Ceramic materials are commonly used to provide ballistic protection for civilian and military vehicles, aircraft and personnel. Ever since the 1960s their relatively low densities and high hardness values have been attractive to armour designers. However, ceramic materials are inherently brittle and therefore careful thought must be given to the way in which they are applied. The penetration mechanisms of different projectiles into these materials are quite complex! Understanding the way in which these materials interact with the projectile is central to the development and design of an efficient armour system. This book intends to bring together some of the more pertinent lessons learnt over the years. It also intends to provide an insight into the penetration mechanisms of various projectiles into these armour materials. This book is primarily aimed at the military student, end user and enthusiastic amateur alike who are interested in a fundamental insight into ceramic armour. The content is based loosely on the author's notes compiled for various post-graduate defence technology courses and short courses on survivability - where the students have been mostly serving military officers.
