Human society’s need to build low-weight, high-strength and durable structures has increased the demand for composite materials. In this case, composites are used where high mechanical strength, low weight, sound thermal insulation properties required. One of most important issues now is designing materials coatings aimed at reducing heat loss resisting temperatures. way address problem develop...

This work discusses the mechanical and dissipative properties of nanocomposite materials made a high-performance thermoplastic polymer (polybutylene terephthalate, PBT) integrated with branched carbon nanotubes (bCNTs) as nanofiller. The storage loss moduli well factor/damping ratio nanocomposites are experimentally characterized for increasing bCNT weight fractions (wt% bCNT) upon variations i...

Introduction: Carbon nanotubes (CNTs) are ideal reinforcing fillers for a polymer matrix, because of their nanometer size, high aspect ratio and, more importantly, their excellent mechanical strength, and electrical and thermal conductivity. The CNTs are categorized into two groups: SWCNT and MWCNT. MWCNTs would have diameters ranging from 2 to 100 nm and lengths of up to tens ...

excellent mechanical properties of carbon nanotubes (cnts) make them outstanding candidate reinforcements to enhance mechanical properties of conventional composites. the glass/polyester composites are widely used in many industries and applications. improving the mechanical properties of such composites with addition of cnts can increase their applications. in this research, multi-walled carbo...

This article presents the buckling behavior of carbon nanotubes reinforced sandwich-structured composite shells supported by elastic foundations. The configuration is composed three layers, an isotropic core, and two nanocomposite face sheets. Carbon fibers are applied to reinforce sheets sandwich shells. It assumed that distribution reinforcements across shell thickness uniform or functionally...

background: osteoarthritis is one of the most common diseases in middle‑aged populations in the world and could become the fourth principal cause of disability by the year 2020. one of the critical properties for cartilage tissue engineering (te) is the ability of scaffolds to closely mimic the extracellular matrix and bond to the host tissue. therefore, te has been presented as a technique to ...

The introduction of new materials and processes to microfabrication has, in large part, enabled many important advances in microsystems, lab-on-a-chip devices, and their applications. In particular, capabilities for cost-effective fabrication of polymer microstructures were transformed by the advent of soft lithography and other micromolding techniques (1, 2), and this led a revolution in appl...

in this research, the buckling and bending behaviour of smart nanocomposite plate reinforced by single- walled carbon nanotubes (swcnts) under electro-magneto-mechanical loadings is studied. the extended mixture rule approach is used to determine the elastic properties of nanocomposite plate. equilibrium equations of smart nanocomposite plate are derived using the hamilton’s principle based on ...

Abstract Two-dimensional (2D) molybdenum disulfide (MoS 2 ) has been recognized as a potential substitution of platinum (Pt) for electrochemical hydrogen evolution reaction (HER). However, the broad adoption MoS is hindered by its limited number active sites and low inherent electrical conductivity. In this work, we employed one-step solvothermal synthesis technique to construct ternary hybrid ...

Epoxy is extensively used for anti-corrosion coatings on metallic materials. Conventional epoxy have a permanent crosslink network that unable to repair itself when cracks and damages occur the coating layer. This study aims develop self-healing vitrimer/carbon nanotube (CNTs) nanocomposite coating. Two bio-based curing agents viz., cashew nut shell liquid (CNSL) citric acid (CA) were employed ...
