用单轴抗拉实验、动态力学分析仪和简支梁抗冲实验研究了不同3,4-二硝基呋咱基氧化呋咱(DNTF)/ RDX配比对DNTF/RDX改性双基(CMDB)推进剂(DNTF/RDX-CMDB，DFR推进剂)力学性能的影响。获得了-40 ℃下DFR推进剂的抗拉强度( σ m )、断裂延伸率( e m )及抗冲强度( a K )。根据“时间-温度”等效原理的WLF方程获得了DFR推进剂 β 松弛阶段的动态特征量黏弹系数( C 1 g )。分析了组分含量对各力学性能的影响和 σ m 、 e m 的变化规律。结果表明：低温下的 σ m 、 e m 和 a K 均与增塑剂含量间存在相关性。增塑剂含量减小，粘弹系数增加，NC分子侧基的“自由体积”下降，导致抗拉强度、断裂延伸率等力学性能降低。

The binder film of 3, 3-bis(azidomethy) oxetane-r-(glycidyl azide)(BAMO-r-GAP) copolymer/N100/IPDI system was synthesized using BAMO-r-GAP copolymer as pre-polymer, N100 and IPDI as curing agent and BDO as chain extended agent. The Fourier transform infrared(FT-IR) spectrometer, differential scanning calorimetry(DSC) and thermogravimetry-derivative thermogravimetry(TG-DTG) were used to characterize the binder film, and the mechanical properties was also measured. Results show that the tensile strength of the binder film is raised to 0.87 MPa, and the breaking elongation is above 106%. The glass transition temperature (Tg) of the binder film is about -50°C and the thermal decomposition starts at 217.0°C, which means the binder film has good thermal stability.

High performance liquid chromatography (HPLC) was employed to analysis the solubility of RDX in melting DNAN/MNA at the range of 87°C to 95.3°C. The optimal chromatography conditions were as following: mobile phase is methanol/water=6/4 (V/V), and flow rate 1.0 mL·min -1, and wavelength of detector 254 nm, and injection volume 5.0 μL. The influence of particle size, equilibration time and temperature programming on solubility was studied. Under the optimum condition, the curve of the solubility of RDX in DNAN/MNA as a function of temperature was built. Results show that the solubility of RDX increases with increasing of the temperature.
