我们始终追求改进的高能性能,例如所有高能化合物的高形成率、中等灵敏度和稳定性。1,3,5-三硝基四氢-1,3,5-三嗪(RDX)是一种经典的高能炸药,在军事和民用领域都有广泛的应用。本文应用CPMD方法研究了LAB对传统炸药RDX的爆轰作用。理论计算结果表明,由于LAB的引入,引发了大量的放热反应,表明储氢材料是一种很有前景的复合炸药助剂。
We always pursue improved energetic performances such as high formation enthalpies, moderate sensitivities and stabilities for all energetic compounds. 1,3,5‐trinitroperhydro‐1,3,5‐triazine (RDX) is a very classic high‐energy explosive which has been applied in both military and civilian fields broadly, whose combustion properties can be enhanced by introducing hydrogen‐storage compounds such as Lithium amidoborane (LAB). Here we apply CPMD method to study how LAB affects a traditional nitramine explosive (RDX) in a simulated detonation. The theoretical results show there are abundant exothermic reactions caused by the introduction of LAB, which suggests hydrogen‐storage material is a prospective assistant ingredient for composite explosives.
