RESEARCH ON THE PREPARATION AND PROPERTIES OF 2-2 CURVED PIEZOELECTRIC COMPOSITE

摘要：

　　The 2-2 curved piezoelectric composites were prepared with epoxy resin as matrix and curved piezoelectric ceramics as functional phase, and the curved piezoelectric ceramics were prepared by cutting the piezoelectric ceramics ring into different radian along the radial direction uniformly.The effects of the structural parameters on the performances of piezoelectric composites were studied.The height and thickness of piezoelectric ceramic have little influence on the piezoelectric constant and dielectric constant.And with the increase of the piezoelectric ceramic high and thickness, the variation of electromechanical coupling coefficient increases and decreases respectively, and the mechanical quality factor all appears to decrease.With the increase of the composites radian, the d33 and Kt values all firstly increase and then decrease.The dielectric constant increase with the increase of the composites radian, and the mechanical quality factor shows no obvious varying rule.
