采用水热法制备了一种新型的金属芯压电纤维。金属芯的插入是重要的，因为可以克服陶瓷的易碎性，并且在用作传感器和致动器时不需要电极。并将这些压电纤维安装在CFRP复合材料表面，设计了新型智能板。结果表明，这些复杂的纤维功能的传感器和驱动器的CFRP板。为了评估传感器和执行器。然而，通过水热法，可以在钛丝表面均匀地形成厚度约20μm的压电层，PZT包层的厚度对于致动器的使用来说不足。在本文中，我们解决这个问题，采用挤压方法。采用挤压法研制出了金属芯较厚的PZT包层光纤。将31根压电纤维埋入CFRP复合材料中，对传感器和驱动器的性能进行了测试。我们证明了使用这种智能板可以实现自我感知。
We produced a new piezoelectric fiber with metal core by the hydrothermal method. The insertion of metal core was significant in view that the fragility of ceramics can be overcome and electrodes are not required in the use as sensors and actuators. And new smart board was designed by mounting these piezoelectric fibers on the surface of the CFRP composite. It was shown that these complex fibers function as sensor and actuator in the CFRP board. In order to evaluate the sensor and actuator. However, by the hydrothermal method, piezoelectric layer can be uniformly formed with about 20μm thickness on the titanium wire surface, the PZT clad is insufficient in thickness for the actuator use. In this paper, we solve this problem using extrusion method. We developed the metal core further thicker PZT clad fiber by the extrusion method. 31 piezoelectric fibers were embedded under CFRP composite materials, and the sensor and the actuator function were evaluated. We showed that self sensing was possible using this smart board.
