Paper Abstract

This paper details the progress made towards the realization of a robust and user friendly system designed to damp vibration in composite structures. The system relies on polyvinylidene fluoride (PVDF) strain sensors linked to PZT actuators through a simple feedback signal inversion algorithm. The PVDF is coated to reduce charge leakage and the PZT ceramics are encapsulated to provide easy to handle, robust actuators that do not electrically short in CFRP based composites. Details of the system design are presented along with initial results showing vibration control of multimoded CFRP cantilevers.
