Abstract

An experimental study on the ballistic limit velocities (v50) of tungsten alloy spherical fragment penetrating Ceramic/DFRP composite target plates were carried out. Firstly, the tungsten alloy spherical fragment impacted different thickness ratio of ceramic/DFRP composite target plates were studied by using ballistic gun equipment. According to the ballistic experimental results, the relationship between ballistic limit velocity (v50) and area density (AD) of composite target was obtained. Secondly, according to the dimensional analysis method and the similarity theory, the simulation law of tungsten alloy spherical fragments penetrating ceramic/DFRP composite target plates was researched. Based on the above results, the empirical formula of ballistic limit velocity v50 was built. The predictive value using the empirical formula was consistent with the experimental results. The research results were valuable for designing fragment warhead and light armor protective structure.
