Experimental investigation on the ballistic resistance of polymer-aluminum laminated plates

It is shown that the polymer layer order, nose shape and polymer mechanical behavior affects the performance of the polymer-aluminum laminated plates. The PC is much better than the PMMA in the bi-layer plates in terms of improving the ballistic resistance of the aluminum. Furthermore, the structures with the polymer placed in the impact side performed better than that in the back side for blunt-nosed projectiles, which is opposite to that for ogival-nosed projectiles. And the polymer-aluminum laminated plates with the PC placed in the impact side for blunt-nosed projectiles have advantages comparing with pure aluminum alloy at same mass in this study.
