Abstract
In order to investigate the effects of binder component on the creep properties of TATB-based polymer bonded explosive ( PBX),tensile creep properties,compressive creep properties and three-point bending creep behavior of TATB-based PBX were studied by electronic universal testing machine and dynamic mechanical analyzer, respectively. Results showed that creep resistance performance was improved by the addition of reinforcing agent( styrene copolymer)with high glass transition tempera-ture and high mechanical strength. The creep strain of modified formulation was decreased,creep failure time prolonged. The creep damage time of original formulation obtained by 50 ℃/3 MPa tensile creep,70 ℃/10 MPa compressive creep and 70 ℃/6 MPa three-point bending creep tests were 14,12. 7,12 min,respectively. However,modified formulation did not rup-ture under the same conditions. Based on time-temperature superposition principle,the master curves of TATB-based PBX and its modified formulation were obtained at reference temperature of 60 ℃. Compared with original formulation,the creep compliance master curves of modified formulation shifted downward and the creep resistance performance was enhanced.关键词
