Abstract: A 2-2 type cement based piezoelectric composite was fabricated by dice-and-fill technique.
The effects of the composite thickness on and electromechanical properties of the composite were analyzed. The results show that both the thickness electromechanical coupling coefficient Kt and the mechanical quality factor Qm exhibit the trend of decrease with the increasing of the thickness. With the increase of the thickness, the acoustic impedance of the composite changes little, which fluctuates between 16 and 17 M rayl.
