Outline of Final Research Achievements

In this study, harmonic generation behavior due to nonlinearity of fiber-matrix interface in composite material was numerically investigated. The results shows that the directivity characteristics of the scattered wave of the second harmonics varies depending on the contact surface rigidity which is an index of the bonding state of the fiber-matrix interface. In addition, we investigated the relationship between microscopic / macroscopic damage and change of harmonic generation characteristics in carbon fiber reinforced plastic (CFRP). In this study, we obtained knowledge on the relationship between the nonlinear parameter β and the damage occurring in the CFRP, and showed the possibility of evaluating damage in CFRP by the attenuation coefficient and harmonic generation characteristics.
