Abstract


This work presents the design, development, and characterization of unimorphtype laminated piezoelectric actuators. The actuators consist of a piezoelectric lead zirconate titanate (PZT) layer sandwiched between unidirectional Kevlar 49 and epoxy composite layers. Differential thermal expansion during processing places the ceramic plate in a state of residual compression and results in a curved actuator. Modified classical lamination theory (MCLT) (modified to include piezoelectricity) was used to design the actuators. Three layups were fabricated and characterized: [90/PZT/90/0], [90(2)/PZT/90/0(2)], and [90(3)/PZT/90/0(3)]. Results were compared to a commercially available unimorph-type actuator made from layers of metal, adhesive, and piezoelectric material. The classical lamination theory predictions were in good agreement with the measured response of the PZT composite actuators and provide a useful design tool for these actuators.
