采用无溶剂挤出成型技术制备了含2，4，6，8，10，12-六硝基-2，4，6，8，10，12-六氮杂四环[5.5.0.0（5，9）.0（3，11）]十二烷（CL-20）、1，3，5，7-四硝基-1，3，5，7-四氮杂环辛烷（HMX）或CL-20/HMX共晶的复合改性双基推进剂。通过安定性试验、感度试验、燃烧试验和力学试验，对改性双基推进剂的性能进行了评价。拉曼光谱分析表明，CL-20/HMX共晶在90 ℃、10 MPa的轧制过程中稳定性受到部分破坏。甲基紫试验表明，含CL-20/HMX共晶、CL-20和HMX的CMDB推进剂显色时间分别为77、60和75 min。燃速试验表明，含CL-20/HMX共晶、CL-20和HMX的CMDB推进剂在8 ~ 18 MPa压力范围内，燃速分别提高1.82、4.67和4.67mm/s，压力指数分别为0.095、0.306和0.346。力学性能测试表明，含CL-20/HMX共晶的CMDB推进剂力学性能不一致，但抗拉强度比含CL-20的CMDB推进剂有所提高。这些结果表明，CL-20/HMX共晶是解决含CL-20推进剂安全性能和稳定性应用问题的潜在材料。
The composite modified double base (CMDB) propellants containing 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazatetracyclo[5.5.0.0(5,9).0(3,11)] dodecane (CL-20), 1,3,5,7-tetranitro-1,3,5,7-tetrazocane (HMX) or CL-20/HMX cocrystal were prepared by the solventless extrusion formation technique. The performances of CMDB propellants were evaluated by means of stability, sensitivity, combustion and mechanical experiments. Raman spectra analysis indicated the stability of CL-20/HMX cocrystal is partially destroyed in the rolling process under 90 degrees C, 10 MPa. Methyl violet tests revealed that the colored time of CMDB propellants containing CL-20/HMX cocrystal, CL-20 or HMX are 77, 60, and 75 min, respectively. Burning rate tests shown that the burning rates of CMDB propellants containing CL-20/HMX cocrystal, CL-20 or HMX in the pressure range of 8 to 18 MPa, increased 1.82, 4.67, and 4.67 mm/s, with the pressure exponents 0.095, 0.306, and 0.346, respectively. Mechanical property tests revealed that the mechanical properties of CMDB propellant containing CL-20/HMX cocrystal are inconsistent, but the tensile strength has improved compare with CMDB propellant containing CL-20. These results suggest that CL-20/HMX cocrystal is a potential material to solve the application problem of the safety performance and stability of the propellants containing CL-20.
