    Análisis de la resistencia mecánica de la punta de ala WING TIP-FAIRING ASSY luego de ser reparada con materiales alternativos

    This investigation began with an evaluation of damage by visual inspection of all Wing Tip Fairing Assy components. It was necessary to consider the analysis of the codes for the inspection and reparation of aircrafts. For this, visual inspection reports were issued detailing each of the indications detected on the aerodynamic surfaces. Besides, the materials used in the reparation process follow the laminate configuration of the original components; copper, carbon fiber, kevlar, and fiberglass mesh, as well as a matrix of epoxy resin from the AEROPOXY brand. Furthermore, for the foundation of the restoration process, we based on the recommendation given by the manufacturer’s maintenance manuals, specifically in the parameters of step roughing, and conformed to the vacuum of the repair patches. The study of mechanical resistance of the repaired components was achieved with the application of the reflection essay in three points according to the NTE INEN 2047 standard. In addition, it helped to establish the tensile strength values, elasticity modulus, and the percentage elongation of composite materials. The results obtained were evaluated and analyzed based on FAA airworthiness parameters and previous research, these being the references that validate the repair procedure on Wing Tip Fairing Assy composed of alternative materials. Then, the repair process defined by staggered patches in an oval and vacuum shaped configuration is an effective method in the restoration of flight surfaces.
