J. Manuf. Sci. Eng 137(2), 021002 (Apr 01, 2015) (8 pages) Paper No: MANU-13-1376; doi: 10.1115/1.4029092 History: Received October 16, 2013; Revised November 08, 2014; Online December 12, 2014

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.
