摘要:
为了提高n-Al/MoO3纳米铝热体系的增压能力，改善能量释放性能，合成了高能产气组分硝酸四氨合铜（TACN），并将TACN复合入n-Al/MoO3体系中。利用扫描电子显微镜（SEM）、X-射线衍射（XRD）技术研究了复合材料的形貌和微观结构。采用差示扫描量热仪-热重分析（DSC-TG）联用技术探讨了各体系的热反应路径。使用高速摄像机和密闭爆发器分析了纳米铝热体系的火焰增长与传播和压力输出特性，评估了TACN的加入对n-Al/MoO3体系的能量释放速率和增压性能的影响。研究结果表明：n-Al/MoO3体系中加入的TACN能够在铝热反应的温度前放热分解，有效活化纳米铝与金属氧化物间的界面，从而降低体系的初始反应峰温度。此外，TACN的加入显著增强了n-Al/MoO3体系的能量释放和压力输出性能。当TACN的质量分数为6%时，n-Al/MoO3体系的火焰增长速率和火焰传播速率分别增加了32%和30%，峰值压力和增压速率分别提高了26%和70%。综上所述，TACN可提升n-Al/MoO3纳米铝热体系的压力输出，并调控体系的能量释放性能。
Abstract:
In order to enhance the boosting capability and improve the energy release performance of n-Al/MoO3 system, tetraamminecopper nitrate (TACN), a high-energy and gas-producing component, was synthesized and incorporated int n-Al/MoO3 system. The phases and microstructures of composite materials were investigated using scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. The thermal reaction pathways of each sample were explored by DSC-TG. High-speed photography and a closed bomb apparatus were employed to analyze the flame growth, propagation, and pressure output characteristics of the system, assessing the impact of TACN incorporation on the energy release rate and boosting performance of n-Al/MoO3 system. Results indicate that the introduced TACN in n-Al/MoO3 system can decompose prior to the aluminum exothermic reaction temperature, effectively promoting the activation of the interface between nano aluminum and metal oxides and reducing the main initial reaction temperature of the system. Furthermore, the introduction of TACN significantly enhances the energy release and pressure output performance of n-Al/MoO3 system. When the mass fraction of TACN is 6%, the flame growth rate and flame propagation rate of n-Al/MoO3 system increase by 32% and 30%, respectively, while the peak pressure and boosting rate elevate by 26% and 70%, respectively. In conclusion, the addition of TACN can enhance the pressure output of n-Al/MoO3 system and regulate the energy release performance of the system.
