Influence of the Thermoplastic Type on the Thermal Evolution of a Piezoceramic Patch During the Manufacture of a Smart Thermoplastic Part by Injection Molding Process

摘要

The frame of the paper is the integration of PZT actuators and sensors within thermoplastic mechanical structures. The objective of the work reported here was to select the appropriate thermoplastic materials for the smart thermoplastic manufacturing. In order to reach this objective, a comparative study was realized between different thermoplastic materials taking into consideration the PZT patch maximum temperature, the overheat time of the PZT patch during injection process, and the PZT loss in piezoelectric properties due to its thermal fragility.
