提出了利用超导量子干涉器件（SQUID）梯度仪检测导电复合材料中复杂缺陷的损伤面积和损伤程度的电流检测方法。将该方法应用于不同损伤条件下的碳纤维增强碳基复合材料（C/Cs）试样，验证了该方法的有效性。成功地检测出了与损伤条件相对应的试件中因损伤而产生的弯道电流的面积和数量。讨论了损伤状态分类方法的可行性。
Current detection method was developed to detect damaged area and damage degree of complex defect in electrically conductive composite materials by using superconducting quantum interference device (SQUID) gradiometer. The method was applied to a carbon fiber-reinforced carbon matrix composites (C/Cs) specimen in various damage conditions to investigate the effectiveness of the method. The area and amount of detoured current due to damage in the specimen were successfully detected corresponding to the damage condition. The possibility of the method for classification of the damage condition was discussed.
