Investigation of penetration ability and aftereffect of Zr-based metallic glass reinforced porous W matrix composite fragments

Zr-based metallic glass reinforced porous W matrix composite was prepared into fragments and loaded with grenade to study on penetration ability and aftereffect of fragments by explosion experiment. The results show that the Zr-based metallic glass reinforced porous W matrix composite has high density and strength, and the explosive integrity and penetration ability can meet the requirements of the shrapnel preformed fragments; the deformation of the Zr-based metallic glass reinforced porous W matrix composite fragments during the penetration process is one of the main reasons affecting the penetration ability of the metallic glass composite fragments; if the penetration ratio is high enough, the detonation effect of the preformed fragments can ignite the quilt and oil tank behind the target.
