Fiber reinforced polymer composite (FRPs) materials are widely used for joining bolted, riveted and pinned in aerospace and aircraft industries due to their engineering properties such as high strength, high damping, low weight and low thermal expansion. However, the structure of FRPs is more complicated than metals, the factors during the drilling process such as hole entry and exit delamination, matrix phase distortion and fiber breakage lead to the reduction of the engineering properties of these materials. These materials is stacked with metals such as titanium and aluminum for drilling operation, especially on body-wing connections in the aerospace and aircraft industries. Each stacked materials is required to determine the optimum cutting conditions for precision surface quality due to its different characteristics during drilling. In this study, the results obtained from studies are presented together regarding to the drilling operation of stacked with metals and unibody FRPs in literature.
