This research investigates ballistic responses of laminated Kevlar composite plates by using numerical simulations. Numerical simulation will be carried out for determining the ballistic responses of Kevlar/epoxy plates, which are commonly used for body armor. These composite plates are being impacted at velocities of between 50m/s and 1000m/s. Numerical parametric studies of the ballistic cylindrical projectile impact will be undertaken for obtaining an estimate of ballistic velocity limit, contact duration, and energy absorbed by the plate. The effect of diameter and mass of the projected projectile on ballistic limit velocity will be also studied. The material Kevlar is treated with shear thickening fluid (STF) and laminating the layers using polyester epoxy matrix. This paper also deals with the experimental and numerical investigation of the impact resistance properties of woven Kevlar fabrics impregnated with shear-thickening fluids (STFs) composed of fumed silica nanoparticles suspended in polyethylene glycol (PEG). The effect of STF impregnation on fabric are taken into account as the friction between the yarns and their crossovers and the friction between projectile and fabric during impact. STF is used to increase the impact strength of the neat woven Kevlar 29 by making the yarns more compact. Even though so many literatures have been done in this area but they are not working to reduce weight to the possible extent. Using Solid Works and finite element code LS-DYNA modeling and simulation have to be done respectively. Finally, the results obtained here should be compared with experimental data presented by another researcher.
