摘要/Abstract

摘要： 为了探究制造过程中少量碳粉污染对复合材料叶片防雷性能的影响,采用有限元方法建立复合材料静电场模型,并采用高压闪络附着试验方法测试了添加质量分数为0.5wt%的碳粉的环氧树脂,结果显示复合材料蒙皮/PVC芯材区以及纯蒙皮区在高压闪络测试中均不会发生击穿。在试验中观察到多个分布在玻璃钢浅表层的终端为碳粉的细小闪络,数值仿真和试验结果对比分析表明,此现象与仿真结果中碳粉深度小于0.3 mm则可能产生感应闪弧,在更大深度下无法产生感应闪弧的结论吻合。

Abstract: In order to analyze the influence of milled carbon fiber pollution on lightning protection of GFRP, simulation analysis of electrostatic field based on FEM was established. Furthermore, high volt lightning tests were implemented with GFRP sample (0.5wt% milled carbon fiber). The results showed that the GFRP skin/PVC core material area and the pure skin area did not undergo breakdown in the high volt lightning tests. In the experiment, multipleting flashovers of milled carbon fibers were observed at the shallow surface of the fiberglass. The comparative analysis between numerical simulation and experimental results shows that the phenomenon is consistent with the conclusion in the simulation results that induced flashover may occur when the milled carbon fiber depth is less than 0.3 mm, and cannot occur at greater depths.
