Abstract: A pressure vessel for storing fluid is disclosed. The pressure vessel includes a metallic liner comprising a cylindrical portion and a pair of ellipsoidal domes positioned at opposite ends of the cylindrical portion. Further, the pressure vessel includes a composite material wrapped over the cylindrical portion and the pair of ellipsoidal domes. The composite material is formed of a polymeric matrix reinforced with fibers, the composite material comprises of a combination of hoop layers and helical layers which are positioned in predetermined order with respect to each other. A hoop layer is wrapped over a cylindrical portion of the metallic liner of the pressure vessel and a helical layer is wrapped over both the cylindrical portion and the pair of ellipsoidal domes. The helical layer is wrapped on each of the pair of ellipsoidal domes in a manner that a helical angle is defined at an intersection between the cylindrical portion and the pair of ellipsoidal domes.
