Abstract

Numerical modeling is one of the essential tools for predicting the ballistic impact strength of hybrid polymer composites without damaging the sample. The purpose of this work is to analyze the ballistic behavior of carbon/glass fibre reinforced epoxy-based composites. To investigate the effect of stacking order, modeled two different laminates containing carbon fibre and glass fibreto predict the impact behavior. High-velocity impact tests were performed with mild steel projectiles with high impact velocities. Finite element modeling was used to analyze the tensile, flexural and ballistic impact behavior of all laminates. The impact strength of laminates is evaluated using various stress plots. The results showed that the ballistic resistance was mainly affected by the fibre stacking order, fibre type, fibre orientation, and laminate thickness.
