| Abstract Scope |
Thermoplastic composites and aluminum alloys are widely used in industries such as aerospace and automotive. However, reliably joining these dissimilar materials remains challenging. This study investigates the adhesive bonding of short-carbon-fiber-reinforced polyphthalamide (CFRPPA) to AA6061, in which the CFRPPA was plasma-treated and the AA6061 was laser-textured to create deep grooves. The hybrid plasma–laser treatment noticeably improved the lap-shear performance compared with the untreated, laser-textured-only, and plasma-treated-only baseline configurations. To further improve adhesive distribution within the deep laser-textured grooves, ultrasonic vibration was applied to promote more uniform spreading of the adhesive between the AA6061 and CFRPPA adherends. This approach resulted in an additional improvement of approximately 30% in lap-shear performance compared with the corresponding configuration without ultrasonic vibration, and the underlying mechanisms for this improvement were further elucidated through experimental microscopy and computational modeling. |
