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.

Tensile tests were carried out on three series of composite samples according to the ASTM (American Society for testing and Materials). The materials tested were characterised by using the same manufacturing method. The specimens were hand-laminated using MGS L285/H285 epoxy resin. The feature that differentiates the structure of each laminate series is the type of reinforcement. A biaxial fabric IMS65 CtLX with a 0/90 arrangement was used to reinforce the C-series composite specimens; for the D-series, a symmetrical fabric Interglass 02037 with a 0/90 weave was used, and for the E-series specimens, a modular fabric IMS65 with a 45 weave was used. The share of composites in the manufacture of construction products is steadily increasing. This is due to the development of new technologies for manufacturing composite elements and composites, with properties that are more and more in line with the requirements of the industry resulting from technological progress. Composite products have to meet many performance requirements. Tensile testing is used to determine some of the key mechanical properties of laminates. Fibre-reinforced polymer (FRP) composites have been used in various engineering structures for many decades. Their unique physical and mechanical properties make them a well-known, most produced and most widely used type of composite materials. In the case of fibre composites, it is the fibres that take over the basic stresses and are responsible for achieving the appropriate stiffness and strength, while the matrix ensures optimum use of the properties of the fibres and gives shape to the manufactured element. The mechanical properties of the composite and its failure process are fundamentally dependent on the high strength of the fibres, the stiffness of the matrix and the strength of the fibre-matrix interface.

“…Epoxy resin matrix composites are widely used in glider construction, but have not been used for heavily loaded aircraft structural components due to the low stiffness of glass fibres. The appearance of high-strength and highstiffness boron and carbon fibres gave a chance to use polymer composites to make entire structural elements as well as to reinforce elements of airframe which were made of metals [13]. At present, it is possible to make integral covers of several metres in length, including stiffening elements.…”

The paper presents a study on infl uence of diff erent fabric weave and fabric orientation on strength properties of fi ber reinforced polymer composites. The research concerns materials used in a new type of rotorcraft. Four series of laminates were fabricated with hand forming, using the MGS L285/H285 epoxy resin. Triple-kind experiments were performed: the Shore hardness measurements, tensile strength testing and fractographic analysis. The specimens of diff erent series shown various strength and stiff ness characteristics, depending on the type of weave and fabric layup. Three diff erent failure schemes were observed. The Poisson coeffi cient was diff erent among series, as well, but no understandable link to specimen morphology could be found so far. Fractographic observations suggested intralaminar delamination.
