<p>A pressure vessel liner (20) for fuel tanks used to store high pressure gasses including methane or compressed natural gas includes thermoplastic materials exhibiting low permeability and mechanical properties resistant to thermal and pressurization strains over the operating cycle of the fuel tanks. The pressure vessel liner (20) is made from a material selected from the group consisting of modified nylon (6) or nylon (11). The present invention also discloses a method of forming a reinforced composite fuel tank wherein the pressure vessel liner (20) is overwrapped with both low-angle helical and high-angle helical filament windings. The high-angle helical windings are overwrapped around the liner across at least the cylinder-to-dome transition region at angles between 60 and 88° with respect to the longitudinal axis of the liner (20).</p> |
