- Abstract
- A study is presently underway to evaluate the performance of selected polymeric composites as spall liners. An evaluation methodology as well as experimental results are presented. A Velocity Merit Rating (VMR) is used to rate the composites for a given areal density of 15 kg/m square based on V50 PBL (Protection Ballistic Limit) results. It is found that E Glass fiber reinforced plates rate the poorest (VMR=1.0) whereas Spectrashield plates have the highest rating at 2.42. The materials were also tested in a contract spall liner configuration with 1/4-inch RHA steel base armour. THe 0.50-inch AP M2 projectile fire at full charge was used as the threat. Velocity measurements reveal that the residual velocity is on average 9.5% lower than that of the impact velocity. Witness pack data shows that the polymeric composites are much more efficient at mitigating behind-armour debris rather than stopping the main penetrator. The evaluation also makes it possible to demonstrate the superior performance of plates that have been designed for ballistic applications.
