An Investigation into Ballistic Impact Behavior of Woven Panels Sahba Roohollahi s roohollahi@tx iut ac ir 8 January 2014 Department of textile engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisors M Zarrebini zarrebini@cc iut ac ir M Ghane m ghane@cc iut ac ir Abstract Armors as means of protection against weapons have been known to man since early history These materials have been through various stage of evolution with view to points such as ease of use comfort and degree of protection Since 1940s the use of lightweight armors compared to traditional types as physical barrier against bullets fired from hand held light weapons has increased Reduction in the mass of armors is of paramount importance This can be achieved by the incorporation of fibrous composite in structure of the armors In this research samples of composite armor were produced using fabrics woven using Kevlar fiber and bi component polyurethane resin Samples were fired at by frustum and plain pointed geometry bullets with gas gun set Ballistic limits for 8 and 12 layered fabrics when fired at by frustum projectile were found to be 118 and 144 m s respectively ABAQUS software was used to estimate the velocities of the projectile upon impact with the composite target panel and at the time exit from panel Model generated results were compared with the experimental results The effect of number of layers in the composite in relation to amount of absorbed energy by the armor was studied It was found that theoretical correspond well with experimental results Key Words Ballistic Kevlar Gas gun Abaqus Software Protection Armor Polyurethane
