The damage effect of Al/PTFE composite structural reactive fragments on the different types of double-layer targets is studied through the loading experiment with 14.5 mm ballistic gun. The empiricial formulas of penetration diameter in front layer plate and expanding perforation area on rear layer plate were established using multiple regression analysis. The results show that the penetration diameter in front layer steel or aluminum plate increases with the rising of impact velocity and target thickness in the range of 800-1 400 m/s. The penetration diameters in the steel, aluminum and carbon fiber composite plates are 1.25-1.62 times, 1.08-1.42 times and 1.13 times of fragment diameter, respectively. Expanding and tearing damages are caused to the rear layer aluminum plate or the carbon fiber composite plate by the ractive fragments. The expanding perforation area increases with the increase in front layer target strength and impact velocity, and the delamination of carbon fiber and resin matrix for the back of carbon fiber composite plate should be considered in damage assessment. The empiricial formulas were proved to be accurate and reliable, and the relative error was controlled within 5% through experiment.

A three-stage, including shock activation, self-propagation energy release, and secondary self-activation, model of impact-release energy of alloy fragments is proposed by observing the perforation pattern of steel target and the high-speed photographic image of the post-target impact-release fire zone.The activation threshold of fragment energy, the critical condition of complete energy release, the maximum size of energy release flare region and the effective damage distance behind the target were obtained by applying stress wave, thermal stress theory and shock temperature rise equation. The results show that the tungsten-zirconium-hafnium active alloy fragment not only has the kinetic energy damage ability similar to the inert fragment, but also has a little active energy consumption before the target is penetrated, and the active energy is completely released in a millisecond time regime after penetrating into the target. Before the fragmentation active energy is fully activated, the maximum damage volume and effective damage distance in the release energy flare region increase exponentially and linearly with the increase in fragmentation speed.

The deformation mechanism of the empty column is considered as plugging. The projectile is assumed to be a flat-ended cylinder without deformation. A new theoretical model of deformation is introduced, and based on the energy method, a theoretical formula is derived to estimate the ballistic limit velocity of the process. Numerical simulations of the penetration process of a blunt solid cylinder into the empty metal columns are performed using the LS-DYNA explicit solver. Different empty columns are used as the targets, and these columns are made from Weldox 460E steel and have different wall thicknesses (6, 7, 8 and 9 mm) and internal column edge lengths (60, 70, 80 and 90 mm). To validate the derived relation for the ballistic limit velocity, the results of the numerical simulations are compared with the corresponding theoretical predictions. Finally, the effects of some geometrical characteristics such as projectile diameter and mass on the perforation process and the ballistic limit velocity are discussed.
