铝壳型高氯酸铵@铝复合含能材料的点火燃烧性能
Ignition and Combustion Performance of Aluminum-shelled Ammonium Perchlorate@Aluminum Composite Energetic Materials
摘要
Abstract
Aiming at the critical problems that aluminum(Al)powder is prone to agglomeration during the combustion of solid propellants,and the insufficient contact between Al powder and ammonium perchlorate(AP)oxidizer leads to incomplete combustion,an interfacial assembly strategy of aluminum-shelled AP@Al was proposed.AP@Al composite energetic materials were prepared by glycidyl azide polymer(GAP)-mediated coating process.The coating morphology,thermal decomposition behavior and ignition-combustion characteristics were characterized by scanning electron microscopy-energy dispersive spec-troscopy(SEM-EDS),thermogravimetric(TG)analysis and laser ignition-combustion experiments.The results show that the prepared AP@Al composite energetic materials achieve relatively uniform adhesion of Al particles on the AP surface.The inter-facial interaction between AP and Al can promote the high-temperature decomposition of AP and make the decomposition process more concentrated.Compared with the physically mixed AP/Al sample,the ignition delay time of the AP@Al sample is shortened by 4.9ms,and the flame expansion rate and combustion intensity are significantly improved,which can effectively inhibit the agglomeration of Al powder.In addition,the combustion mechanism of AP@Al is obviously different from that of AP/Al.关键词
