碳纤维增强聚合物基（CFRP）复合材料层板以其耐腐蚀、比强度和模量高、疲劳强度和疲劳损伤容限高、热膨胀系数低、重量轻等优点，越来越多地应用于航空航天领域的结构材料。 CFRP 复合材料层压板的使用日益增多引起了人们对雷击影响的严重关注，因此有必要研究其雷击损坏特性。根据报道的照片和电离波分析，实际雷电弧通道的直径从几厘米到几米不等。深入了解雷击冲击引起的材料损伤特性对于减少复合材料层合板的雷击损伤同时保持力学性能至关重要。已有大量研究调查雷电放电对飞机复合材料结构的影响，但雷电通道直径的影响尚未系统研究。本研究的目的是找出闪电放电中观察到的电弧直径与其对 CFRP 复合材料层压板造成的损坏程度之间的相关性。
Carbon fiber reinforced polymer matrix (CFRP) composite laminates are increasingly used as structural materials in the aerospace industry owing to their various advantages such as the corrosion resistant property, high specific strength and modulus, high fatigue strength and fatigue damage tolerance, low coefficient of thermal expansion, and light weight. Such an increasing use of CFRP composite laminates raises significant concern over lightning strike impact and necessitates the investigation of their lightning strike damage characteristics. The diameter of an actual lightning arc channel varies from several centimeters to several meters according to reported photographs and ionizing wave analysis. A thorough understanding on the material damage characteristics caused by a lightning strike impact is essential for reducing the lightning strike damage of the composite laminates while maintaining the mechanical properties. There have been numerous studies that investigated the effect of lightning discharges on aircraft composite structures, but the impact of the lightning channel diameter has not been systematically investigated. The goal of this research is to find the correlation between the diameter of electric arcs observed in lightning discharges and the level of damage it causes on CFRP composite laminates.
