Demonstration of Manufacturing Process for Large Area, Multilayer PiezoelectricComposites

摘要

FMI is conducting a program to demonstrate the capability of economical automatedfabrication of fiber reinforced 1-3 piezoelectric composite materials. A series of test specimens is being fabricated and tested to establish relationships between composite structure and performance. The results will be used to design panels in a 30.5 x 30.5 cm (12 inches x 12 inches) multilayer structure. A modeling study at Stanford University is also being supported by specimen fabrication and testing at FMI. Four specimens from the basic set have been completed and twenty-four more are in production. Eighteen specimens have also been prepared for the Standard task. Further development has occurred in processing methods including a study of resin systems, development of poling procedures and establishment of quality control standards for PZT rods.
