Comparison Of Al2O3, SiC, and B4C as Ballistic-Resistant Body Armor

Sonia Aprilya, Sovian Aritonang


Ceramic armor materials are intended to protect people and vehicles from ballistic damage. Currently, emphasis is placed on developing ceramics with properties that are difficult to achieve, such as high ballistic performance and low weight. The development of ceramic materials over the past three decades has resulted in continuous improvements in their properties and structural uniformity. However, the relationship between these properties and the ballistic performance of ceramics remains unclear. This article reviews the current understanding of the failure stages of ceramic armor and methods for assessing ballistic performance. A comparison is made between aluminum oxide and silicon carbide and boron carbide. Although the development of ceramic materials has actively contributed to improving their properties, their relationship with ballistic performance remains a mystery. This study attempts to gain further insight into the failure stages of ceramic armor and how to evaluate its performance. A comparison was made between three major ceramic materials: alumina, silicon carbide, and boron carbide to better understand their properties and potential applications in ballistic protection.
