摘要
为了同时提高可燃药筒的力学性能与燃烧性能,以含能纤维作为可燃药筒的增强组分,制备了一组新型可燃药筒,并对所制药筒进行了力学性能和燃烧性能的测试研究。结果表明,含能纤维的引入,可有效提高可燃药筒的力学性能;有利于药筒的点火,同时提高了药筒能量,使药筒燃烧速度加快,燃尽时间缩短,且随药筒中含能纤维含量的增加,这种趋势更为明显;而从枪弹模拟射击试验结果推论,与对比配方相比含能纤维可燃药筒能降低装药燃烧产生的固体残渣和可燃气体,减弱射击特性信号。
In order to improve mechanical properties and combustion performance simultaneously, novel combustible cartridge eases were manufactured by adding energetic fibers as reinforcement component. The mechanical properties were characterized by compression and tensile strength, and combustion performance was evaluated by closed-bomb and gun charge cartridge tests, Results show that these novel combustible cartridge cases have good mechanical properties, and combustion performance is also improved. With increasing of the energetic fibers content, the ignition time and burning-off time are shrunk more and more, and the burning rate and impetus of the ease are increased gradually. Compared with the original ones, fewer solid residues and combustible gas are found in gun charge cartridge tests, which means adding energetic fibers could decrease the shooting features.
