我们报道了一种新的“净形”加工方法，用于制造超细尺度1-3陶瓷结构。我们使用粘性聚合物加工（VPP），结合改进的“失模”方法获得钛酸铅锆（PZT）鬃毛块，其特征尺寸为12-100 /spl mu/m，长径比为3-10。实验中，我们组装了1-3个压电复合换能器元件，并报告了它们的电阻抗和脉冲回波行为，并证明了与计算机建模的密切相关性。我们得出的结论是，我们开发的加工路线有潜力将压电复合材料的频率范围扩展到超出现有限制的范围。
We report on a new "net-shape" processing method for the fabrication of ultrafine scale 1-3 ceramic structures. We have used viscous polymer processing (VPP), combined with a modified "lost mould" method to obtain lead zirconium titanate (PZT) bristle-blocks with feature sizes of 12-100 /spl mu/m and aspect ratios of the order of 3-10. Experimental, 1-3 piezo-composite transducer elements have been assembled and we report on their electrical impedance and pulse-echo behavior and demonstrate a close correlation with computer modeling. We conclude that the processing route we have developed has the potential to extend upwards the frequency range of piezo-composite material beyond existing limits.
