Paper Title:
Influence of Base Thickness on Properties of 1-3-2 Connectivity Cement Based Piezoelectric Composite
  Abstract

Sulphoaluminate cement and Lead Niobium-Magnesium Zirconate Titanate ceramic (PMN) were used as matrix and functional component to fabricate 1-3-2 piezoelectric ceramic-cement composites by dicing and filling method. The influences of base thickness on piezoelectric, dielectric and electromechanical coupling properties of the composites were analyzed and discussed. The results show that with increasing the base thickness, the piezoelectric stain factor d33 increases gradually, while the piezoelectric voltage factor g33 decreases. The relative dielectric factor εr decreases initially and then increases, while the dielectric loss tan δ increases initially and then decreases. When base thickness is 0.50 mm, εr has the minimum value of 1406. When base thickness is 3.00 mm, tan δ reaches the minimum value of 0.251. With increasing the base thickness, the planar electromechanical coupling coefficient Kp exhibits the decreasing trend, and the thickness electromechanical coupling coefficient Kt and acoustic impedance Z show the increasing trend.
