Passive Vibration Damping Materials: Piezoelectric Ceramic Composites for Vibration Damping Applications

Abstract

The study to produce ultra-fine (less than 50 micrometers in diameter) lead zirconate titanate (PZT) ceramic fibers for passive damping application has been carried out under several aspects. Sol-gel chemistry was undertaken to produce stable spinnable sol, as well as high quality PZT fibers. Due to the extreme geometry of such fibers, special characterization and poling methods were established. Single fiber dielectric properties, polarization hysteresis, and mechanical properties have been measured. Several methods for applying optimum resistive coatings were also explored. The analytical model of passively damped polymer composites using resistively shunted piezoelectric fiber was further developed to predict the behavior of such composites.
