摘要

提高碳纤维增强聚合物（CFRP）复合材料的导电性，而不显著影响重量或降低机械性能，在航空航天领域的雷击防护和电磁干扰屏蔽方面具有巨大的潜力。在此，我们提出了一种利用软导电纱进行全厚度拼接的创新方法。对复合材料的综合性能进行了系统评价，结果表明，使用软导电纱可使复合材料的通厚导电性和层间断裂韧性分别提高72倍和7.5倍，而对拉伸性能的影响最小。研究结果表明，软导电纱的全厚拼接为开发多功能结构复合材料提供了新的思路。

Multifunctional stitching of carbon fibre reinforced composites with soft conductive yarns for enhancing electrical conductivity and mechanical properties

Enhancing the electrical conductivity of carbon-fibre reinforced polymer (CFRP) composites without significant impact to weight or degradation of mechanical properties has great potential for lightning strike protection and electromagnetic interference shielding in aerospace applications. Herein, we present an innovative method of through-thickness stitching with soft conductive yarns. A systematic evaluation of the multifunctional performance of the stitched composites reveal that the use of soft conductive yarns can greatly enhance the through-thickness conductivity and interlaminar fracture toughness by 72 folds and 7.5 folds respectively, with a minimal impact on tensile properties. The findings suggest that through-thickness stitching with soft conductive yarns offers a new strategy for developing multifunctional structural composites.
