高密度非晶金属基复合材料穿甲威力研究

Armor piercing power of high-density amorphous metal matrix composites

利用ANSYS和靶试研究高密度非晶金属基复合材料和93钨合金弹芯穿甲威力。结果表明:在弹芯着靶速度为(1400±20)m/s时,非晶金属基复合材料弹芯平均穿深为69.7 mm,单位穿深所需平均动能为625.3 J/mm,分别较93钨合金弹芯高20%和低17%;高密度非晶金属基复合材料具有更高的穿甲威力归功于材料更高的动态压缩强度和穿甲过程中的自锐行为。

The armor piercing power of high-density amorphous metal matrix composites and 93 tungsten alloy were studied by the software ANSYS and armour-piercing test.The experimental results show that the average penetration depth of amorphous metal matrix composites penetrators is 69.7 mm,and the average kinetic energy per penetration depth is 625.3 J/mm under the hit velocity(1400±20)m/s,which is 20%higher and 17%lower than that of 93 tungsten alloy cores,respectively.Analysis shows that the higher penetrating power of high-density amorphous metal matrix composites is attributed to the higher dynamic compressive strength and self-sharpening behavior during penetration.
