Adhesive bonding is a novel structural connection method for composite and metal materials in the aerospace field. In this paper, a gluing and separating process for the bonded anchor nut is proposed. The anchor nut is bonded to the mounting plates made of aluminum alloy 7050-T7451, titanium alloy TC4-DT, and composite material ZT7H/5429. The ejection force, torque, and vibration of the installed anchor nut are tested. The vibration frequency is set at 30Hz, with an amplitude of 11.43±0.38mm, and the vibration cycle is set to 30,000, 40,000, and 50,000 times, respectively. After the vibration test, the nuts are heated to 150℃, 200℃, and 250℃, and retained for 35-45 seconds before removal. This research investigates the feasibility of the installation process of the bonded anchor nuts and its separation effect under different vibration cycle times and separation process parameters. The experimental results show that the installed anchor nuts meet the requirements of ejection force, torque, and vibration tests, which verifies the feasibility of the installation process. In the separation process, the proposed method is feasible for separating titanium alloys and composite materials. The surface of the aluminum alloy plate becomes coarser after sanding compared to other materials, resulting in better bonding strength and requiring a higher temperature for disengagement. This research provides fundamental theoretical data for bonding and separating anchor nuts on different material mounting plates.
