铅对粉末药型罩性能的影响
Influence of Lead on the Performance of Powder Shaped Charge Liner
摘要
Abstract
In order to study the influence of lead powder on the properties of the copper-tungsten shaped charge liner,the experiments are carried out by adding 5%-20% of the lead powder to the original copper-tungsten liner.The results show that the addition of lead can reduce the porosity of liner;and with the increase of the amount of lead powder,both the penetration depth and the entrance aperture increase firstly and then decrease after reaching the maximum values when the lead content is 10%-15%.The reasons for this phenomenon are analyzed in detail from the liner molding,jet formation,stretching and penetration.Consequently,a reasonable explanation for the influence of lead powder on the properties of the copper-tungsten powder shaped charge liner is presented.The results provide a theoretical basis for making use of lead powder instead of bismuth powder to improve the penetration performance of copper-tungsten powder liner.关键词
