摘要：
Based on the non-contact ultrasonic testing method, the bonding quality of composite bonding structure is simulated and experimentally explored. Firstly, the time-domain simulation model of ultrasonic transmission characteristics of composite bonded structures is established, the frequency-domain transmission coefficient spectrum is extracted, and the effects of interface weakening and cohesion weakening on ultrasonic transmission characteristics of bonded structures are analyzed. At the same time, the spectrum of ultrasonic transmission coefficient in different bonding states is in good agreement with the calculation results of plane wave theory. In addition, fiber reinforced composite(FRP) bonding structures with different bonding interface states and adhesive layer cohesion weakening states were prepared. Based on the water immersion ultrasonic measurement system, the effects of different bonding interface states and cohesion weakening states on the ultrasonic transmission coefficient spectrum are experimentally investigated. The relationship between the ultrasonic transmission characteristics in the bonding structure and the bonding quality is analyzed, which is consistent with the simulation results. In addition, according to the mapping relationship between bonding quality and ultrasonic transmission characteristics in composite bonding structures, it also lays a solid foundation for nondestructive characterization and evaluation of composite bonding structures. © 2024 Chinese Mechanical Engineering Society.
