dc.description.abstractGraphene is a recent material whose properties allow it to replace or complement other materials in various applications. Given its high rigidity, it opens the door for its use in aeronautical structures, which apart from having their mechanical properties improved, it also allows for weight reduction of such structures. The main objective of this work is to characterize laminated composite materials made of three different matrices, in order to evaluate the impact that graphene has on the mechanical properties of laminates. The implementation of graphene in aeronautical structures is also studied, specifically, in the design of a wing structure for a class I unmanned aerial vehicle (< 25 kg). Initially, tensile and bending tests were carried out with specimens manufactured with three different matrices: the matrix used at the Centro de Investigação da Academia da Força Aérea; the graphene-based matrix produced by Graphenest, S.A.; and the base matrix used in the production of the previous one, but without graphene. Tests were carried out with bidirectional and unidirectional carbon fibers until material failure occurred. Improvements of 6.2% in the modulus of elasticity between the graphene matrix and the first one were obtained. Finally, the obtained properties were implemented on the wing design, using finite element analysis. Linear static and linear buckling analyses were performed, and decreases of 0.6% to 6.2% in stress and 6.1% in displacement were obtained, when comparing the graphene-based matrix with the first one.por
