Conductive inks consisting of graphene and carbon black conductive fillers into a polydimethylsiloxane (PDMS) matrix, which can be processed thin films by screen printing are developed. The influence filler composition content on mechanical electrical properties the composites is investigated. best were evaluated as electrode material for dielectric elastomer actuators piezoelectric sensors. With increasing content, resulting graphite nanoplates (GNPs) or binary mixture GNPs (CB) with PDMS...
Controlling the grain size of steels is an effective way for tailoring their mechanical properties, such as yield strength, impact toughness, and ductility. In this study, a new industrial thermomechanical treatment was applied to low-alloyed TRIP-assisted bainitic steel 13MnSiCr7 achieve substantial microstructural refinement. average micro-bainitic decreased from ∼25 μm ∼5 μm. Fatigue tests were carried out in order investigate influence on crack propagation behavior. Besides electron...
Stretchable electrodes are more suitable for dielectric elastomer transducers (DET) the closer mechanical characteristics of and are. Here, a solvent-free synthesis processing conductive composites with excellent electrical properties presented. The prepared by in situ polymerization cyclosiloxane monomers presence graphene nanoplatelets. low viscosity monomer allows easy dispersion filler, eliminating need solvent. After polymerization, cross-linking agent is added at room temperature,...
Abstract Pultruded glass fiber–reinforced plastic (GFRP) rods are industrially produced for various applications. The mechanical properties of GFRP can be tailored, eg, with modified epoxy matrix by adding microsized and nanosized fillers. In this work, we investigated the transferability fracture nanocomposites to rods. For purpose, nanosilica particles, micron‐sized rubber, calcium carbonate were used as Firstly, plates different combinations fillers their toughness evaluated. Secondly,...
Glass-fiber reinforced polymer (GFRP) composite rods with epoxy matrix filled electrically nonconducting particles find widespread use in high-voltage electrical insulator applications. The service loads require a range of different, minimum material property values, e.g. toughness, tensile, or compressive strength, but also component-specific performance, pull-out friction surface crimped metal fittings electric breakdown strength. contribution discusses selected examples the effects...
This paper reviews the relevant literature and covers main aspects of environmentally assisted cracking Al-Mg-Si-(Cu) alloys. Apart from a brief overview major microstructural mechanical properties, it presents research results on corrosion sensitivity stress susceptibility Al-Mg-Si Possible mechanisms fatigue in aluminum alloys, such as anodic dissolution and/or interaction with hydrogen, are considered. A number factors, including atmospheric or solution conditions, applied stress,...
Additive manufacturing (AM) techniques have revolutionized the production of Ti6Al4V parts across various industries. However, widespread adoption AM is impeded by their inadequate fatigue performance, particularly in high cycle regimes. A significant contributing factor to this limitation presence internal defects inherent process, which act as sites for crack initiation. While previous investigations focused on performance alloys with gas porosities, research lack-of-fusions (LOFs),...
It was shown previously that cyclic loading can be used to extend the fatigue life of sheet plastic materials subjected preliminary impact-oscillatory loading. This type causes dynamic non-equilibrium processes (DNP) in materials, which lead formation dissipative structures and on their surface. The density these is less than base metal. In this paper, results investigations into relief hardness surface layers modified by are analyzed example five structural materials. signs a regular,...
Abstract Additive manufacturing techniques have made AM Ti-6Al-4V parts a reality in many industries. However, despite the optimism, their poor fatigue performance especially high cycle regime is major hurdle for industry accepting it as mainstream. One of reasons owes to widely distributed internal defects inherent process, which create hotbed crack initiation. Available investigations on lack fusions, regarded most detrimental defects, are very limited. Regarding this, we conducted finite...
