摘要
纤维增强金属层板兼具复合材料和金属材料的优点,是理想的民机结构备选材料。本文对玻璃纤维增强铝合金层合板在不同应力比下裂纹萌生及疲劳裂纹扩展性能进行了试验、测试和分析,获得了不同应力比及应力幅值对疲劳裂纹萌生和疲劳裂纹扩展的影响规律,给出了纤维增强铝合金层合板(FML)在疲劳载荷作用下疲劳特性,对此类材料的设计及应用有一定参考价值。
The fatigue and fatigue crack growth rate properties of Fiber Metal Laminates have been researched. By the analysis of test result, we acquired the regular pattern that fatigue crack and crack propagation effected by the stress ratio and stress level. We provide the fatigue characterisitics of FML under the fatigue loading, This is benefit to the FML＇s design and application.
