Outline of Final Research Achievements |
The purpose of the study is to develop a design and estimation method for hydrogen storage vessels with Fiber Reinforced Plastics (FRP). The scale of FRP can be classified into micro, meso, and macro structures, and the numerical analytical method in each structure had been developed. In micro structures, flow behaviors of fiber and resin were evaluated with the moving particle method, and the failure envelope was estimated with considering the randomness of fiber arrangement. In meso structures, mechanical characteristics and vibration damping behaviors for woven composites were estimated with the mesh superposition method. In this method, the numerical models were separated into fiber and resin parts, and can estimate the behaviors of each part by one operation. In macro structures, the numerical models of hydrogen storage vessels were generated and the structural analysis was carried out. As the results, the effects of shape of components on CFRP layer can be estimated.
