The aim of this study is to determine the effects of surface roughness, adhesive thickness and overlap distance on the joint strength in prismatic plug-in joints combined with adhesive. For this purpose, samples produced in three different types of overlap distance, three different types of adhesive thickness and three different types of surface roughness were attached by three different widely used epoxy-based adhesives, resulting in a total of 81 prismatic plug-in joints. The strength of each joint was determined by subjecting them to axial tensile tests and the results are presented as a comparison.


Key words: Adhesive, surface roughness, prismatic plug-in joint, joint strength.
