Abstract
A simulation integrated material test methodology is proposed for carbon fiber reinforced plastic (CFRP) pressure vessels, that is crucial component both for fuel cell vehicle and hydrogen gas station. An accurate strength evaluation is possible by taking account of local stress concentration caused by meso-scopic structure of fiber-bundle/resin system. High performance computer infrastructure represented by "KEI" has enabled the meso-scale finite element analysis, in which fiber-bundle/resin structure is explicitly handled. We demonstrate the validity of the analysis, focusing an attention on fiber-bundle crossover.
