An optimum design methodology is investigated for FRP pressure vessel of hydrogen gas with plastic liner. The isotensoid design of uniform tensile strain along fiber is a major candidate for the minimum weight optimum design, since the fiber bears internal pressure most efficiently. The isotensoid design is theoretically derived from membrane modeling of FRP layers, neglecting three-dimensional effect. We derived a minimum weight design method taking account of three-dimensional effect exactly. The baseline design is given by the isotensoid design of membrane theory, then the minimum weight design is searched for through iterative calculations of maximum strain analyses along fiber and layer thickness determinations. The random searched technique is included in the solution search to avoid local minimum. The validity of the proposed method is demonstrated in problem of burst proof test.
