Abstract
A method of manufacturing a high-pressure composite pressure vessel for high-pressure being at or above 70 bar (1000 PSI or 7 MPa) includes providing an expandable core vessel defining a hoop section between end domes. An aligned discontinuous fiber composite material is wrapped over the expandable core vessel aligning with a plurality of load paths present in the expandable core vessel being over the hoop section and end domes. The aligned discontinuous fiber composite material has fibers in a prepreg tape that are at least 5 mm in length to 100 mm in length or less. Next, a continuous fiber-reinforced composite is wrapped over the aligned discontinuous fiber-reinforced composite along the hoop section and not wrapped along the end domes. The expandable core vessel may be pressurized and heated to consolidate the composite overwrap. Finally, the vessel is cooled under pressure resulting in the high-pressure composite pressure vessel.
