摘要: 目前飞机复合材料结构件雷电防护广泛采用防雷击铜网,然而这导致了整体结构重量增加的问题。为满足雷电防护层减重的迫切需求,本研究针对2A区雷电防护铜网进行轻质化设计。首先,结合2A区传统铜网设计参量,选取了不同厚度、网孔规格和梗宽下的13组铜网试样,通过仿真系统研究了不同参数下带铜网复合材料结构件的雷击损伤特性,确定了严重雷电直击工况下的铜网参数边界。基于此,设计了一款新型轻质铜网,经试验验证,其雷电防护性能满足设计要求,且单位面积重量较当前主流铜网产品降低了14.5%。

Abstract: At present, lightning protection of aircraft composite structural parts widely uses lightning protection copper mesh, however, this leads to the problem of increasing the weight of the overall structure, in order to meet the urgent need for weight reduction of the lightning protection layer, this study is aimed at the lightweight design of lightning protection copper mesh in Zone 2A. Firstly, 13 groups of copper mesh samples with different thicknesses, mesh sizes and strand width were selected in combination with the design parameters of traditional copper mesh in Zone 2A, and the lightning damage characteristics of composite structural parts with copper mesh under different parameters were investigated through the simulation system, and the parameter boundaries of copper mesh under the severe direct lightning strike condition were determined. Based on this, a new type of lightweight copper mesh was designed, and its lightning protection performance was verified to meet the design requirements, and the weight per unit area was reduced by 14.5% compared with the current mainstream copper mesh products.

Key words: carbon fiber composites, direct lightning effect, lightweight copper mesh, electro-thermal coupling, lightning protection effect
