The revolution in the global market of composite materials is evidenced by their increasing use in such segments as the transport, aviation, and wind industries. The innovative aspect of this research is the methodology approach, based on the simultaneous analysis of mechanical and tribological loads of composite materials, which are intended for practical use in the construction of aviation parts. Simultaneously, the methodology allows the composition of the composites used in aviation to be optimized. Therefore, the presented tests show the undefined properties of the new material, which are necessary for verification at the application stage. They are also a starting point for further research planned by the authors related to the improvement of the tribological properties of this material. In this article, the selected mechanical and tribological properties of an aviation polymer composite are investigated with the matrix of L285-cured hardener H286 and six reinforcement layers of carbon fabric GG 280P/T. The structure of a polymer composite has a significant influence on its mechanical properties; thus, a tribological analysis in the context of abrasive wear in reciprocating the movement for the specified polymer composite was performed. Moreover, the research was expanded to dynamic analysis for the discussed composite. This is crucial knowledge of material dynamics in the context of aviation design for the conditions of resonance vibrations. For this reason, experimental dynamical investigations were performed to determine the basic resonance of the material and its dynamics behavior response. The research confirmed the assumed hypotheses related to the abrasive wear process for the newly developed material, as well as reporting an empirical evaluation of the dependencies of the resonance zone from the fabric orientation sets.

“…The external forcing influence over harvesters energetic performance and dynamic characteristics have also been widely investigated in [4,29,31,35], which consider mixed harmonic and random noise forcing, and also in [3,12], that explore the possibility of energy scavenging in a quasi-periodic regime from a delayed dynamics. The multidisciplinary character of the theme also motivates the extension of the discussion to the coupled electrical circuits, as seen on [2,6,24,38].…”

-In the paper the magnetostrictive (MsM) cantilever beam model was analysed. The MsM material was taken into account as Galfenol, the alloy including the Gallium and the Ferrum. The burdened beam system via external excitation produces the magnetic field due to created maximal stress on the external beam fibres. By applied the external coil subsystem, the electrical energy was captured. The main goal of the analysis was to investigate the influence of the beam neutral axis position for energy harvesting efficiency. In case, the neutral axis agrees with the symmetry axis of the magnetostrictive beam, the magnetic fields cancel each other out, while stress is on. This effect disappears while the neutral axis is moved beyond the MsM beam's symmetry. It was estimated the influence of the beam response vibration amplitude on the output electric energy extracted from the system, at increased an effective MsM layer. It was analysed in the vicinity of the first resonance frequency, where the output voltage reached the maximum values.
