Abstract

New piezoelectric mechanical dampers have been fabricated using composites of piezoelectric ceramic: polymer: carbon black. Significant vibrational damping was observed in the composites with a ceramic volume fraction more than 50%. Damping characteristics are contlollable by changing the conductivity through the carbon black concentration.
