摘要
采用二维有限元模型分析了纤维四方、四方对角和六方三种排布方式下SiC/Ti-6Al-4V复合材料的横向力学性能。结果表明,在横向拉伸载荷作用下,纤维排布方式对基体的失效机理有重要影响,且纤维四方排布时复合材料的拉伸强度明显高于四方对角和六方排布时的拉伸强度。
Two-dimensional finite element models were adopted to investigate the transverse mechanical properties of SiC/Ti-6Al-4V composite with square, square diagonal and hexagonal fiber packing. The results show that fiber packing plays a key role in affecting the fracture mechanism of matrix under transverse tensile loading, and the tensile strength evaluated from square fiber packing is obviously higher than those evaluated from square diagonal and hexagonal fiber packing for the composite.
