基于有限元应力分析和强度准则以及纤维连续绕过孔边的约束条件,对含孔纤维增强复合材料单层极的纤维取向和密度分布进行迭代设计,结果表明:在平均纤维含量不变的条件下其拉伸强度取得较大幅度的提高。此研究结果可进一步用于含孔复合材料层合板的设计。
Based on the finite element stress analysis and strength criterion and the constraint condition that the fiber continuously bypasses the edge of the hole, the fiber orientation and density distribution of monolayer pole containing fiber reinforced composites are iteratively designed. The results show that when the average fiber content is constant Tensile strength under its access to a more substantial increase. The results of this study can be further applied to the design of porous composite laminates.
