摘　　要：为增加防雷击复合材料表面膜韧性,本文采用双羟基聚苯醚增韧环氧树脂制备了一种高韧性防雷击复合材料表面膜,通过简支梁冲击试验机、电子拉力试验机和扫描电镜等对表面膜树脂固化物的力学性能和微观结构进行表征,通过模拟雷电流注入试验对铺贴该防雷击表面膜的复合材料层压板进行了雷击测试。结果表明,双羟基聚苯醚用量为10份时,表面膜树脂固化物缺口冲击强度为17.5kJ/m^(2),韧性提高73.3%。模拟雷击测试结果表明防雷击表面膜能有效降低雷电流对复合材料的雷击损伤。In order to increase the toughness of the lightning strike protection composite surface film,the high toughness lightning strike protection composite surface film is prepared by toughening epoxy resin with bis-hydroxy terminated polyphenylene oxide(MPPO).The mechanical properties and microstructure of the surface film cured resin are characterized by simple beam impact testing machine,electronic tensile testing machine and scanning electron microscope.The composite laminate laid on the lightning strike protection composite surface film were tested by the lightning injection test simulated.The results show that when the MPPO is 10phr,the impact strength of the surface film resin cured is 17.5kJ/m^(2),and the toughness increases by 73.3%.The lightning injection test simulated results show that the lightning protection surface film can effectively reduce the lightning damage to the composite material.
