Abstract

In this work, a parametric study is carried out on carbon fiber-reinforced plastic (CFRP) materials to investigate how the spatially varying fiber distribution influences the measured signal in an eddy current testing (ECT) configuration. The measurement setup was modeled using finite element method, while the fiber distribution is taken into account by an inhomogeneous anisotropic conductivity tensor. The study revealed a trade-off relation between the size of the ECT coil and the maximal dynamic range of the ECT signal, which contributes to the understanding of the connection between the fiber arrangement and the ECT signal and provides an opportunity for optimal ECT coil design.

碳纤维增强塑料材料涡流测试的灵敏度分析

本研究对碳纤维增强塑料（CFRP）材料进行了参数研究，以探讨在涡流测试（ECT）配置中，空间变化的纤维分布如何影响测量信号。测量装置采用有限元法建模，而纤维分布则通过非均质各向异性传导张量加以考虑。研究揭示了 ECT 线圈尺寸与 ECT 信号最大动态范围之间的权衡关系，有助于理解纤维排列与 ECT 信号之间的联系，并为优化 ECT 线圈设计提供了机会。
