more reinforcement members connected to the one or more connection parts,
wherein the one or more reinforcement members are external to the internal space and do not span across the internal space,
wherein the polymer comprises poly(fluorene), polyphenylene, polypyrene, polyazulene, polynaphthalene, poly(acetylene), poly(p-phenylene vinylene), poly(pyrrole), polycarbazole, polyindole, polyazepine, polyaniline, poly(thiopene), poly(3,4-ethylenedioxythiopene), or poly(p-phenylene sulfide), or combinations thereof, and
wherein the laminated composite has a width of about 1,200 mm to about 2,000 mm, each of the metal sheets has a thickness of about 0.05 mm to 10 mm, and the polymer disposed in the internal space has a thickness of about 0.05 mm to 10 mm.
