Structural Health Monitoring has become one of the next challenges in the aeronautical industry in order to know the real-time status of structures and optimize their maintenance. The use of Lamb Waves for damage detection is proven; however, its effectiveness is affected by the boundary conditions in which the structure is located. To counteract this effect, it is essential to model its behavior in different environmental and operating conditions to ensure the correct detection of variations in the structure during its service life. This work presents the characterization of the Lamb wave behavior for a composite UAV supporting surface. By applying different load and temperature conditions to the structure, different conditions of the structure during flight will be simulated. The results obtained for the newly fabricated structure will be compared with the results obtained for the same structure damaged by impact. And finally, the main effects produced on the signal (arrival time, amplitude...) will be analyzed; and how they can simulate the presence of a damage that has not occurred (false positive) or camouflage the presence of existing damage (false negative).
