摘要: 本文用以高密度光栅技术为基础的云纹干涉法对带双边裂纹的CALL混杂复合材料进行了拉伸实验研究,得到了在纤维方向和垂直纤维方向拉伸时双边裂纹尖端损伤区的形状及其应变场分布。结合对试件断口形貌的扫描电镜观察,分析了两种拉伸试件的破坏模态。所得实验结果为进一步深入研究CALL混杂复合材料的损伤和破坏机理提供了重要依据。

Abstract: The mechanical behavior in damage zones around crack-tips for carbon fiber aluminium laminates (CALL) hybrid composites was studied by moue interferometry.The strain distributions in the zones around the double-edge crack-tips for longitudinal and transversal specimens were obtained under the tensile loading.The morphology of damaged sections was observed by use of scanning electron microscope and the damage characteristics were analysed for these specimens.
