Thermographic Testing for Impact Damage of Airplane Composite

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.
