Abstract :
PZT powder is synthesized by solid reaction and PMN-PT is synthesized by columbite method. PZT and PMN-PT piezoelectric fibers are prepared by sol-powder mixture extrusion. 1-3 piezoelectric fiber composites are fabricated by arraying-casting technique. The influence of fiber composition on dielectric properties and piezoelectric properties are studied. The results show that the values of kt and kt/kp of 1-3 composite are higher than ceramic bulks, the values of Qm, kp, d33 and ¿T of 1-3 composite are lower than ceramic bulks. It is also indicated that the variation law of composite properties is the same as ceramic bulk properties. Both the piezoelectric constant d33 and the rate kt/kp of PMN-PT PFC are higher than that of PZT PFC..
