REVIEW STUDY ON MECHANICAL PROPERTIES OF HIGH VELOCITY IMPACT RESISTANT MATERIALS

Abstract

We find several materials which are resistant to high velocity impact projectiles. These materials are used in manufacturing bulletproof vest, bulletproof glass and several other ballistic applications. The determining factor for the materials to be classified as better high velocity impact resistant materials are their mechanical properties. This paper gives the readers a vivid idea about the mechanical properties a high velocity impact resistant material should possess. Due to the high impact strength and tensile strength materials like Kevlar and Carbon composites have they are widely used in ballistic applications. To explain the properties of these materials is the main of this paper. To resist high velocity impacts, these materials need high tensile strength and high impact strength. Alloys like steel and Titanium alloys also have high tensile strength and compressive strength which are also discussed about, in this paper. Few materials, like Kevlar, are classified under soft armour due to their light weight hence are most effectively used in bullet proof vest while, the hard armours are used in bulletproof structures and also in aerospace and military applications. In military aircrafts, materials like carbon composites are also used. Generally, steel is used as extra protection in certain bulletproof vests. In ancient times, alloys of titanium were found useful and were widely used in this aspect.
