摘要
为了显著提高AP/nano-Al(nAl)复合物的压力释放效率,降低燃烧时间,提出了一种制备AP/nAl/G/CuBi_(2)O_(4)(CBO)复合物的策略。密闭爆发测试结果表明,复合物的压力释放率和压力达到峰值时间都得到了显著改善;当添加石墨烯(G)(2 wt%)/CBO(5 wt%)时压力增加13.5%,增压速率增加51.1%。此外,利用激光点火装置和高速摄像系统对制备复合物的点火和燃烧性能进行了评估,结果表明G和CBO的引入成功降低了点火延迟并缩短了20 ms燃烧时间。综上所述,添加CBO和G能显著改善AP/nAl燃烧放热、峰值压力与最大增压速率。
In order to significantly improve the pressure release efficiency and reduce the combustion time of AP/nano-Al(nAl)composites,a strategy to prepare AP/nAl/G/CuBi_(2)O_(4)(CBO)composites is proposed.Under closed bomb combustion testing,the results showed that the AP/nAl/G/CBO composite exhibited a significant improvement in the pressure release rate and time to peak pressure;the pressure increased by 13.5% and the pressurization rate increased by 51.1% when G(2 wt%)/CBO(5 wt%)was added.Furthermore,the ignition and combustion performance of the prepared complexes was evaluated using a laser ignition device and a high-speed camera system;the results suggested that the introduction of G and CBO successfully reduced the ignition delay and shortened the combustion time by 20 ms.In conclusion,the addition of CBO and G significantly improved the AP/nAl combustion exotherm,peak pressure and maximum pressurization rate.
