Manufacturing Demonstration Of Large 1-3 Piezoelectric Ceramic/Polymer CompositePanels Using Ceramic Injection Molding

摘要

The objective of this program was to manufacture a large area 1-3 piezoelectriccomposite transducer array for test and evaluation using the Materials Systems Inc. ceramics injection molding technology. A ceramics injection molding process and tooling for fabricating net shape 1-3 composite lead zirconate titanate (PZT) preforms was developed (Ref. 1). In this program, the PZT ceramic preform manufacturing process was scaled up and fabrication processes for 1-3 PZT-polymer composites and transducers were established and optimized. More than 1400 PZT preforms, such as that shown in Figure 1, were produced with a high overall process yield. (MM).
