| 摘 要： | 试验研究了复合材料层压板的铺层方向以及裂纹混合比对层间裂纹分层扩展的影响规律。试验结果显示: 在非0°单向板的 Ⅰ 型层间裂纹分层扩展过程中, 会出现层间裂纹穿过分层开裂面的铺层而偏离到相邻铺层间扩展的现象, 而0°铺层具有阻止该裂纹偏离扩展的作用; 在不同裂纹混合比的层压板分层开裂试验中, 相应的0°单向板的断裂韧性均可以作为下限值而偏安全; 混合断裂韧性( Ⅰ 型断裂韧性+ Ⅱ 型断裂韧性)随着裂纹混合比的变化呈现类似正弦曲线的变化规律。

| Abstract: | The effects of fiber angel orientation and mixed-mode ratio of interlaminar fracture on the properties of delamination were experimentally studied in the laminate propogates. The results show that 0°ply is able to stop delaminating from jumping into adjacent plies in mode Ⅰ interlaminar fracture; fracture toughness of unidirectional laminate at all mixed-mode ratios could be regarded as the conservative value; the curve of mixed-mode fracture toughness resembles sine as the mixed-mode ratio varies. |

| Keywords: | delamination fracture toughness fiber angel orientation mixed-mode ratio |
