Passive Vibration Damping Materials: Piezoelectric Ceramics Composites for Vibration Damping Applications
Abstract
For application of the shunted passive piezoelectric damping of structural composites, piezoelectric ceramic fibers (PZT and its family) of several tens of micron diameter were made using sol-gel spinning process. Both acetate and acetylacetonate processes were examined as lead sources. Using the properly chosen spinneret and fiber drawing apparatus, PZT and modified PZT fibers of 10 to l00 micrometers diameter have been successfully produced. Different heat treatments gave different microstructure. Modeling analysis was also performed to estimate achievable damping levels for the composites. The results indicates high damping potential for shunted piezoelectric passive damping composites.... Shunted passive piezoelectric damping, PZT sol-gel fiber.
