In order to understanding the influence of binder content on residual stress and mechanical performance of polymer bonded explosive(PBX), the residual stress of warm compacted 1, 3, 5-triamino-2, 4, 6-trinitrobenzene (TATB) based PBX, with binder content ranging from 0 to 11%, were measured by VKα based X-ray diffraction method and mechanical properties were measured by Brazilian test. A simplified model of TATB crystal packed with binder structure was introduced for verifying the experiment results only in one condition of temperature. Results show that: the residual stress in PBX without any binder exhibits tensile mode is tension stress, with the binder content increasing, the residual stress reduces gradually. While the content of the binder is added more than 5%, the tensile residual stress reduces seriously. While the content is added from 7% to 9%, the residual stress turns to performing as compressive mode, the mechanical strength increases gradually with the more binder. The calculated residual stress of PBX agrees well with the experimental results. The experiment results can provide a reference for the formula design of reducing residual stress in TATB based PBX.
