Carbon fiber reinforced plastic (CFRP) is increasingly considered for various industrial applications. CFRP has been applied to the automotive industry to increase fuel efficiency due to its excellent strength and lightweight. Therefore, the demand for dissimilar material joining techniques is gradually increasing. In this study, we investigated the intense pulsed light (IPL) as surface treatment for CFRP. The IPL surface treatment requires a very short processing time and can be easily automated compared with other processes such as chemical and mechanical treatments. The change in morphology and chemical composition of the CFRP-treated surfaces was analyzed using scanning electron microscopy, profiler, and X-ray photoelectron spectroscopy. The bonding strength due to varying IPL exposure time was evaluated by the lap shear test. The apparent shear strength increased by up to 159% in this study. The IPL treatment is very simple and requires short processing time to produce enhanced adhesive joints. [ABSTRACT FROM AUTHOR]
