- The concept of producing efficient armour design focus on composites materials, since it has a high strength to weight ratio. Composite armour shows several advantages like resistance against high level stress and decreased shear deformations. Even though polymer matrix composite has a good resistance towards impact velocity, the damage was the most frequent problem that a composite material faces. Smart material integration in the composite has a tremendous effect on industrial field. In this study, damage mechanism of the composite laminate made of Kevlar/PVC foam board, polycarbonate board, shape memory alloy (SMA) wire were investigated. With reference to the damage analysis best results was achieved by embedding SMA as reinforcement to the laminate. The sandwich layer consist of SMA has a more resistance against impact failure. Here martensitic transformation of superelastic wire helps to dissipate the kinetic energy of the projectile to a large extent uniformly throughout the structure and prevent the laminate. SMA has an excellent energy absorbing capacity against impact velocity.
