Piezocomposites with 1-3 connectivity were prepared with an epoxy matrix with various fiber volume fractions (V-f). The dielectric constant of the piezocomposites were found to increase from 67 to 190 with the addition of CuO into KNN and increasing Vf in the 1-3 piezocomposite. A fully recoverable electrostrain of 0.023% for the piezocomposites with V-f = 0.63 under an electric field of 4 kV/mm. A very high electrostrictive Q(33) coefficient of 162x10(-3) m(4)/C-2 was obtained from piezocomposites.eninfo:eu-repo/semantics/closedAccessLead-freepiezoelectricpotassium sodium niobatefiberpiezocompositeArticle4201610.1080/00150193.2011.5947552-s2.0-84855773189Q4WOS:000298542700002Q4
