Sensitive mechanism analysis of energetic materials
Amino-nitrobenzofuroxan is a compound designed according to the molecular structure characteristics of TATB and BTF. It has the advantages of excellent thermal stability of TATB, low sensitivity and high detonation energy of BTF, and is referred to as ANBDF. ANBDF has potential application prospects in blunt impact plate detonators and blunt detonators. In this paper, the structure, electron behavior and absorption characteristics of ANBDF crystals are investigated in the pressure range of 0-110 GPa using the quantum mechanical method of CASTEP. The band gap is 0 at 70 GPa, with the highest sensitivity. The results of this study are conducive to further understanding the behavior of ANBDF under high pressure.
Propellant formulation simulation evaluation
The physical compatibility of various components in high energy solid propellant is an important index to evaluate the reliability and storage stability of solid propellant.
In order to improve the bond strength between the interface of oxidant and adhesive in solid propellant; It is necessary to design and screen bonding agents with excellent performance, but the experimental method is low efficiency and high cost. Using the molecular simulation of Forcite for kinetics, the compatibility of different components can be quickly screened and the bonding mechanism can be studied in depth.
