Two new kinds of compound reactive fragments were designed and prepared, and the penetration tests of the compound reactive fragments against oil tank with diesel oil were performed. The compound reactive fragment is composed of shell, bare reactive fragment and coping. Bare reactive fragments prepared by high-temperature sintering in a vacuum container have two kinds of formulations, one is mixed aluminum powder with PTFE, another is mixed titanium powder with PTFE. Fragments were fired using 12.7 mm ballistic gun, and the penetration process against oil tank were recorded by high-speed camera. The experimental results show that two kinds of compound reactive fragment can penetrate through 6 mm thick oil tank and have obvious ignition effects. Comparing with inert fragments, compound reactive fragments have better capability of penetration and ignition.
