| 摘 要： | 三维编织中,编织纱线趋向于沿携纱器运动的方向运动。本文作者根据携纱器的运动规律,采用定义代表性控制域的方法,详细地研究了三维圆型编织中所形成的空间纱线交织结构。在此基础上,获得的预成型件结构单胞模型包含四种内部单胞和两种表面单胞。预成型件的整体结构可由六种单胞组装而成,且单胞的几何特性与其在预成型件横截面内所处的位置有关。单胞与预成型件具有相同的取向,有利于材料的力学性能分析。

| Abstract: | In the 3-D braiding procedure, the braiding yarn is tended to move along the direction of its carrier movement. Based on the movement of carriers, this paper presents a control region method to analyze the yarn traces systematically in 4-step 3-d tubular braided preforms. Then, four interior cells and two surface cells are established. For the whole structure of the preform, it can be assembled by these unit cells. The geometry of each cell is deeply dependent on its position in the cross-section of the preform. All cells are oriented in the same reference frame as the preform, which is quite suitable for the analysis of the mechanical properties. |
