700732号飞机座舱盖爆破故障分析

Failure Analysis of Canopy for 700732# Aircraft

本文用断口分析、红外光谱、能谱、电子探针和材料力学性能检测等手段,对残骸玻璃进行了分析判断,认为:座舱盖是在撞击力作用下空中爆破的。

The failure reason of the canopy was analyzed by the method of fracture surface analysis, infrared spectrum, electron probe, energy spectrum and mechanical testing. The results show that it is the force by some object that lead to the rupture of the acrylic plastics.
