据报道，传统的碳纤维增强塑料（CFRP）在整个厚度方向上表现出较低的电导率，并且已经为开发新的树脂系统以改善CFRP层压板的整个厚度电导率和功能性铺平了道路。本研究设计并研究了一种新型的聚苯胺/苯酚树脂，它具有高的导电性和机械强度。通过添加高达（~23.30%）苯酚的该PANI/苯酚树脂制造的CFRP产生0.6S/cm的贯穿厚度的电导率，并且分别表现出477 MPa和59.2GPa的弯曲强度和模量值。我们进一步评估的有效性的雷击保护聚苯胺/苯酚基导电CFRP层压板与模拟雷击试验。本质上，这项研究报告了PANI/苯酚基CFRP作为雷电抑制材料的有效性，而无需应用传统的金属基雷击保护（LSP）系统。
Traditional carbon fiber reinforced plastics (CFRPs) have been reported to exhibit lower electrical conductivity in the through-thickness direction, and have since paved the path for developing new resin systems to improve the through-thickness electrical conductivity and functionality of CFRP laminates. This study designs and investigates a novel Polyaniline (PANI)/Phenol resin, which possesses high electrical conductivity and mechanical strength. The CFRP manufactured by this PANI/Phenol resin with an addition of up to (~23.30%) phenol resulted in 0.6 S/cm through-thickness conductivity and demonstrated flexural strength and modulus values of 477 MPa and 59.2 GPa, respectively. We further evaluate the effectiveness of lightning strike protection of PANI/Phenol-based conductive CFRP laminates with a simulated lightning strike test. In essence, this research reports on PANI/Phenol-based CFRP's effectiveness as a material for lightning suppression without applying traditional metal-based lightning strike protection (LSP) systems.
