Summary:Lead Zirconate Titanate, PZT, layered into a composite with different materials, produces pre-stressed, curved, devices capable of enhanced displacement. This study focuses on Thunder and Lipca which are built using different combinations of constituent materials. Thunder devices consist of layers of aluminum, PZT, and stainless steel bonded with a hot-melt adhesive. Lipca devices consist of carbon and fiberglass layers with a PZT layer sandwiched in between them. Measuring out-of-plane displacement under load as a function of temperature is used to evaluate field-dependent stiffness. Results show that Lipca devices have higher stiffness than Thunder at 24°C, but lower at other temperatures.
