Xiaojing Guo, Dongyu Xu, Shifeng Huang

DOI: 10.5185/amlett.2014.1405569

Keywords: 1-3 piezoelectric-damping composites; epoxy resin; damping performance; piezoelectric property.

Abstract: 

1-3 piezoelectric-damping composites were fabricated using piezoelectric ceramic as functional filler and epoxy resin as matrix by cut-filling method. The fabrication procedure of the composites was introduced. The effect of ceramic volume fraction on the damping behavior and the piezoelectric strain factor d33 were studied. The results show that the damping property was firstly improved, and then decreased with the increase of the ceramic volume fraction. An optimal ceramic volume fraction of 15% was shown. TA increased from 29.78 to 32.34. The piezoelectric strain factor d33 reached 323pC·N-1. Copyright © 2014 VBRI press.
