摘要/Abstract

摘要： 研究了两种典型铺层([45₂/0₂/-45₂/90₂]s、[30₂/0₂/-30₂/90₂]s)编织型碳纤维复合材料试样件在受到不同湿热环境(23 ℃、60 ℃)作用下的雷电冲击破坏特性。同时,对两种铺层的标准试样件在60 ℃湿热环境浸泡条件下受雷电冲击后的特性进行了微观机理分析。结果显示,湿热效应会改变材料的导电特性并且显著增大雷电破坏区域的面积,但铺层角度对破坏形态的影响则趋于不明显。微观扫描结果显示,纤维与树脂间粘结强度在湿热作用下显著降低并在雷电冲击下严重破坏,出现层间与层内的分层开裂现象。

Abstract: In this paper, damage characteristics of two typical ply ([45₂/0₂/-45₂/90₂]s、[30₂/0₂/-30₂/90₂]s) woven carbon fiber composite material samples, which are subjected to different hygrothermal environments (23 ℃ and 60 ℃), were studied. At the same time, the microscopic mechanism characteristics of two kinds of standard sample member ply by lightning strike at 60 ℃ after a hygrothermal environment immersioning conditions were analyzed. The results show that hygrothermal aging significantly increases the lightning strike damage regions. While, the influence of stacking sequence on the damage forms is decreased. SEM results show that the fiber/matrix interfacial bonding is severely degraded by moisture.

Key words: composite, hygrothermal, lightning strike, microscopical mechanism
