| Research Abstract |
The air-leakage detection system for space-debris impact was experimentally investigated. The mechanochromism metal complex that becomes luminescent due to the rapid increase of temperature and pressure was applied to pressurized chambers. We selected the glue that can remain on the aluminum bumper even after the hyper-speed impact. Consequently, the mechanochromism metal complex was shown to survive and remain on the bumper, instead of being peeled, after the impact shock. Furthermore, using a spectral instrument, we confirmed that both Fe complex and Eu complex had a significant alternation in emission spectrum after the hyper-speed impact.
