Abstract: Adhesives are widely used in many different areas such as aerospace, automotive and marine applications. Due to their low costs and mechanical advantages, adhesive joints have become preferable solutions. However, strength of these type of joints may vary with manufacturing process. In this study, adhesive thickness and surface roughness which are major factors that affect joint strengths were investigated. Uniaxial tensile and shear tests were performed for determining failure loads. Both tests were carried out in accordance with ASTM standards. Tensile tests have been performed for three different surface roughness and three different adhesive thickness. For tensile test specimens, a modification was done to curing mold in order to eliminate alignment problem between clamping jaws of test machine. In that way, scatter in test results were reduced. Standard thick adherend shear test (TAST) specimens were used for shear tests and only surface roughness effect was investigated. Test results showed the relation between joint strength and mentioned factors.
