Modern body armour relies on dense plates of brittle ceramics fracturing under ballistic impact loads to protect personnel from ballistic injuries. The problems with these systems are that they are heavy and that a large proportion of the energy from the projectile is transmitted to the body resulting in blunt force trauma injuries that can be fatal.
This project aims to build on existing ACCIS research by experimentally testing a promising geometry of ceramic platelets in an arrangement similar to that observed in nacre, an impact resistant material found in nature. An additive layer manufacturing process is employed to simplify the production of the complex geometry used by the ceramic platelets. Impact tests are used to investigate the performance of the design and determine its suitability as a new design philosophy for impact resistant body armour.
