-----------------------------------------------------------------------------****--------------------------------------------------------------------------Abstract - The review article of this paper represents the reduced availability of natural resources, the increasing costs of production, and the apparent limit to our ability to fabricate high strength-to-weight metallic components necessitated the development of new materials to meet the demands of aerospace technology. These materials are called advanced composite materials and will be used to replace some of the metals currently used in aircraft construction. Advanced composites are materials consisting of a combination of high-strength stiff fibers embedded in a common matrix (binder) material, generally laminated with plies arranged in various directions to give the structure strength and stiffness. The much stiffer fibers of boron, graphite, and Kevlar have given composite materials structural properties superior in strength to the metal alloys that they have replaced.

Composite material is a material or alloy mixture with the reinforcement and made from two or more essential materials with pointedly different physical or chemical properties that, when combined, produce a material with physiognomies different from the specific components. The specific constituents remain separate and distinct within the finished structure. The novel material may be favoured for many reasons: common examples include materials which are stronger, lighter, or less expensive when associated to traditional materials. More recently, researchers have also commenced to actively include sensing, actuation, computation and communication into composites, which are known as Hybrid Materials.

Composites For Armour Solutions role of Armour is to protect a person, structure or device Achieved by absorbing kinetic energy of the projectile ™Energy may dominantly be absorbed by plastic deformation and/or fracture processes ™Fragments as a result of fracture process should not cause damage to what is being protected and should be arrested by another layer at the back. Armour plate may have to fulfil two roles: a protective role and structural role ™Both roles can be fulfilled by having sufficient strength at high strain rate and appropriate thickness to provide both protection and structural requirements of the Platform (Integral Armour /Structural Armour).Desirability of composite solutions for armour‐ better mobility and
