The main objective of the present study is to implement a functionally graded materials (FGM) technique to reduce the hole effect in fiber reinforcement polymers. The tensile and fracture behaviors of conventional and FGM composites containing open holes have been investigated. Open-hole specimens having different hole sizes have been fabricated using a hand lay-up technique with different cross-ply stacking sequences and various numbers of layers to study the open-hole effect on their tensile strength. On the other hand, a three-dimensional finite element analysis with the Hashin model was implemented to observe the failure modes along each layer. Experimental and numerical data revealed that the FGM technique enhanced the performance of specimens in the presence of a hole by increasing the fibers around the hole area. Furthermore, the [0/90/0°] sequence has more tensile strength than [0/90]s and [0°/90°/0°/90°/0°] sequences. It can be concluded that the bearing capacity of cross-ply laminates is proportionally dependent on the ratio of the number of 0° layers to the number of 90° layers and inversely dependent on the specimen thickness.
