Abstract
In order to explore temperature effect on mechanical properties and binding energy of polymer-bonded explosive (PBX), a molecular dynamics method and compass force field are adopted to periodically simulate high insensitive explosive TATB (1, 3, 5-triamino-2, 4, 6-trinitrobenzene) crystal and TATB/F2311 consisted of TATB and fluorine rubber (F2311) at different temperatures. The results show that: compared with those of the pure TATB, the mechanical properties of PBX are effectively improved, and its tensile modulus, bulk modulus and shear modulus are reduced evidently. With the increase of temperature, the rigidity of PBX reduces, the elasticity enhances, and the binding energies between TATB and F2311 tend to change complicatedly.
