采用浇注固化工艺成功制备了HTPB/CL-20浇注式传爆炸药。采用扫描电子显微镜（SEM）和电荷密度测试表征HTPB/CL-20炸药的成型效果。对HTPB/CL-20炸药的传播可靠性、爆速、机械感度、热分解特性和热稳定性进行了测量和分析。结果表明，当CL-20含量小于91wt.-%时，容易获得成型效果较好的炉料。 HTPB/CL-20炸药的临界直径小于1 mm，具有良好的传播可靠性。当含91 wt.-% CL-20的HTPB/CL-20装药密度为1.73 g cm−3时，其爆速可达8273 m s−1。而且这种炸药机械感度低，热稳定性好。
HTPB/CL-20 castable booster explosives were prepared successfully by a cast-cured process. Scanning electron microscope (SEM) and the charge density test were employed to characterize the molding effect of HTPB/CL-20 explosives. The propagation reliability, detonation velocity, mechanical sensitivity, thermal decomposition characteristics and thermal stability of the HTPB/CL-20 explosives were also measured and analyzed. The results show that, when CL-20 content is less than 91 wt.-%, the charges with better molding effect were obtained easily. The critical diameter of HTPB/CL-20 explosives is less than 1 mm, which exhibits good propagation reliability. When the density of HTPB/CL-20 charge with 91 wt.-% CL-20 is 1.73 g cm−3, its detonation velocity can reach 8273 m s−1. Moreover, this kind of explosives has low mechanical sensitivity and good thermal stability.
