The objective of this research is to characterize mechanical and physical behaviors of adhesives bonding (butt and lap joints) on mild carbon steel. The research used an adhesive material of devcon plastic steel. Mechanical properties are tensile strength, shear strength and toughness of the joints. The major parameters of this research were adherends surface roughness Ra, adhesive thickness, curing time and curing temperature. Surface roughness of the carbon steel adherends are Ra = 0,52 pm, 0,76 11/71 and 1,21 pin. Adhesive thickness vary from: 0,03 mm to 0,3 mm and curing time: 1, 2, 3, 4 hours at curing temperatures: 55, 70, 85, 100, 120 and 140 °C. The research has been conducted under static loads at room temperature. The results of ...
