Abstract
Making use of ballistic gun equipment, the effect was studied that dyneema fiber reinforced plastic (DFRP) target plates with different thickness was impacted by two different tungsten alloy spherical fragments. Firstly, according to the ballistic experimental results, the relationship between ballistic limit velocity and target plates area density was obtained. Besides, the empirical formula of ballistic limit velocity was built according to the dimensional analysis method, and the predictive value with the empirical formula was consistent with the experimental results. Secondly, the main failure mode and energy absorption mechanism were analyzed for DFRP target plates impacted by tungsten alloy spherical fragments. Also, the influence of target area density and initial velocity of the tungsten alloy spherical fragment on ballistic absorbing energy was obtained. The research results are valuable for designing fragment warhead and light armor protective structure.
