采用Pro/E绘图软件绘制Kevlar/PA装甲材料的结构模型,并利用ANSYS Workbench分析材料在拉伸位移载荷作用下的破坏区域及力学响应。结果表明:三维深角联Kevlar/PA装甲材料在拉伸载荷作用下,经纱为主要承载体,纬纱为次要承载体,树脂承载最少。材料发生拉伸破坏的模式为部分经纱断裂,以及树脂与经纱、纬纱的脱粘。材料中应力分布较大区域与材料结构中的经纱走向关系密切。材料破坏区域出现在离中心界面10mm处的经纱上。
Pro/E drawing software was used to draw the structure model of Kevlar/PA armor material,and used ANSYS Workbench to analyze the material's failure area and mechanical response under tensile displacement load.The results shown that under the tensile load of the three-dimensional(3D) deep-angled Kevlar/PA armor material,the warp yarn was the main carrier,the weft yarn was the secondary carrier,and the resin load was the least.The mode of the tensile failure of the material was part of the warp yarn breakage and the debonding of the resin,the warp yarn and the weft yarn.The area with large stress distribution in the material was closely related to the warp direction in the material structure.The material failure area appeared on the warp yarns 10mm from the center interface.
