AI Technical Summary

Technical Problem

Traditional methods for testing the sensitivity of energetic materials consume large amounts of samples and have high error rates. They cannot achieve micro-dose, high precision, or quantification, and cannot observe the microstructural evolution and initial reaction process of materials under impact loads in situ.

Method used

Employing a pressure loading module, a common optical path module, and a synchronization control module, this system enables sensitivity testing of energetic materials ranging from milligram to sub-milligram scales. Dynamic pressure loading is applied via a diamond anvil cell, and multi-dimensional in-situ diagnostics are performed using infrared spectroscopy, Raman spectroscopy, fluorescence spectroscopy, and high-speed imaging components. The synchronization control module ensures time synchronization.

Benefits of technology

It enables precise and quantitative measurement of the sensitivity of energetic materials from milligram to sub-milligram levels, and simultaneously visualizes their dynamic response process. The test results are objective and highly repeatable, and are suitable for rapid safety assessment and detonation mechanism research of new energetic materials.
