Claim 15:
16. A method of manufacturing a high-pressure composite pressure vessel configured to contain a gas and/or liquid, the method comprising the steps of:
providing an expandable core vessel;
providing an aligned discontinuous fiber composite material, the aligned discontinuous fiber composite material comprising fibers that are at least 5 mm in length to 100 mm in length or less, wherein the fibers are aligned in a prepreg tape;
wrapping the expandable core vessel with an aligned discontinuous fiber-reinforced composite;
wrapping the expandable core vessel with continuous fiber-reinforced composite;, pressurizing the expandable core vessel, wherein the expandable core vessel is configured to expand applying pressure to the aligned discontinuous fiber-reinforced composite and the continuous fiber-reinforced composite;
heating the expandable core vessel and consolidating the composite overwrap; and
cooling the expandable core vessel under pressure resulting in the high-pressure composite pressure vessel.
