Abstract: Metal-granite composite material can overcome inherent defects of traditional concrete and has good mechanical properties, such as resistance to high pressure,tension,shearing strength, impact toughness. For studying the abilities of resisting high-speed penetration, a series hypervelocity penetration experiments were conducted. Experimental results indicate that metal-granite composite material has perfect ability to resist hypervelocity penetration. The high impact toughness and interior asymmetry characteristics can make mass loss, bend, fragmentation, disaggregation and penetration track deflection etc which occur in penetration. Metal-granite composite material can be considered as perfect bursting layer.
