含纳米级铝粉的复合炸药研究

Research on Composite Explosive With Nano-Aluminium

铝粉的颗粒尺寸对含铝炸药的爆轰性能有显著影响 ,在以 RDX为主体的粘结炸药中 ,加入 2 0 %粒径为 5 0 nm的超细铝粉 ,得到的新型复合炸药 ,其爆轰性能及作功能力明显高于含 2 0 %粒径为 5 μm和 5 0 μm的复合炸药。

Particle sizes of aluminium have significant effect on detonation property of aluminium bearing explosives. We gained new composite explosive by adding 20% superfine aluminium with 50 nm particle size in bonded explosive with RDX as main explosive. The detonation property and power strength of the new composite explosive are clearly higher than that of composite explosives containing 20% aluminium with 5 μm and 50 μm particle sizes.
