Abstract: In this paper, the hot-pressing method is selected to prepare piezoelectric vibrator. The effects of different volume ratio of PZT on the dielectric, piezoelectric and mechanical properties of the composites are studied. With the increase of PZT volume fraction in a certain range, the density of the composites, the dielectric constant (ɛ), the dielectric loss (tanδ) and the piezoelectric strain constant (d33) are all increased, while the piezoelectric voltage constant (g33) tends to change smoothly, however, the deformation and compressive yield strength are decreased. The mechanical and piezoelectric properties of the composites are improved after the addition of conductive carbon black particles. The results show that the conductive carbon black can make the structure more compacted and improve the conductivity (σ) of PZT/PVDF composites.
