Dynamic Properties of Fine-Scale 1-3 PZT/Epoxy Piezoelectric Composites


Article Preview

Fine-scale 1-3 PZT/epoxy piezoelectric composites were prepared by a dice-fill process, and their resonance characteristics and dynamic piezoelectric properties were investigated. The resonance characteristic was deeply influenced by PZT volume fraction and the thickness of 1-3 PZT/epoxy composite. The experiments proved that reducing the distance between PZT rods and/or increasing the height/width ratio could weaken the additional coupling effect of lateral resonance mode on thickness mode. The PZT/epoxy composites displayed only thickness-mode resonance when the distance between PZT rods was reduced to 220μm and its aspect ratio was increased up to 10.
