This paper investigates the impact properties of Strategically Tuned Absolutely Resilient Structures (STARS) to establish their potential for use in energy transfer and storage applications. Ballistic tests were conducted on six (6), 20.3 cm × 20.3 cm (8 in. × 8 in.) reinforced cementitious composite plates having a constant thickness of 1.27 cm (0.5 in.). Each plate was reinforced with four (4) layers of graphite/Kevlar mesh. The energy absorption and mass reduction were recorded for plates impacted with projectiles traveling with velocities ranging from 9.5 m/s (31 ft/s) to 511 m/s (1678 ft/s). Although the number of samples was limited, a post-impact analysis was conducted to identify the ballistic limit from a limit velocity curve. In cases where the projectile partially penetrated or completely perforated the plate, spall consisted of relatively small particulates. No shear-plugging was observed in any of the tests.
