| Outline of Final Research Achievements |
In order to evaluate the fatigue properties of CFRP laminates in the very high cycle region, i.e. more than 10,000,000 cycles, within a practical period, the feasibility study of an ultrasonic fatigue testing method for CFRP laminates was conducted. The experimental study revealed that it is possible to conduct axial fatigue testing of CFRP laminates by using an open-hole specimen with air cooling and intermittent loading.
