    摘要:

    为了研究含有纤维的无壳弹发射药安全性,通过测试含有碳纤维素(CF)或精制棉的无壳弹发射药5 s延滞期爆发点、撞击感度和模拟枪膛试验的自燃温度,分析碳纤维含量、长度和精制棉对无壳弹发射药安全性能和模拟枪膛试验的自燃温度影响。实验结果表明: 无壳弹发射药中加入0.5%~1.5%、长度为10 mm的碳纤维有利于降低撞击感度; 纤维的加入提高了无壳弹发射药的耐热性,在相同温度下延长抗自燃时间。

    Abstract:

    The effect of refined cotton, carbon fiber content and length on the safety of caseless ammunition and self-ignition temperature of simulating bore test was analyzed by testing the ignition point of 5 s delay of the propellants containing carbon fiber or refined cotton,impact sensitivity and temperature of simulating bore test. Results show that the impact sensitivity of the caseless ammunition is depressed when adding carbon fiber with content of 0.5%-1.5% and length of 10 mm, the anti-spontaneous-combustion temperature is hoisted by adding carbon fiber and the anti-spontaneous-combustion time is prolonged at the same temperature.
