摘要
制备了碳纳米管修饰的钨系延期药,用扫描电子显微镜对碳纳米管在延期药复合物中的分布状态进行了表征,并对不同加入量的碳纳米管对钨系延期药延期时间的影响进行了研究。结果表明:碳纳米管的加入明显提高了钨系延期药的燃速;另外,碳纳米管的加入能够改善钨系延期药的点火可靠性,在相同的制备和装药压力下,碳纳米管的加入能够使延期药可靠发火。
The tungstenic delay compositions modified by carbon nano-tube（CNTs） was prepared. The distribution of CNTs in the compositions was studied by scanning electrical microscope （SEM）. The influence of different CNTs content on the delay time of delay composition was researched.The results show that the addition of CNTs in the delay composition can obviously increase the combustion velocity and the ignition reliability of delay compositions.
