Composite nanofibers composed of polyacrylonitrile (PAN)-based carbon nanofibers and bioactive glass (BG) nanoparticles have been prepared by electrospinning and in situ sintering. Morphology observation showed that the BG nanoparticles of size 20-50 nm were uniformly distributed on the surface of composite nanofibers with 350 nm average diameter after carbonization. Biological mineralization i...

In this paper, free vibration analysis of carbon nanotube (CNT) reinforced laminated composite panels is presented. Three types of panels such as flat, concave and convex are considered for study. Numerical simulation is carried out using commercially available finite element analysis software ANSYS. Numerical homogenization is employed to calculate the effective elastic properties of randomly ...

The vapor deposition of open-networked carbon nanostructures and carbon nanotubes (CNTs)-reinforced composites have been developed and studied parametrically. Carbon nanostructures, including nano-tubes, nano-foams, nanoparticles, and nano-walls, have been deposited on catalyst-assisted substrates using microwave plasma electron cyclotron resonance-chemical vapor deposition (ECR-CVD) system at ...

In order to fabricate the composite electrodes of a supercapacitor, transition-metal oxide materials NiO and WO3 were deposited on carbon electrodes by electron beam evaporation. The influences of various transition-metal oxides, scan rates of cyclic voltammograms (CVs), and galvanostatic charge/discharge tests on the characteristics of supercapacitor were studied. The charge/discharge efficien...

A wide range of composite material forms are finding use in today’s aerospace, automotive, and other transportation industry segments. The Boeing 787 commercial airliner, unveiled in 2007, features over 50% carbon fiber composites by structural weight, while the entire structure of the Lamborghini Sesto Elemento supercar, unveiled in 2011, is made exclusively from carbon fiber composites [1-2]....

Carbon nanotube-cadmium selenide (CNT-CdSe) composite was synthesized by a facile hydrothermal method derived from multi-walled carbon nanotubes as a stating material. The as-prepared products were characterized by X-ray diffraction, scanning electron microscopy with energy dispersive X-ray analysis, transmission electron microscopy (TEM), and UV-vis diffuse reflectance spectrophotometer. The a...

Our paper reviews the use of conductive polymer composite materials in various applications for semi conductive, static-dissipative, anti-corrosive, electromagnetic interference (EMI) shielding and stealth composite coatings. The composite consists of conductive fillers and the insulating polymer network. The composite becomes electrically conductive as the filler content exceeds a certain crit...

A vanadium oxide-carbon nanotube composite was prepared by solution-based hydrolysis of NH4VO3 in the presence of carbon nanotubes. The carbon nanotubes induce the nucleation of the 1D vanadium oxide nanostructures, with the nuclei growing into long freestanding nanorods. The vanadium oxide nanorods with the lengths up to 20 μm and the widths of 5–15 nm exhibit a well-ordered crystalline struct...

Highly conductive fillers have a strong influence on improving the poor out of plane thermal conductivity of carbon fiber reinforced composites. The objective of this study has been to investigate the role of the diamond powder (DP) in enhancing the out-of-plane thermal conductivity of the woven composites. Samples of the standard modulus T300 carbon fiber composite with 44% and 55% fiber volum...
