Abstract
In this chapter, configurations of ceramic-composite armour for resisting ballistic impact shall be introduced. Mechanics of impact shall be explained. Penetration, perforation, and various energy-absorbing mechanisms shall be enlisted. Relative contributions of multiple parameters to penetration resistance such as material properties and geometric configurations shall be discussed. A range of materials can be used for armour. Effect of the choice of material on aspects such as armour weight and thickness shall be included. Key issues of concern while designing ceramic-composite armour such as relative thicknesses of constituents, shape of ceramic tiles, and their sizes shall be discussed. A few probable approaches for improving energy absorption during impact and post-impact residual strength such as use of layered ceramics, embedding nanofillers, and improving toughness of the composite matrix shall be presented. Aspects of multi-hit resistance in ceramic-composite armour and key challenges encountered by armour designers to achieve multi-hit capability shall be discussed. In closure, shortcomings in currently used ceramic-composite armour design and envisioned future trends for improving its performance shall be highlighted.
