摘要
探讨了羽界面下短纤维增强复合材料性能的改善．比较了哑铃状与平直短纤维两种复合材料模型．讨论了不同的基体与纤维强度比值下哑铃状材料模型的有效性．经有限元数值计算后得知：弱界面条件下，哑铃状材料模型可较大地提高复合材料的性能；基体与纤维强度比值越小，材料性能的改善越大。
The improvement of short-fibre reinforced composite materials under weak interface was discussed. Comparison between plain short-fibre model and dumbbell short-fibre model has been done. Effectivity of dumbbell model under different strength ratios of mains to fibre was discussed. born abate element analysis it was concluded that dumbbell model could well improve the performance of composite materials with weak interface. The lower strength ratio of mains to fibre, the better -improvement is.
