This study aims to investigate the effect of aluminum layers on the tensile strength of glass laminates having different types of notches. Glass fabrics laminates and hybrid glass fabrics and aluminum layers laminates have been manufactured through vacuum bagging process. Tensile strength tests were carried out for laminates without and with double V- and C-notches to investigate their residual tensile strength. An analytical model has been suggested to investigate the behavior of these laminates accommodating these notches. Moreover, the finite element analysis (FEA) with commercial software, has been used to predict the damage failure modes for notched laminates under tensile strength tests. Experimental results showed that the tensile strength decreased 33% and 48% after having C- and V-notches in glass/epoxy laminates, meanwhile the reductions were only (13% and 17%) and (8% and 10%) for glass/epoxy laminates that have one and two aluminum layers with C- and V- notches respectively. The comparison of the analytical model and experimental results of residual tensile strength was matching well. Further, numerical simulation results for damage failure modes are in accordance with experimental results both qualitatively and quantitatively for notched laminates under tensile load.
