The use of light weight armor against ballistic threats is very important for increasing mobility and survivability. This paper describes ballistic performance of an E-glass/phenolic composite as a function of laminate thickness and projectile impact velocity using mild steel core projectile. The results show that there is a nonlinear relationship between the energy absorption and laminate thickness. The effect of thickness and velocity on energy absorption in the laminates has been explained in terms of interaction time between target and projectile. It is also observed that deformation of the projectile is more dependent on the target thickness than the strike velocity. Changes in failure mechanisms with change in target thickness are also described. © 2015 Elsevier B.V..
