초록

본 논문에서는 분말사출성형공정 (PIM)을 이용하여 1-3형 압전복합체용 PZT 프리폼 (preform)의 제조에 대한 연구를 수행하였다. PZT 분말을 이용해 제조한 피드스탁 (feedstock)의 점도 및 PVT 특성을 측정하였다. 또한 상용 프로그램인 3D-Timon 프로그램을 이용하여 PIM 제조공정 중 사출 성형체의 충진패턴 온도, 압력분포 및 성형 결함 등을 분석하고, 금형 시스템 및 제조공정을 최적화하였다. 최적화된 PIM 제조공정 조건을 사용하여 PZT rod가 균일하게 분포된 1-3형 압전복합체용 PZT 프리폼을 제조할 수 있었다.

In this paper, a fabrication process for PZT preform of 1-3 type piezo-composite were studied using powder injection molding (PIM). The viscosity and the Pressure-Volume-Temperature (PVT) characteristics of the fabricated PZT feedstock were analyzed. The filling patterns, pressure, temperature distributions, and forming defects of the preform were analyzed with 3D TIMON commercial packages during PIM process. Also the fabrication conditions and the delivery system of the preform were optimized during the entire PIM process. Based on the simulated results, the preform having uniform distributions of the PZT rod was fabricated with the PIM process.
