摘要

在复合材料领域,许多报告显示,雷击会对结构造成灾难性破坏。本研究为镍涂层玻璃/环氧泡沫芯复合材料的雷击防护提出了新的设计理念。玻璃纤维没有使用纯金属网,而是通过电镀技术用镍颗粒对其进行改性,以提高其导热性和导电性。此外,还在结构中间插入了一块薄英钢板,并引入了泡沫芯材,以减少对结构的损坏。本研究采用了三种不同材料和堆叠顺序的模型。此外,还进行了数值预测,以确定结构的损坏机制。除了热通量源之外,还单独研究了一种称为冲击波超压的机械源,作为电介质材料的一个新因素。这两种雷电源被确定为结构损坏的次要原因。本研究对失效模式进行了分析,以进一步讨论失效机制。

Damage of Nickel-coated glass/epoxy foam-core composites induced by artificial lightning strikes
In the field of composite materials, many reports have shown that catastrophic structural damage is caused by lightning strikes. In this study, new design concepts were proposed for the lightning-strike protection of nickel-coated glass/epoxy foam-core composites. Instead of using a neat metal mesh, glass fibers were modified with nickel particles via a plating technique to improve their thermal and electrical conductivities. In addition, a thin Invar plate was inserted at the middle of the structure and a foam core was introduced to reduce damage to the structure. Three models with different materials and stacking sequences were used in this study. Severe damage was experimentally observed following artificial lightning at a peak current of approximately 150 kA when considering a waveform A. Furthermore, numerical prediction was performed to identify the damage mechanisms of the structures. Besides the heat flux source, a mechanical source known as the shock wave overpressure was investigated separately as a new factor for dielectric materials. These two sources of lightning were determined as minor reasons for the structural damage. The failure modes were analyzed for further discussion about the failure mechanism in this study.
