“…1-1-6912 [11]), which lacks a process that allows repeatability and further hinders the developments of new bonded repair techniques. Bonded repairs can involve bolted patch repair, adhesive bonded patch repair [12], scarf, and etc. A simulation study has shown that bolted patch repair and adhesive bonded patch repair can have different efficiencies and effectiveness [13].…”

Finite element simulations of bonded repair technology can greatly reduce the cost of repairing ageing and damaged aircraft structures. In this study, finite element simulation and analysis are performed for several bonded repair techniques of damaged aircraft structures with cracks. The simulations start from fatigue damage accumulation, crack initiation, crack repair, to fatigue crack re-initiation until structural failure. The effectiveness of bonded repair techniques is assessed by comparing the service lives of no repair, patch-bonded repair (live repair), stop-drill repair, and damage removal repair. It is found that the load attraction by repair patch can greatly sustain fatigue crack growth, leading to more than at least 2 times longer service life before the skin structure needs to be replaced. Damage removal bonded repair can further extend service life by more than 20 times comparing to no repair, benefiting from the fatigue damage tolerant service life extension. Along with the service life comparison, we also established a simulation framework that lays out the groundwork to perform aerostructure bonded repair effectiveness evaluation. The results demonstrate that finite element analysis can be efficiently used to simulate the various forms of bonded repairs and effectively evaluate fatigue crack growth and service life with structural damage. Such a rigorous simulation framework enables the future design of new repair techniques for aircraft structures.

“…With this type of adhesives, the curing time under pressure can be controlled not only through the quantity ratio but also with heat. There are also solid adhesive films that are thermally activated, which do not depend on the experience of the person mixing as in the case of glues with two components, eliminate glue waste, and the properties are which are guaranteed by the manufacturer [29,30].…”

Sandwich structures present several advantages, being used in many industries such as the aeronautical industry. In this study, an automated laminating line is employed to manufacture sandwich panels for boards. This work focus on an innovative solution, employing an advanced adhesive film to increase the bonding strength of sandwich structures used for this application. This was used to bond ceramic steel sheets to honeycomb‐cored structures, creating an innovative solution for the board industry. Bending tests were carried to evaluate the performance of the new sandwich solutions and to compare it against a typical one available on the market.
