Abstract

In this article, the ballistic impact response of multilayered Carbon Fiber-Reinforced Polymer (CFRP) composite laminates supported with metals was investigated using the LS-DYNA explicit finite element software. The hybrid composite laminates were subjected to a high velocity ballistic impact by a round nose projectile. The implemented numerical model has been verified by comparison with the published experimental results of Ti6Al4V. Furthermore, the effect of different metal alloys including Al 2024-T3, Al 7075-T6, Al 6061-T6 and the stacking sequences were studied by using the verified numerical model. The final computational simulation results showed a good correlation with experimental results in terms of the deformation and damages of composite laminates.
