Abstract: In this work, a glass fibre reinforced composite laminates was developed for amour body application. Six samples of this composite laminates were formed with thicknesses of 28mm (Sample E), 24mm (Sample D), 20mm (Sample C), 16mm (Sample B), 12mm (Sample A), and 8mm (Sample F). These samples were targeted using two types of life bullets (Ogival and Conical nosed) moving at a velocity of 355m/s. Energy absorption capacity of these composite laminates was determined as a measure of area under the stress-strain curve through the application of the Simpsonís 1/3 rule. Sample E of the GFRP composite gave an optimum absorption energy capacity of 1.956 MJ after ballistic deformation (theoretical) which is greater than the kinetic energies of the conical projectile (456.676 J) and the ogival projectile (348.85 J) obtained from experimental analysis, energy absorption capacities of Samples A-D were also greater then these values. This indicates the ability of the developed composites (Samples A-E) to absorb the projectilesí kinetic energy without perforation.
