摘要

涡流检测在导电材料的无损检测中得到了很好的应用。频率范围高达100 MHz的射频(RF)涡流技术的发展，使其有可能扩展到传统的应用领域，甚至是像CFRP这样的低导电性材料。结果表明，射频涡流技术对复合材料的综合诊断提供了越来越多的有价值的信息。CFRP的介电常数和电导率都会影响射频涡流仪测量的复合阻抗。

High resolution radio frequency inspection of carbon fiber composites

Eddy current testing is well established for non-destructive testing of electrical conductive materials. The development of radio frequency (RF) eddy current technology with frequency ranges up to 100 MHz made it possible to extend the classical fields of application even towards less conductive materials like CFRP. It turns out that RF eddy current technology on CFRP generates a growing number of valuable information for comprehensive material diagnostic. Both permittivity and conductivity of CFRP influence the complex impedance measured with RF eddy current devices.
