| 摘 要： | 以电场作为引燃条件对含能材料的分解过程进行了研究。利用黑索金(RDX)单晶结构,构建了镶嵌有碳纳米管(CNT)的黑索金(RDX)复合结构模型,利用反应分子动力学模拟研究了该材料在外电场下的响应。结果表明构建的复合结构在方向沿CNT 的匀强电场下,能够以CNT 为中心形成反应热点;随着热点的成长,形成了自发行进的燃烧层,可以分解掉整个体系。

| Abstract: | The decomposition process of energetic materials is studied using the electric field as an ignition condition. Using hexogen (RDX) single crystal structure, a composite structure model of RDX embedded in carbon nanotubes (CNTs) was constructed, and the response of the material under external electric field is simulated with reactive molecular dynamics (ReaxFF MD) simulation. The results show that the composite structure can form a reaction hot spot with CNT as the center under the uniform electric field along the CNT tube. With the growth of the hot spot, a self-issued combustion layer is formed, which can decompose the whole system. |
