以短纤维复合材料的单纤维三维模型为基础，利用三维有限元方法，通过计算短纤维增强金属基复合材料中纤维在不同取向下沿纤维长轴方向的纤维轴向正应力和界面应力的分布情况，讨论纤维取向变化对基体和纤维间应力传递的影响。研究表明，随纤维位向角α的增大，基体与纤维间的应力传递程度下降，纤维的增强效果变差。同时，不同取向下的纤维附近有着不同的破坏机制，并与界面结合状态密切相关。
Based on the single fiber three-dimensional model of short fiber composites, the three-dimensional finite element method was used to calculate the fiber axial normal stress and interfacial stress distribution along the long axis of fiber in different orientations of short fiber reinforced metal matrix composites The situation, to discuss the changes of fiber orientation on the matrix and the impact of fiber stress transfer. The results show that with the increase of fiber orientation angle α, the stress transfer between the matrix and the fiber decreases, and the fiber reinforcement effect becomes worse. At the same time, there are different failure mechanisms in different orientations near the fiber, which are closely related to the interface bonding status.
