【摘要】 总结了降感黑索今(I-RDX)及其高聚物黏结炸药(PBX)老化研究成果,从RDX晶体特性及其评价方法、I-RDX及其PBX老化前后的晶体特性、冲击波感度特性方面进行了综述,认为I-RDX晶体中不含奥克托今(HMX)或含有微量HMX、或机械混入少量HMX时,材料老化后的冲击波感度特性没有明显变化,最后对I-RDX晶体中HMX的影响机理进行了讨论。更多还原

【Abstract】 The ageing research of insensitive RDX(I-RDX)and polymer bonded explosive(PBX)were reviewed.The crystal characteristics of RDX and evaluation methods,and the crystal characteristics and impact sensitivities of I-RDX and I-RDX based PBX before and after aging were summarized.The impact sensitivities of I-RDX crystal without cyclotetramethylene tetranitramine(HMX)or with a little HMX,or with blending some HMX,have no evident change.Influence mechanism of HMX in I-RDX crystal was discussed.更多还原
