摘要

Military vehicles were manufactured traditionally from expensive, heavy, high-strength armour plate steel. Modern ceramic composites are the new non-structural armour for combat vehicles. Major advantages are its significantly lower cost and greater protection and weight reduction of more than 50 per cent. MT sheds a light on the most important ceramic materials today for ballistic protection. Thanks to their ability to resist very high temperatures, hardness far greater than metals and their possession of some of the highest strength-and stiffness-to-weight ratios of any materials, ceramics are commonly used in engine coatings, missile and rocket components, specialised transparencies and armour, which remain the dominant military applications. This is to expand significantly, however, as R&D efforts around the world find novel ways of adding ductility and other desirable mechanical properties by combining them with reinforcing fibres in Ceramic Matrix Composites (CMCs). Also, new processing methods promise repeatable production of high-quality, very tough transparencies in complex shapes and large dimensions from materials that transmit both IR and visible wavelengths. Furthermore, creating new material architectures using na-notechnology promises materials that are strong and light, resist very high temperatures and chemical attack and are virtually unbreakable at the same time, a set of properties today considered mutually exclusive and, naturally, extremely attractive for military applications.
