摘要
Abstract
In order to analyze the properties of TATB based polymer bonded explosive(PBX) at high temperature,the mechanical properties were measured at high temperature.The morphology of rapture section was observed by scanning electric microscopy (SEM).Results show that the PBX compressive strength,tensile strength,creep rupture strength and endurance time decrease with temperature increasing,while the Poisson ration keeps constant.The tensile creep failure model of PBX under 70 ℃ at 3 MPa is debonding between explosive crystals and binder,the failure model is facture of the PBX crystals at 50 ℃ and 60 ℃.关键词
