PZT fibrous material has many important applications in sensors, actuators and transducers. In this paper, piezoelectric fibers had been fabricated by carbon template method using lead acetate trihydrate, zirconium nitrate pentahydrate , titanium butoxide as raw materials, and glycol monomethyl ether as the organic solvent. In addition, 1-3 piezoelectric composite had been prepared by arranging PZT fibers and casting epoxy resin. The fiber and its composite samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The results showed that PZT fibers with the diameter of a few microns had been obtained by carbon template method within right ingredient and water. The fibers were straight and sleek, and had the crystal structure of perovskite type after sintered at the temperature of 850°C for 30 min. The piezoelectric fiber composites with order structure had also been made out.
