Claims19
A fuel permeation barrier fuel tank comprising:
- a tank shell having a wall formed from a plurality of layers;
- said layers comprising at least an inner layer, an outer layer, a first fuel permeation barrier layer disposed between said inner layer and said outer layer and being made of a polyvinylidene fluoride (PVDF) material, and a second fuel permeation barrier layer disposed between said inner layer and said outer layer and being made of a material different than said first fuel permeation barrier layer.
A fuel permeation barrier fuel tank comprising:
- a tank shell having a wall formed from a plurality of layers;
- said layers comprising at least an inner layer and an outer layer being made of a thermoformable polymer;
- and
- a first fuel permeation barrier layer disposed between said inner layer and said outer layer and being made of a polyvinylidene fluoride (PVDF) material and a second fuel permeation barrier layer disposed between said inner layer and said outer layer and being made of a ethylene vinyl alcohol material.

A fuel tank comprising:
- a tank shell having a wall formed from a plurality of layers;
- said layers comprising at least an inner layer and an outer layer comprising either one of a polyethylene material and polyolefin material;
- and
- a first fuel permeation barrier layer comprising a polyvinylidene fluoride (PVDF) material disposed between said outer layer and said inner layer, wherein said inner, layer and said outer layer have a thickness greater than said first fuel permeation barrier layer, and a second fuel permeation barrier layer disposed between said inner layer and said outer layer and being made of a ethylene vinyl alcohol material.
