Abstract In the present paper, bismaleimide resin (BMI) based carbon fiber reinforced composite (CFRP) with remarkable lightning strike protection (LSP) capability was developed. A light weight conductive veil was prepared and interleaved to CFRP with the through thickness conductivity of 27.9 S/m, while its static mechanical strength was unaffected. We prove that the through thickness conductive pathways made CFRP to disperse the lightning current more effectively; reducing the lightning damage toward the inner part of the CFRP. The deepening Joule heat was proved to be the major reason of the penetrating structure failure. Comparing to the state-of-art metal sacrifice layer for LSP, the through thickness conductive CFRP has lighter weight and similar LSP capability, without compromising the mechanical strength.

用于雷击保护的基于 BMI 的导电结构 CFRP 的开发

摘要 在本文中，开发了具有显着雷击保护（LSP）能力的双马来酰亚胺树脂（BMI）基碳纤维增强复合材料（CFRP）。制备了一种轻质导电膜并将其与 CFRP 交织，其厚度为 27.9 S/m，而其静态机械强度不受影响。我们证明了贯穿厚度的导电通路使CFRP能够更有效地分散雷电流；减少对CFRP内部的雷击伤害。加深焦耳热被证明是穿透结构失效的主要原因。与最先进的 LSP 金属牺牲层相比，全厚度导电 CFRP 具有更轻的重量和类似的 LSP 能力，同时不影响机械强度。
