Abstract
The article presents a comparative characterization of the structural materials (composites and metals) used in modern aviation structures, focusing on the airframe structure of the most modern aircraft (Airbus A-380, Boeing B-787, and JSF F-35). Selected design and operational problems were analysed, with particular emphasis on composites and light metals (aluminium). For this purpose, the Shore’s method was used for the analysis of the obtained strength results and the programming environment (ANSYS, SolidWorks) required to simulate the GLARE 3 2/1-04 composite. The focus was on highlighting the differences in the construction and modelling of these materials resulting from their various structures (isotropy and anisotropy), e.g., by analyzing the mechanics of metal destruction and comparing it with the composite material. In terms of solving the problems of finite element analysis FEM, tests have been carried out on two samples made of an aluminium alloy and a fiberglass composite. The focus was on highlighting the differences in the construction and modelling of these materials resulting from their various structures (isotropy and anisotropy), e.g., by analyzing the mechanics of metal destruction and comparing it with the composite material. On the basis of the obtained results, the preferred variant was selected, in terms of displacements, stresses, and deformations. In the final part of the work, based on the conducted literature analysis and the conducted research (analysis, simulations, and tests), significant observations and final conclusions, reflected in practical applications, were formulated.
Highlights
In the currently evolving technical progress, one can increasingly see the use of composite materials, in the aspect of advanced design solutions of most modern aircraft (Airbus A-380, Boeing B-787, SJF F-35, unmanned aerial vehicles (UAVs))

The conducted research process of composite materials, used in their structure reinforcements in the form of polymer fibers, indicates that materials of this type require constant evaluation and further exploration in the field of more and more perfect and newer construction materials; in particular, those related to the issues of material strength, e.g., in terms of vibration damping, lightness, or resistance to external factors, which have had a key impact on their practical application in the aviation industry
Summary
In the currently evolving technical progress, one can increasingly see the use of composite materials, in the aspect of advanced design solutions of most modern aircraft (Airbus A-380, Boeing B-787, SJF F-35, UAV). The conducted research has shown that it is possible to develop a new metallopolymer composite based on modified epoxy matrices This composite is characterized by good strength properties, a low coefficient of friction, and high wear resistance. In the lifting elements, which include the wing sheathing, flaps, mer composite based on modified epoxy matrices This composite is characterized by vertical and horizontal stabilizers, and the fuselage, a fiber-reinforced laminate and a good strength properties, a low coefficient of friction, and high wear resistance. Mainly in aviation [5] Another example of the use of AFRP (aramid fiber reinforced polymer) composite materials is the American Boeing AH-64 Apache helicopter, in which composites were used to produce the main and tail rotor blades. The design of the Swedish multirole Saab JAS 39 Gripen is based on the use of both metals and carbon fiber composites [19,20,21]
