Abstract

Octogen(HMX)coated aluminum powder(Al)can effectively reduce its agglomeration and sintering phenomenon of Al and improve the combustion performance.Three kinds of Al/ HMX energetic composites(Al/ HMX-1,Al/ HMX-2 and Al/ HMX-3)with different morphology and structures were prepared by physical mixing method,solvent-antisolvent method and solvent evaporation-induced self-assembly method.Compared with the Al/ HMX-1 and Al/ HMX-2,Al/ HMX-3 has a spherical encapsulated structure with D₅₀ of 6.651 μm,and all components are evenly distributed.The Al/ HMX-3 composite has the best thermal decomposition performance and its decomposition peak of HMX is reduced to 264.3 ℃,which is ∼20.0 ℃ and ∼19.2 ℃ lower than that of Al/ HMX-1 and Al/ HMX-2,respectively.Combustion performance analysis shows that the Al/ HMX-3 composite burns violently and decreases its agglomeration and sintering phenomenon,and has the highest combustion heat and temperature.Through uniform coating of HMX,HMX decomposition provides oxidizing gas‘cage’for Al combustion in time to promote Al oxidizing and reduce agglomeration caused by collision between Al particles.As a result,the combustion performance and energy release efficiency of Al particles are greatly improved.
