In modern application in automotive and aerospace engineering especially in defense vehicle, underwater vehicle and aircraft used Metal and Polymer Composites as the main materials in their invention parts. The joining strength may increase if the contacted surface area between two materials is also increase, in this case, the relationship of adhesive joining between Aluminum and Glass Fiber Reinforced Epoxy have been investigated by using Finite Element Method (FEM). Four design specimens with different contacted surface area at Aluminum part. As an interpretation result, the cross-sectional area and the volume of fascinating profile at the joining Aluminum – GFRP which is resist the loading force is significant effect the tensile strength of the adhesive joining. The greater cross – sectional area which was attached at the joining Aluminum and Glass Fiber Reinforced Epoxy shows the highest result of tensile strength resistance. As the conclusion, the investigation result shown the Specimen Design 1 is the best design which is having highest value of Ultimate Tensile Strength, highest maximum loading force and higher shear stress. This is the significance shown the highest resistance volume of joining profile may increase the Ultimate Tensile Strength, increase the value to absorbing force and more difficult to failure.
