Abstract
The structure made of aluminum alloy, which was stiffness-reinforced with CFRP bonded adhesively to decrease vibration, was put to practical use. To put CFRP adhesive structure to practical use, it was necessary to obtain the fatigue life. In current standard test methods, there wasn't an suitable test method for the design of this application. Therefor, we had to use the full scale model equivalent to actual structure each time. In this study, we suggested a compact model for the fatigue life estimation of reinforced structure combined with CFRP bonded adhesively. And fatigue tests using full scale models and compact models were carried out. As the result, we obtained the good interrelation between the fatigue life of the full scale model and the life of the compact model.
