INFLUENCE OF THICKNESS ON THE ELECTROMECHANICAL PROPERTIES OF 2-2 CEMENT BASED COMPOSITE
A 2-2 type cement based piezoelectric composite was fabricated by dice-and-fill technique.The effects of thc composite thickness on and electromechanical properties of the compositewere analyzed. The results show that both the thickness electromechanical couplingcoefficient Kt and the mechanical quality factor Qm exhibit the trend of decrease with theincreasing of the thickness. With the increase of the thickness, the acoustic impedance of thecomposite changes little, which fluctuates between 16 and 17 M rayl.
