摘要
复合材料导电性差,一旦遭受雷击,便会产生严重的损伤。随着复合材料在飞机上的用量越来越大,如何对复合材料进行雷电防护,保证飞机遭遇雷击后能够继续安全飞行,成为飞机设计中的一个难点。文中首先分析了复合材料在雷击时的损伤机理,之后介绍了近几年来新型的复合材料雷电防护方法,并结合上述方法,为新型飞机复合材料雷电防护提出了建议。
The conductivity of composite is not good,o nce struck by lightning,it will cause serious damage.With the increasing use of composite in aircraft,how to protect composite from lightning and ensure that the aircraft can continue to fly safely after being struck by lightning has become a difficult problem in aircraft design.In this paper,the damage mechanism of composite under lightning strike is analyzed firstly,and then the new lightning protection methods of composite in recent years are introduced.Combined with the above methods,some suggestions are put forward for lightning protection of new composite aircraft.
