采用Pro/E作图软件和ANSYS模拟软件对三维深角联结构的Kevlar/PA复合材料进行纬向拉伸模拟分析并进行实验验证。结果表明:材料沿纬纱方向加载2mm拉伸位移载荷时,纬纱是承载主体,经纱次之;造成材料失效的主要区域为哑铃状试样平行段的末端;经纱对于材料的破坏有一定的延缓作用;实验验证的材料破坏区域与模拟结果吻合。
Pro/E mapping software and ANSYS simulation software was used to analyze and experimentally verify the Kevlar/PA composite materials of 3D deep-angle joint structure.The results showed that when the material was loaded 2mm stretch displacement load along the direction of weft yarn,the weft yarn was carrying body and warp yarn was the second.The main area causing the material failure was the end of the parallel segment of the dumbbell-like specimen,and the warp yarn had a certain delay effect on the destruction of the material.In addition,the experimentally verified material destruction area was consistent with the simulation results.
