Abstract：In order to improve the bonding quality of composite materials for sports equipment，the bonding process of carbon fiber/aluminum plate glued joints was optimized by orthogonal test method，and the fracture morphology was observed.The results showed that the optimal ultrasonic vibration bonding process parameters of carbon fiber/aluminum plate glued joints were as follows： vibration position 25 mm，vibration amplitude 60μm ， vibration pressure 0.5 MPa，and vibration time 25s.The fracture load and bonding strength ofthe carbon/aluminum plate bonding joint were significantly improved after orthogonal optimization compared with those without vibration，and the fractureloadand bonding strength of thecarbon/aluminum plate bonding jointundertheorthogonaloptimizationprocess were 142.13% and 141.59% of those of the carbon/aluminum plate bonding joint under the non-vibration process ， respectively. Defects such as cracks and small holes could be seen between the adhesive layer and the carbon fiber plate at the section of theadhesive layer of the carbon fiber/aluminum plate adhesive joint without vibration，while the connection between the adhesive layerand the carbon fiber plate at the section oftheorthogonallyoptimized carbon fiber/aluminum plate adhesive joint for sports equipment was relatively tight，and no obvious cracks，holes and other defects were found，and the adhesive quality was good.
