| Abstract: | In this paper, the elastic constant matrix for anisotropic carbon fiber-reinforced (CFR) material is given by the measurement of ultrasonic wave velocities. According to this matrix and the characteristic equation for anisotropic solids, the slowness curves for this material are obtained. The measuring method used in this paper would be a basis for ultrasonic array scanning technique, and may be a method for the evaluation of the CFR material. |
