Advanced composite materials are extensively used in aerospace structures due to their high stiffness and strength to weight ratio. Damage progression in the advanced composite materials, however, is very complicated in comparison with conventional metal materials, so it is necessary to characterize the damage tolerance of aerospace composite structures. Pursuing development of lightweight, highly-reliable aerospace composite structures, we are conducting researches on mechanical properties and fatigue characteristics, failure mechanisms, interlaminar delamination propagation behavior, low-cost manufacturing technique, and nondestructive evaluation of advanced composite materials. Furthermore, we have been studying development and evaluation of composites with nano materials, evaluation method for interfacial properties of composites, failure strength of mechanical joint in composite laminates, mechanical properties of composites with irregularly cross-sectional shaped reinforcements, repair of composite sandwich panels, and probabilistic design analysis method for composite structures.
