摘要：

为探究金属网几何结构参数对雷击防护能力的影响，本文建立了含有不同几何结构参数的金属网防护层碳

纤维增强复合材料（CFRP，carbon fiber reinforced polymer）层合板有限元模型，采用热电耦合分析模拟了无

防护、铝网防护和铜网防护下的 CFRP 雷击烧蚀损伤，对比分析了不同几何结构参数铜网防护下的CFRP 烧

蚀损伤。研究发现：在相同几何结构参数下，铜网相比铝网具有更好的雷击防护效果；金属网几何结构参数

能够影响其雷击防护效果，长短节距会影响金属网格节点数量，金属网的雷击防护能力会随着节点数量增

加而提高；增加网线宽度和厚度均能提高金属网的雷击防护能力，增加网线厚度提高的雷击防护能力优于

增加网线宽度；通过对比不同网格内角的铜网防护能力发现，能够相对较好地提高金属网雷击防护能力的

内角角度为 48°。

Abstract:

To explore the influence of the geometric structure parameters of the metal mesh on its lightning protection ability, a

finite element model of carbon fiber reinforced composite (CFRP) laminates with different geometric structure parameters of the metal mesh protective layer was established. The thermal and electrical coupling analysis was used to

simulate the CFRP lightning ablation damage without protection, with aluminum mesh protection and with copper

mesh protection. CFRP ablation damage under copper mesh protection with different geometric structural parameters are compared and analysed. It is found that under the same geometric structure parameters, copper mesh has

better lightning protection effect than aluminum mesh. The geometric structure parameters of the metal mesh can

affect its lightning protection effect. The long and short intercept will affect the number of nodes of the metal mesh.

The lightning protection ability of the metal mesh will increase with the number of nodes. Increasing the width and

thickness of the wire can improve the lightning protection ability of the metal mesh, and the lightning protection ability improved by increasing the wire thickness is better than that by increasing the wire width. By comparing the

protective capability of copper mesh with different grid internal angles, it is found that 48° is the internal angle that

can relatively improve the lightning protection capability of metal mesh.
