Abstract: Zinc and niobium modified lead zirconate titanate (PZN-PZT) fibers were prepared by the sol-gel method. After sintering at various temperatures the crystal structure of the ceramic fibers was determined by X-ray diffraction. The morphology of the ceramic fibers was studied using a scanning electron microscope. A bundle of ceramic fibers of 25 μm diameter was placed in a plastic tube, which was then filled with epoxy. After curing, a PZN-PZT fiber/epoxy 1-3 composite rod was formed. The rod was sliced into disks which were then polished to a thickness of approximately 40 μm. A composite disk with 0.62 ceramic volume fraction was poled under an electric field of 3.5 kV/mm at 120°C for 15 min. The electromechanical coupling coefficient k t, piezoelectric coefficient d33 and relative permittivity ε of the disk were found to be 0.67, 403 pC/N and 1300, respectively. The hysteresis loop of the composite was also determined, and the remnant polarization Pr was found to be 12 μC/cm2.
