Performance Analysis of the 1-3 Piezoelectric Composites and Transducer Fabrication

Abstract:

1-3 polymer-based piezoelectric composites were fabricated using epoxy as the matrix by the cut-filling method. The influences of PMN volume fraction on the piezoelectric and dielectric properties of the composite were analyzed, and then the piezoelectric composite was fabricated to transducer whose properties were also analyzed. The results indicate that with increasing the PMN volume fraction, both the hydrostatic piezoelectric voltage g_h and hydrostatic figures of merit d_h·g_h of the composite decrease, while the relative dielectric constant ε_r increases. The hydrostatic piezoelectric strain d_h has the optimum value in the PMN volume fraction range of 40%-60%. The resonant frequency of transducer in water is 306.5 kHz and anti-resonant frequency is 352.6 kHz.
