CL-20基薄膜炸药的爆轰特性研究

Detonation Characteristics of CL-20 Based Thin Film Explosive

采用重结晶方法细化的CL-20炸药进行CL-20基薄膜炸药制备。研究了CL-20基薄膜炸药的爆轰性能、熄爆厚度和拐角效应,并与HMX基薄膜炸药进行对比。研究结果表明:在装药相对密度为85%时,CL-20基和HMX基薄膜炸药的爆速分别为8393 m/s和8069 m/s;CL-20基和HMX基薄膜炸药的熄爆厚度分别为0.23 mm和0.41 mm;相比HMX基薄膜炸药,CL-20基薄膜炸药的熄爆厚度更小,传爆能力更强。

The recrystallization refining CL-20 was used for the preparation of CL-20 based thin film explosive.Detonation properties,critical thickness of the explosive samples with different densities,and corner effect were researched and compared with those of HMX based thin film explosive.The results show that when the charge relative density is 85%,the detonation velocity of CL-20 based and HMX based thin film explosives are 8393 m/s and 8069 m/s,respectively.The quenching thickness of CL-20 based and HMX based thin film explosives are 0.23 mm and 0.41 mm,respectively.Compared with HMX based thin film explosive,CL-20 based thin film explosive has smaller critical thickness and stronger detonation transition capacity at the same charge relative density.
