A simulation system, named FrontCOMP, has been developed for a reasonable strength evaluation of carbon fiber reinforced plastic (CFRP) members. The fiber bundle formed by resin is definitely distinguished for numerical modeling in meso-scale. A finite element data of meso-scale model is automatically constituted by the system, and transferred to residual stress analysis after cure. The ultimate strength of a CFRP member is estimated by explicitly taking account of meso-scopic structural parameters, such as material non-linearity of resin, size of fiber bundle and so on. The validity of the system is exemplified through an analysis of high pressure vessel for adequate design of hydrogen tanks equipped on fuel cell vehicles.
