Shape memory alloys (SMAs) are widely used a s the sensor, actuator and damping instruments. The hybrid composites that embedded with SMAs show some unique properties or functions such as self strengthening, active modal modification, high damping, damage resistance, control and self healing so they can provide tremendous potential in many engineering applications. Since that vibration control is one of the most important and common applications of the shape memory alloys, the study of vibration characteristic of SMAs become important. Past researcher like Jae-Sang Park et al. 111 had studied on the vibration of thermally post-buckled composite plates embedded with shape memory alloy fibers. Although the shape memory alloys had been manufactured and used in the modem smart structure, but the major internal problem of shape memory alloy still occur as a result of the characteristic of shape memory effect only limited to motion along the fibers' longitudinal axes [2]. The inter-relationship between the angle of SMAs embedded into the composite and the effect of different angle of SMAs embedded into the composite to the vibration characteristic had not been studied and determined by previous researchers. In this paper, there were four specimens with different angle orientation of the arrangement of SMAs in the composite to be fabricated. These four specimens are the composite plate that without SMAs was fabricated as a reference for analysis, and for the sample which embedded with Muscle Wire type Flexin01375 HT were oriented at o', 45' and 90' to the epoxy/fiber glass reinforcement composite plate. The specimens were tested for the boundary conditions of clamped-free. The amplitude of the wave form received from the vibrometer for the composite plate was studied.
