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.
