    摘要： A pressure vessel includes curved sidewalls configured as a frame having a polygonal outline, a planar top side and a planar bottom side attached to the curved sidewalls forming a sealed pressure chamber therebetween. Each planar side includes a contoured surface having shaped pressure resistant features formed thereon. A preferred method for forming the pressure resistant features includes hydraulic pressurization to induce plastic strain. The pressure vessel also includes an array of internal support posts within the sealed pressure chamber attached to the planar sides in a geometrical pattern, such as a hexagonal array. The support posts can be solid metal cylinders, hollow tubes or tubes through which reinforcing materials, such as carbon fiber, glass fiber, or fiber/epoxy tape have been passed. A composite pressure vessel includes tubular internal support posts reinforced with reinforcing materials, as well as contoured surfaces and curved sidewalls reinforced with these same reinforcing materials.

    摘要： A pressure vessel includes a vessel body, a first rib and a second rib. The vessel body includes a first surface and a second surface. The first rib projects in a second direction from the first surface and extends in a first direction. The second rib provided in series with the first rib, projects in the first direction from the second surface, and extends in the second direction. A width in the second direction of the internal space is smaller than a width in the first direction of the internal space. A maximum value of a projection amount of the second rib from the second surface to the outside of the vessel body in the first direction is smaller than the maximum value of a projection amount of the first rib from the first surface to the outside of the vessel body in the second direction.

    摘要： A method of manufacturing a high-pressure fluid vessel includes forming a first portion of a high-pressure fluid vessel with a molding process. The high-pressure fluid vessel includes a stack of capsules. Each capsule includes a first domed end, a second domed end, and a semicylindrical portion extending between and connecting the first domed end to the second domed end. The method further includes forming a second portion of a high-pressure fluid vessel with the molding process. The second portion of the high-pressure fluid vessel is positioned adjacent to the first portion of the high-pressure fluid vessel. The second portion of the high-pressure fluid vessel is welded to the first portion of the high-pressure fluid vessel.

    摘要： A grid stiffened structure which includes a wall which extends in a direction transverse relative to a plane and an elongated rib connected along an elongated dimension of the rib to the wall such that the elongated rib extends along the wall and forms an angle with an axis which extends in a direction perpendicular to the plane. The elongated rib defines a free sidewall which extends from the wall positioned on a first side of the elongated rib and extends in a direction about the elongated rib and transverse to the elongated dimension to the wall positioned on a second side of the elongated rib. The wall and the elongated rib are constructed of a plurality of layers of material which extend in a direction transverse to the axis.
