氟化物与AP协同提升硼点火和燃烧性能研究
Enhancing Ignition and Combustion Reactivity of Boron through Combining Fluorides with AP
摘要
Abstract
To address the difficulties of ignition and the low combustion efficiency of boron(B),a range of boron-based com-posite energetic materials(EMs)was synthesized by integrating lithium fluoride(LiF),fluororubber(F14),and fluorinated graphite(CF)with ammonium perchlorate(AP),employing a strategy of synergistic enhancement via fluorine(F)and oxygen(O).The phase,morphology,and combustion characteristics of the composite materials were analyzed using X-ray diffrac-tion,scanning electron microscopy,a laser ignition system,and an oxygen bomb calorimeter.The findings indicated that the type and composition of fluorides markedly influenced the ignition and combustion efficacy of boron,which was ascribed to the variations in their fluorine release mechanisms and interactions with the B2O3 layer.Due to its layered structure and high fluo-rine content,the ignition delay time of B/CF(3.84％)was shorter(0.12s),and the combustion efficiency was higher(49.05％).The F-O synergy further enhanced the reaction kinetics and thermodynamics of boron and alleviated the carbon deposition problem during the reaction.AP@B/CF(3.84％)exhibited the shortest ignition delay time(～0.05s),the maxi-mum combustion heat(19 288J/g),and the highest peak pressure(265.87kPa).关键词
