Ballistic Penetration Response Of Glass Fibre Reinforced Polyester (Gfrp) Composites: Body Amour

Abstract: This work is aimed primarily at the development of armour protecting bodies for armoured vehicle technology, automobile, ship and aerospace industries. Samples of Glass Fibre-Reinforced Plastics (GFRP) composites were subjected to ballistic deformation. Detailed parametric studies considering conical and ogival nosed projectiles and the targeted laminate variables were carried out to find their effect on the response of the plate and the ballistic parameters such as ballistic limit and absorbed energy. This work shows that one of the governing factors in the damage resistance is the nose shape of the impacting projectile. The ballistic penetration test indicates that the conical nosed projectile has a higher penetration effect on the GFRP samples than the ogival nosed projectile, with Sample E showing the best penetration resistance. The ballistic limits, residual velocities, and ballistic energy were predicted for over a range of thicknesses of the armour protecting body.
