Based on the requirements of material design and mechanical response of charge structure,ideal safety performance,detonation performance and mechanical performance can be obtained through the use of binder.Therefore,the forming density,compression strength,tensile strength and elastic modulus of HMX base polymer bonded explosive were tested for different viscosity characteristics of F2311 fluorine rubber.The results showed that the PBX195 of F2311 with a characteristic viscosity of 1.95dL/g had a tensile strength of 4.05MPa and a tensile strain of 1.56%,which was higher than that of other PBX formulations with a characteristic viscosity of F2311,and the tensile modulus of PBX195 was 0.668GPa,which was far lower than that of other PBX formulations with a characteristic viscosity of F2311.Therefore,it can be considered that F2311 with characteristic viscosity at 1.95dL/g was the most suitable for HMX base PBX formula,and its mechanical properties and molding properties were significantly improved.
