Actuator Capabilities of Piezoelectric Devices Embedded in Composite Laminate

Abstract:

In this work the actuator performance of a ceramic piezoelectric device is studied. Its ability of deforming a Carbon Fiber Reinforced Plastic (CFRP) laminate is measured in the absence/presence of mechanical constraints. Deformation and bending of the CFRP laminate is obtained when a voltage is applied to the piezoelectric device. This deformation was assessed using ESPI technique and a very good agreement with the expected values for the unconstrained case was observed. When completely embedded a reduction of 86% in the piezoelectric response is expected. Finite Element Analysis confirmed the obtained experimental data and a very good linearity in the response was observed.
