| Outline of Final Research Achievements |
In order to clearly understand effects of particle mixture-state on transmitting properties of ultrasonic wave for composite materials, we used “model samples” which simplify various parts of the composite materials and could vary freely some parameters, such as volume ratio, the number of interface, array order. As a result, the transmitting wave of the sample attenuated by both transmission and diffraction at the interfaces. Furthermore, the result implied that diffraction attenuation would be dominant than that of transmission when we measured it for an actual composite materials. Hence, it might be possible to evaluate 3 dimensional mixture-state of the composite material using the diffraction attenuation.
