22 PZT/Epoxy piezoelectric composite materials with parallel model was prepared by pouring processing,and the performance of composite was investigated.The results indicated that the optimal proportion between epoxy resin and polyamide resin 650 was 4∶1,and was then cured at room temperature for 3~5 days.With the increase of frequency,dielectric loss tanδ decreased and stabilized. The piezoelectric constant d33,dielectric constant ε and dielectric loss tanδ increased with PZT volume content.At 1 kHz maximum piezoelectric constant d33 reached to 146.5 pC/N,dielectric constant ε was 2 100 and dielectric loss tan δwas 0.090.The bending strength of 162.2 MPa and deflection of 6%~10% for PZT/Epoxy composite materials could be achieved respectively when volume fraction of PZT was 63.5%.
