| 摘 要： | 采用光声光谱技术和差示扫描量热法研究了碳纳米管（CNTs）和炭黑（CB）掺杂对黑索今（RDX）激光点火特性的影响。结果表明：纯RDX在368mJ激光作用下，没有发生明显变化。经CNTs和CB掺杂处理后，RDX样品在很小的激光能量作用下就会发生分解，CNTs掺杂比cB掺杂对RDX的激光点火特性影响显著，在223mJ二者掺杂都存在一个最佳的点火延滞期。DSC分析表明掺杂后影响了RDX的热分析性能。

| Abstract: | Laser ignition characteristic of RDX doped with carbon nanotubes （CNTs） and carbon black （CB） were studied by photoacoustic spectroscopy （PAS） and differential scanning calorimetry （DSC）. No obvious change can be detected in pure RDX sample when 368mj laser energy was applied. Decomposition can happen in CNTs and CB doped RDX sample by the introduction of a very small amount of laser energy. The doping by CNTs has more significant effect than CB does on the laser ignition performance of RDX. An optimum ignition delay time can be observed in both CNTs and CB doped samples under 223mj laser energy. DSC analysis indicates the change of thermal properties in RDX due to the doping effect. |
