摘要

碳纤维增强聚合物（CFRP）管以其优越的材料性能被应用于大孔径可展开空间天线中。CFRP钢管的冲击损伤会严重影响钢管的承载能力。高效、便捷的CFRP管材冲击损伤无损评价方法是至关重要的。本研究发展了同时考虑CFRP介电性能和各向异性电导率的高频涡流测试（HF ECT）有限元分析方法，并建立了解释CFRP中位移电流和涡流作用机理的纤维束模型，为预测CFRP中高频ECT信号提供指导。研制了一种高信噪比互差筒管探头，专门用于检测CFRP管的冲击损伤。利用力锤冲击损伤构建了高频电刺激实验系统并进行了验证，验证了方法和探头的有效性，成功检测出了不可见的冲击缺陷。

Impact damage detection on carbon fiber reinforced polymer tube by a mutual differential Bobbin probe

Carbon fiber reinforced polymer (CFRP) tube is utilized in large aperture deployable space antennas for its superior material properties. Impact damages on CFRP tube can significantly impair the load-bearing capacity of the tubes. Efficient and convenient non-destructive evaluation method of impact damage in CFRP tubes is essential. This study develops a high-frequency eddy current testing (HF ECT) finite element analysis method that accounts for both the dielectric properties and anisotropic conductivity of CFRP, and establishes a fiber bundle model that explains the operating mechanism of displacement current and eddy currents in CFRP, offering guidance for predicting HF ECT signals in CFRP. A high signal-to-noise ratio mutual differential Bobbin probe is developed specifically for detecting impact damage in CFRP tubes. A HF ECT experiment system is constructed and validated using impact damages induced by a force hammer, demonstrating the effectiveness of method and probe, and the invisible impact defect is detected successfully.
