Pressure Measurements of Aluminized Explosives Detonation Front with Different Aluminum Particle Size

Abstract:

Detonation pressure profiles in TNT/RDX and its mixtures with aluminum powders of different particle size have been studied with Manganin piezoresistance gauge. The measured detonation pressure accorded with the calculated detonation pressure. The results show that micrometer aluminum powders reacted with detonation at times of 0.5μs after the peak pressure. Aluminum powders did not react in the detonation zone, and introducing aluminum into explosive would reduce the detonation pressure. Compare with micrometer aluminum powders, nanometer aluminum powders reacted with detonation product more quickly.
