This paper presents an experiment testing the damped free vibration of a system composed magnetorheological elastomer and mass. The goal this was to obtain dependence natural frequency damping ratio structure on applied magnetic field. shear properties, including storage modulus factor, were therefore determined. experimental results revealed that could reach value 60% zero-field dominated by field, but change in factor be neglected. Furthermore, when field moderate saturation did not occur,...
A state-of-the-art review is presented regarding the research and development of in situ fibre optic damage detection assessment systems (FODDAS) embedded fibre-reinforced composite structures. Representative individual strain sensors distributed sensor networks are briefly described. major emphasis placed on their capabilities for detecting damage, determining location assessing nature arising primarily from specific events such as impacts or quasi-static stress overloads. The main features...
Magnetorheological elastomer (MRE) is a new class of smart materials, whose modulus can be controlled by the applied magnetic field. In this paper, using white light speckle technique for deformation analysis, we present real-time dynamic progress (the vector diagram displacement or whole-field quantitative distribution) MRE and elastomer?ferromagnet composite (EFC) while field turned on. The experimental results verify prediction presented in recently published (Borcea Bruno 2001...
The nuclear industry strives to reduce the fuel cycle cost, enhance flexibility and improve reliability of operation. This can be done by both increasing weight optimizing rod internal properties that affect operational margins. Further, there is focus on reducing consequences failures. To meet these demands Westinghouse has developed ADOPT (Advanced Doped Pellet Technology) UO2 containing additions chromium aluminium oxides. paper presents results from extensive investigation program which...
Conventional epoxy thermosets, with irreversible crosslinking networks, cannot be reprocessed and recycled. Furthermore, the utilization of petroleum-based materials accelerates depletion non-renewable resources. The introduction dynamic covalent bonds use bio-based for thermosets can effectively address above issues. Herein, a series vitrimers imine were synthesized via simple solvent-free, one-pot method using vanillin-derived aldehyde monomers, 4,4-diaminodiphenylsulfone (DDS) bisphenol F...
The lack of an in-depth understanding electrical conduction behaviour in anisotropic carbon fibre-reinforced laminates was reflected by the fact that there no measurement standard. Various ad hoc experimental techniques were used, involving a range extrinsic parameters with little or rigorous control. Not only widely varying values conductivity, if not incorrect values, generated, but also effects attributed erroneously to those intrinsic parameters. This predicament compounded different...
The field-dependent dynamic flexural rigidity of a simply supported sandwich beam with soft core composed magnetorheological elastomer (MRE) part and non-MRE parts is studied in this paper. skins the are nonconductive such that there no magnetoelastic loads applied to during vibration. orientation chain-like structures inside MRE perpendicular operates shear mode. Due configuration, can be controlled by magnetic fields due modulus part. Based on Hamilton principle, model proposed developed....
China is a significant global producer and consumer of pesticides antibiotics, with their excessive use leading to substantial water pollution that poses challenges for subsequent treatment. Photocatalytic degradation, leveraging renewable solar energy, presents an effective approach decomposing organic pollutants reducing residual contaminant levels in bodies. This represents one way addressing environmental challenges. paper classifies representative photocatalytic materials by structural...
To develop high-performance epoxy resins (EP) that can be used to produce aircraft primary structure composite parts via vacuum-assisted resin infusion technology (VARI), low viscosity and high fracture toughness requirements must met as well maintaining the usual thermomechanical properties. Polymeric core/shell nanoparticles have demonstrated effectiveness in achieving these objectives, but their use at level causes reduction of composites' glass transition temperature modulus. By...
Damage characteristics of composite-skinned honeycomb sandwich panels in bending are investigated with both hemispherical (HS) and flat-ended (FE) indenters. The thickness the cross-ply skins varies from 8 to 16 plies, whereas density 12.7-mm thick aluminum core 50 70 kg/m 3 . Clamped a 100-mm testing area loaded quasi-statically either or on rigid base. effects varying these parameters damage mechanisms examined through response curves as well cross sections selected specimens. Special...
Abstract In this study, high‐performance thermoset polymer composites are synthesized by using both long fibers and nanoclays. Epoxy phenolic resins, the two most important polymers, used as matrix. The hydrophobic epoxy resin is mixed with surface modified nanoclay, while hydrophilic unmodified raw nanoclay to form nanocomposites. Long carbon also added into nanocomposites produce hybrid composites. Mechanical thermal properties of compared long‐fiber‐reinforced polymer‐ layered silicate...
Honeycomb sandwich panels of various skin thicknesses and core densities have been investigated under quasi-static loading in bending indentation with both hemispherical (HS) flat-ended (FE) indenters. Core crushing, top delamination, fracture are identified as major damage mechanisms. Their characteristics energy-absorbing capabilities established using load—displacement load—strain curves inspections cross-sectioned specimens. The effects varying thickness, density type, indenter nose...
