The Influence of Steel Cover Thickness on Ballistic Performance of Confined TiC-TiB₂ Ceramic Tiles against the Impact of Long-Rod Tungsten Alloy Penetrator of 1.4 km · s^-1

Abstract:

By conducting DOP test to evaluate the ballistic performance of confined TiC-TiB₂ ceramic tiles against long-rod tungsten alloy penetrators under the impact of 1.4 km · s^-1, the influences of steel cover thickness on ballistic performance of TiC-TiB₂ ceramic til_{Subscript text}es laterally confined by heat shrinkage of medium-carbon-steel sleeves were investigated. The results of ballistic testing showed that the steel covers with the thickness of 1.5 mm and 3.5 mm failed to axially confined the ceramic tiles with the mass efficiency smaller than 2.0. Since the steel covers in thickness larger than 10 mm had a sufficient stiffness to support their axially confinement on the ceramic tiles and ensure the ceramic tiles with high integrity to ballistic impact by inhibiting the comminuted ceramic to sputter out, not only resulting in the limited room-making of the penetrators in the ceramic tiles for their penetration, but also more importantly yielding the intensified erosion of commuted ceramic to the penetrators, finally, the improved ballistic performance of the ceramic tiles was achieved with the mass efficiency larger than 2.5.
