研究了由四步 1∶1法编织的三维四向矩形复合材料预成形件内部纱线之间的接触情况 ,找出了内部纱线上接触点的分布规律和纱线间传力特点。确定出有关的几何参数值和内部纱线有限单元及节点的一种新取法。
The contact between the yarns inside the three-dimensional four-way rectangular composite preform weaved by the four-step 1: 1 method was studied. The distribution of the contact points on the inner yarns and the force transmission between the yarns were found out. Determine the geometry parameter values and internal yarn finite element and node a new method.
