Abstract
We have developed a methodology in a framework of meso-scale model for a precise strength evaluation of filament wound carbon fiber reinforced pressure vessel. The vessel is an indispensable component as hydrogen storage tank for fuel cell vehicle itself and hydrogen filling station. A rational strength estimation is expected by means of the meso-scale model with elemental material property obtained by simple material tests concerning resin and fiber bundle. We demonstrate potential ability of meso-scale strength evaluation in problem of local stress enhancement in bundle cross region of helical filament winding.
