Laminated fuel tank structure

A fuel tank for a vehicle comprising:

• a first housing part having an outer peripheral flange and a central portion extending between and offset from said flange,
• a second housing part having an outer peripheral flange and a central portion extending between and offset from said flange,
• said flanges on said housing parts adapted to abut against each other so that a chamber is formed between said central portions of said housing parts,
• means for sealingly securing said flanges together,
• wherein the central portion of each housing part is a laminate structure comprising:
• an outer layer of uniform thickness constructed of a material resistant to impact and abrasion,
• a heat and light reflective layer adjacent said outer layer,
• a vapor barrier layer of uniform thickness constructed of a material impervious to hydrocarbon vapors adjacent said heat and light reflective layer, and
• a structural layer adjacent said vapor barrier layer for increasing the strength and rigidity of said fuel tank,
• a chemical resistant inner layer of uniform thickness constructed of a material resistant to erosion from hydrocarbons and conventional fuel additives,
• wherein said vapor barrier layer is sandwiched between said outer layer and said inner layer so that said laminate structure has a uniform thickness, and
• means for bonding said outer layer, said vapor barrier layer and said chemical resistant inner layer together.
