对钛酸铅／环氧树脂复合压电材料的极化性能进行了研究。结果表明，较高的极化电场强度和较高的极化温度均有利于压电复合材料压电性能的提高，但超过一定位时，材料会达到饱和极化状态，压电应变常数趋于稳定。
Polarization properties of lead titanate / epoxy composite piezoelectric materials were studied. The results show that the higher polarization electric field and the higher polarization temperature are conducive to the piezoelectric properties of piezoelectric composites, but beyond a certain position, the material will reach the state of saturated polarization, the piezoelectric strain constant tends to stable.
