摘　　要：综述了利用炭纤维树脂基复合材料(简称CFRP)自身的导电性,采用直流或交流电阻法在线监测CFRP复合材料在各种单一、循环载荷条件下的电阻变化,将电阻信号与材料微观结构的变化联系起来,从而对CFRP复合材料进行结构健康监控,使电阻法成为一种本征智能化自诊断技术。The changes in electrical resistance of carbon fiber reinforced polymer (CFRP) composites, which are conductive, was described in real time monitored by d.c and a.c electrical resistance measurement under different mono, cyclic loading conditions. The changes in electrical resistance of CFRP composites are related to the changes in the microstructure in the materials. It is expected to monitoring CFRP structure health and make electrical resistance method be an intrinsically intelligent self-diagnosing technique.
