模拟雷电流作用下单向碳纤维/环氧树脂预浸料的电阻特性
|
Abstract:
为探究碳纤维/环氧树脂预浸料在雷电流作用下的电阻特性，采用10/350 μs波形的低峰值模拟雷电流对单向碳纤维/环氧树脂预浸料进行模拟雷击试验，并采用四电极法测量试验前后碳纤维/环氧树脂预浸料的直流（DC）电阻，利用SEM和拉曼光谱对雷击前后碳纤维/环氧树脂预浸料微观形态、物相结构进行表征，系统研究了受雷击后单向碳纤维/环氧树脂预浸料的DC电阻变化的原因。结果表明：单向碳纤维/环氧树脂预浸料DC电阻不随雷电流峰值的增加单调变化，而是呈先减小后增大的趋势，这是碳纤维石墨化、环氧树脂绝缘性能劣化、碳纤维断裂、隧道效应等因素综合作用的结果。 In order to investigate the resistance characteristics of unidirectional carbon fiber/epoxy prepreg subjected to lightning currents, low simulated lightning currents of 10/350 μs waveform were applied on the unidirectional carbon fiber/epoxy prepreg. The direct current (DC) resistance data of the unidirectional carbon fiber/epoxy prepreg before and after the tests were measured adopting the four-probe method. The SEM and Raman spectrum were used to characterize the morphology and phase structure of carbon fiber/epoxy prepreg before and after the test. The causes of the DC resistance change were analyzed. The results show that the DC resistance of the carbon fiber/epoxy prepreg does not change monotonously with the increase of lightning current, but tends to decrease first and then increase. This trend is the combined effects of graphitization, epoxy insulation deterioration, fiber fracture and tunnel effect. 国家重点研发计划项目（2017YFC1501506
