摘要：

Reaction energy, reaction rate, and extent of reaction were the influencing factors of the damage effect of reactive materials. To improve the destructive effects of the reactive material, we systematically studied the influence of multi-component co-addition on the material properties. Reaction energy, burning speed, specific volume of explosive, and reaction processes under high-speed impact of the two kinds of reactive materials (50W-35PTFE-15Al and 50W-35PTFE-10Al-5Mg) were investigated. Furthermore, we fabricated incendiary bullets with the reactive material core and tested their damage effect. The results showed that the addition of the Mg increased the reaction heat in oxygen atmosphere. Meanwhile, we observed that the addition of Mg accelerated the reaction rate of the reactive material over different experimental conditions, including the combustion of natural stacking powder and the deflagration of dense bulk material under high-speed impact. Moreover, under the impact loading, the extent of reaction was improved significantly by Mg addition. Even though the smaller explosive specific volume of the 50W-35PTFE-10Al-5Mg, an obviously improved destruction were caused by the 50W-35PTFE-10Al-5Mg incendiary due to the sufficient reaction.
