It has been tested and compared that the mechanical properties in the load of tension, compress and three-point-bending at the different temperatures of two kinds polymer bonded explosive JOB-9003 which were shaped by technology formation of isostatic liquid and mould pressing. Results show that the mechanical properties of two kinds of JOB-9003 are all most the same at 20 ℃, but from 35 ℃to 55 ℃ the mechanical properties of isostatic liquied pressing JOB-9003 is much higher than that of mould pressing JOB-9003.
