a hollow container for storage and transport of fluid hydrocarbon vehicular fuels is composed of a laminated structure of polymeric resin body component and electrodeposited metal . an interior stratum of polymer chemically resistant to the fuel is joined to a stratum of electroplateable polymer disposed to the exterior of the interior stratum . the laminated polymeric structure is then electroplated to form a skin of metal encapsulating the interior polymeric strata . the tank combines the structural design flexibility of plastic with the metal barrier properties regarding evaporative emissions , permitting the use of high contents of oxygenated species in the fuel .
