    • Systems and methods for inspecting electrical conductivity in composite materials having conductive structures are disclosed. In one embodiment, a method for inspecting a conductive structure in a composite bonding region comprises positioning an apparatus operable to induce a current on the conductive structure. The apparatus is positioned on the conductive structure at a first selected position proximate to the bonding region. The method also comprises energizing the apparatus to provide a desired induced current in the conductive structure. The method further comprises detecting an impedance property value of the apparatus. Accordingly, the method additionally comprises positioning the apparatus at a second selected position if the impedance value is within a predetermined range of values. Alternatively, if the impedance value is not within the predetermined range, the method additionally comprises documenting the first selected position.
    • 公开了用于检查具有导电结构的复合材料中的电导率的系统和方法。 在一个实施例中,用于检查复合结合区域中的导电结构的方法包括定位可操作以在导电结构上感应电流的装置。 该装置位于靠近接合区的第一选定位置处的导电结构上。 该方法还包括激励该装置以在导电结构中提供期望的感应电流。 该方法还包括检测该装置的阻抗特性值。 因此,该方法还包括如果阻抗值在预定值范围内,则将装置定位在第二选定位置。 或者,如果阻抗值不在预定范围内,则该方法还包括记录第一选定位置。
