摘　　要：新型飞机均大量使用纤维增强树脂基复合材料(FRP)作为结构用材,若缺乏足够的保护措施,在遭受雷击之后,这些FRP结构往往会出现比传统飞机相应金属结构更为显著的损伤和破坏,因此,新型飞机FRP结构的雷击防护是一个对航空运行安全具有重大影响的关键问题。综述了国内外关于雷击产生的热/电/磁单一场或复合耦合场对飞机FRP结构造成的损伤问题的研究进展,探讨了雷击时飞机FRP结构中直接损伤和间接损伤的形成机理,分析了飞机FRP结构雷击损伤程度的影响因素。此外,还对当前飞机雷击防护领域常用的雷击防护措施以及飞机FRP结构雷击防护能力的鉴定试验进行了介绍,展望了飞机FRP结构雷击防护领域的研究重点和难点。Fiber reinforced polymer （FRP） is a kind of structural composite commonly and intensively applied in modern aircraft. However, FRP structures often suffer more serious damages and detriments than that of the corre- sponding metallic structures in the traditional aircraft when stroke by lightning. So, lightning strike protection （LSP） of FRP structures in modern aircraft is one of the key problems which have major impacts on the aviation safety. The damage issues of the FRP structures caused by the single thermal/electric/magnetic field or the multiple coupling fields in the lightning strike are reviewed. The formation mechanism of direct and indirect damages of the FRP structures in the lightning strike are discussed, and the factors affecting the degree of lightning strike damage of the FRP structures are also analysed. In addition, the research methods in the field of LSP, commonly used LSP measures and the evalua- tion tests of LSP of the FRP structures are introduced. The research emphasis and difficulty in the field of LSP of the FRP structures are presented as well.
