Abstract

Abstract

Boron carbide (B₄C) ceramic has been widely used in armor fence due to its high hardness and low density. Ballistic performance of B₄C ceramic and its composite targets has been one of the focuses recently. Ballistic performance of B₄C ceramic composite targets defending 12.7 mm calibre armor-piercing bullets were explored through depth-of-penetration experiments and the corresponding numerical simulation model was established. The numerical simulation model for 12.7 mm calibre armor-piercing bullets penetrating into B₄C ceramic composite targets was verified through the comparison between numerical results and experimental data. The influences of target configuration, back layer thickness and type on the ballistic performance of the composite targets were explored. It can be figured out from the results that for the composite targets with same areal density, the thicker the ceramic target, the better its ballistic performance; the increasing rate in the ballistic performance of the ceramic composite target decreases when the areal density increases and the ceramic thickness keeps constant. Ceramic/polyethylene (PE) structures are more suitable for defending against penetration by low-velocity bullets, while ceramic/Al structures are more suitable for defending against penetration by high-velocity bullets.
