Kinetic Energy Non-Lethal Weapons (KENLWs) are very similar to standard firearms, however, their projectiles differ in that the impact with the intended target is meant to cause incapacitating pain rather than serious penetrating injury and/or death. The objective of the project was to substitute the impacting face of existing KENLW projectiles with crushable materials to see whether the impact force on an instrumented load plate could be kept constant within the operational range of potential impact energies/velocities. Fifteen material/density combinations were evaluated using two different test methodologies: a quasi-static compression test, and, a low velocity drop test. Based on the performance of the materials in these tests, the materials were down selected to two materials at two densities for each. The final four test configurations, along with two commercial-off-the-shelf KENLW projectiles were evaluated using a high velocity, free flight impact test. For all of the tests conducted, the transmitted forces were measured and documented. The performance of the high velocity free flight test samples were compared to the imposed force limits of 5000-8000 N. To varying degrees these targets were achieve.
