Investigation of Thermal Decomposition Kinetics, Safety and Performance Properties of PBXN-109EB

PBXN-109EB is a new plastic bonded explosive containing energetic binder system NHTPB NPB, RDX and Aluminum that has better performance and energetic properties than PBXN-109 with inert binder system. In this work, at first, morphology of PBXN-109EB was investigated by Scanning Electron Microscopy (SEM) and then thermal behavior and its kinetic parameters of thermal decomposition were extracted via kissinger method by Differential Scanning Calorimetery (DSC) technique in various heating rates. After wards, some of the safety tests for insensitive munitions (such as fast cook off, inductive explosion, bullet impact and fragment impact tests) were performed on the sample and approved its insensitivity. Moreover, lead block (trauzl) and dent tests for comparison betweenexplosion power of PBXN-109EB with PBXN-109 were performed. Results showed that the explosion power of PBXN-109EB enhanced 13 % and 33 % related to PBXN-109 based on trauzl test and dent test, respectively.
