摘要/Abstract

摘要： 采用实验方法研究了编织碳纤维/环氧树脂复合材料层合板在干燥环境下受到不同强度等级模拟雷电冲击后的电击破坏特性,并进行了系统分析与机理解释。研究显示,雷电冲击对复合材料造成了三种典型破坏形式,并随着电击强度的增加及铺层角度的改变呈现出不同形态的变化。微观扫描分析发现,电击会对树脂与纤维界面造成严重破坏。

Abstract: This paper experimentally investigates the damage characteristics of two stacking sequenced carbon woven fabric/epoxy laminates subjected to three different levels of simulated lightning strike. The mechanical properties of post-lightning specimens are then studied. Observations show that three types of lightning strike damage have been formed. With the increase of strike intensity, different behaviors have been shown for these three damage forms. Meanwhile, stacking sequence has significant influence on the area of internal delamination. SEM shows that the resin/fiber interfacial bonding is severely damaged by a thermal-mechanical effect due to lightning strike infliction. For both of the two stacking sequenced specimens, the residual modulus and strength decrease with the increase number of lightning strike. However, failure mechanics are quite different for the two kinds.
