The performance of the adhesively bonded joints is affected by many environmental factors including the sunlight exposure. To evaluate the resistance to the sunlight, the adhesive material is assessed through standard mechanical tests including three points bending (3PBT) test after been exposed to different sunlight (Ultra Violet- UV) exposure level and time. In this investigation, accelerating weatherometer chamber is programmed to deliver two different ultra-violet levels and three intervals of exposure to simulate modified ultra-violet dosages based on Melbourne-Australia UV level conditions. Then 3PBT conducted. Test result shows noticeable change in the load carrying capacity of the beam in addition to a ductile behaviour in the fracture modes when increasing the UV dosage and exposure time. Post-failure and surface analyses showed significant change in colour and less change in the surface roughness. It is concluded that the UV exposure time has irreversible influence on the adhesive material, while the UV level has more influence than the exposure time.
