Shape control using embedded piezoelectric actuators

Abstract

This paper describes a Carbon Fibre Re-enforced Polymer (CFRP) panel with a number of piezoelectric bimorph actuators embedded in the neutral plane of the CFRP panel. The shape of the composite panel was controlled by applying a voltage across one or more of the embedded bimorph actuators. The displacement of the composite panel was monitored as a function of position and the number of actuators activated using a MTI 2000 Fotonic Sensor.
