Effect of Aluminum Content on Fragment Velocity of Explosive Charge

In order to research the effect of Al content on fragment velocity of explosive charge, fragment velocity is tested and compared by airburst experiment when Al content ranges from 10% to 30% .The result shows that the explosive containing 20% Al has higher fragment velocity than other aluminized explosives in 2.5m and 3.5m distance. Explosives containing 20%～25% Al have higher detonation velocity and detonation heat.When Al content is 20%,explosive has higher fragment velocity during long distance because of higher detonation velocity and detonation heat.
