| description | The high efficiency and low cost repair of perforation damage of aluminum honeycomb sandwich structure is of great significance to ensure the integrity of aviation equipment. A composite carbon fiber wet patch bonding repair process is proposed for metal panels with perforated damage in aluminum honeycomb sandwich structures. Combined with typical aluminum honeycomb sandwich structures in aircraft, intact and perforated damage samples are prepared, and composite bonding repair is carried out on perforated damage samples. A finite element simulation analysis model for four point bending strength analysis of aluminum honeycomb sandwich structure after patching and bonding repair is established, and the influence of perforation damage size on the four point bending strength of aluminum honeycomb sandwich structure and the strength recovery after repair are analyzed through simulation calculation. The results show that the bending strength of aluminum honeycomb sandwich structure can be effectively restored by using composite materials bonding method. The results of finite element simulation are in good agreement with the experimental results. The simulation model can accurately calculate the ultimate load and failure mode of all kinds of samples. The simulation results show that when the damage range is ≤<i>φ</i>30 mm (diameter to width ratio is less than 40%),the adhesive repair technology of composite materials can be applied to the damage repair of aluminum honeycomb sandwich structures of aircraft. |
