摘　　要：由于飞机复合材料自身结构和制造工艺的特点,其冲击损伤破坏与金属材料明显不同。通过脉冲热像检测法,着重研究了低能冲击下飞机复合材料的损伤破坏特点,分析了飞机复合材料的冲击损伤源及其危害程度。结合飞机外场检测条件,就飞机复合材料损伤的原位检测提出了初步建议。Owing to the characteristic in material structure and manufacturing technology, the impact damage and failure mode of airplane composite is distinct from that of metal. Through thermographic testing, the damage and destroying characteristic of composite impacted by low energy object were researched, and the impact damage source and its potential harm to composite of airplane in service were analyzed. Some advice about in-situ testing methods for airplane composite in service were brought forward.
