The revolution in the global market of composite materials is evidenced by their increasing use such segments as transport, aviation, and wind industries. innovative aspect this research methodology approach, based on simultaneous analysis mechanical tribological loads materials, which are intended for practical construction aviation parts. Simultaneously, allows composition composites used to be optimized. Therefore, presented tests show undefined properties new material, necessary...
Composite materials are widely used in the construction of means transport. Due to their low density and high stiffness, sandwich composites generate significant interest. The authors conducted static dynamic tests order determine effect core thickness on mechanical properties a composite. Particular attention was paid impact such composites. Herex Airex polymer foams different densities were as cores, whereas faces made up two layers fabrics: glass carbon. matrix base tested epoxy resin...
In this research, an analysis of polymer composite with the matrix L285-cured hardener H286 and six reinforcement layers carbon fabric GG 280 T was provided. It involved a comparison dynamical behavior responses for three cases structures in context presence mass share modifier. The samples addition physical modifier varying percentages were investigated by being subjected to dynamic tests specific parameters, i.e., constant excitation amplitude vibration frequency vicinity base resonance...
The aim of this study was to examine the impact weathering and thermal shocks on abrasive wear epoxy resin composites reinforced with carbon fabric that are commonly used in aviation. composite exposed degradation an apparatus simulating then subjected abrasion process, without presence water. controlled by checking weight loss as well visual inspection. research findings indicated a significant effect water process friction upon deterioration resistance regard dry friction. long-term rapid...
In order to check the possibility of using powder aerogel as an additive matrix polymer ablative composite, experimental tests material strength composite well tribological properties and Shore D hardness depending on amount dispersed phase in form were carried out. perform tests, prepared samples differing percentage addition temperature cross-linking before test. Based study, it can be concluded that use deteriorated mechanical relation base (without additive). As a result adding aerogel,...

Abstract The underwater glider is buoyancy-propelled Autonomous Underwater Vehicle (AUV). Their propulsion relies upon changing their buoyancy with internal pumping systems enabling them upward and downward motion. In the presented paper, forward gliding motions are generated by hydrodynamic lift forces exerted on a pair of hydroplanes attached to hull. characteristics were determined using Computational Fluid Dynamics (CFD). A 3D model was created for simulation flow behaviour in Baltic...
Abstract Five series of samples were prepared, each batch consisting 20 epoxy-resin items, CES R70 with H72 hardener and 4 types powder additives: montmorillonite (MMT), Expancell d25 Microsphere (microsphere), nanocarbon (NanoC) silicon carbide (SiC). All the additives added in quantities corresponding to 15% total volume share material.

The complex thermophysical property of temperature-sensitive paint (TSP) research is discussed. TSP used for visualization the surface temperature distribution in wind tunnel aerodynamic tests. purpose this was to provide reliable, experimental, data applied as a coating. As thin layers, investigation its final properties challenging and demands application non-standard procedures. At present, most measurements were performed on composite specimens deposed onto metallic film substrate or...
