碳纤维增强塑料(CFRP)是轻量化领域的理想选择，CFRP的多功能化，特别是通过增加传感器功能，是实现结构健康监测(SHM)中轻量级无电池设备的一种有前途的途径。在本研究中，我们制备了Fe-Co纤维混杂碳纤维复合材料，并对其磁致伸缩响应特性进行了评价。结果表明，CFRP的测量磁通密度随循环弯曲载荷的变化而变化。研究还表明，我们的Fe-Co纤维嵌入碳纤维具有损伤自感知能力。此外，设计的优化和更多的实验和数值研究似乎提高了以Fe-Co纤维为传感复合材料的混杂CFRP的性能。
Carbon fiber reinforced plastic (CFRP) is an excellent choice in the areas where weight reduction is important and multi-functionalization of CFRP, especially by adding sensor capabilities, is a promising approach to realize lightweight battery-free devices in structural health monitoring (SHM). In this study, we fabricated hybrid CFRP with Fe-Co fibers and evaluated the inverse magnetostrictive response characteristics. It was shown that the measured magnetic flux density of the CFRP fluctuates in response to cyclic bending load. It was also revealed that our Fe-Co fiber inserted CFRP has damage self-sensing ability. In addition, it seems that the optimization of design and more experimental and numerical investigation improves the capability of the hybrid CFRP with Fe-Co fiber as sensor composite materials.
