Armors designed to defeat small caliber projectiles, as are typically required for lighweight aircraft or vehicle protection, can vary greatly in design, weight, and cost depending upon the materials chosen. Where weight is a primary consideration, ceramic/composite armors provide the best performance. Typical materials used today for ceramic/composite armors include Spectra 900 and 1000, Kevlar 23 and 49, and S-2 Glass fibers as well as boron carbide (B4C), silicon carbide (SiC), and aluminum oxide (Al2O3) ceramics. Because there is such a range of materials available, an armor system can be tailored to meet the specific design requirements of any given application. These design requirements may include weight, cost structural loading, thermal exposure, shock, vibration, flammability, and solvent resistance, just to name a few. Each material evaluated has is own advantages and disadvantages which may lead to the selection of one material over another. This paper will examine typical design trade-offs for a number of ceramic/composite armor systems based on their exhibited properties and intended use.
