“…CNFs, as well as the multiwalled nanotubes (MWNTs) and the singlewalled nanotubes (SWNTs), are the most common components of the nanocomposites [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Industrial products made of reinforced polymers demand improvement of the mechanical properties to preserve the structural integrity and the electrical conductivity to dissipate static electricity [16].…”

Carbon nanohybrid material (CNF/ -Fe 2 O 3 ) was obtained via a modified sol-gel technique consisting of two steps: functionalization of carbon nanofibers (CNF) in H 2 SO 4 /HNO 3 followed by synthesis using Fe(NO 3 ) 3 •9H 2 O. As a result, the iron content of the CNF/ -Fe 2 O 3 was increased by more than twice from about 40% to about 87% mass percent, compared to the pristine CNF and oxidized CNF specimens, as proved by energy dispersive X-ray fluorescence. Scanning electron microscopy images exhibited "cumulus" on the CNF/ -Fe 2 O 3 specimen surface, which showed the highest iron mass percentage, proved by energy dispersive X-ray spectroscopy. Transmission electron microscopy images confirmed attachment of -Fe 2 O 3 cumulus to the inner and outer surfaces of the CNF walls after synthesis. The characteristic peaks of Fe 2p 3/2 and Fe 2p 1/2 appeared in the XPS spectra obtained on CNF/ -Fe 2 O 3 . In addition, X-ray diffraction (XRD) results indicated formation of -Fe 2 O 3 during the synthesis process. The Raman spectrum of the CNF/ -Fe 2 O 3 sample displays peaks with positions close to characteristic peaks of highly crystalline and monodisperse maghemite nanocrystallites. The synthesis of CNF/ -Fe 2 O 3 leads to an increase in the hydrophilicity of CNF and magnetic properties at room temperature.

Flywheel Energy Storage for Automotive Applications

et al. 2015

A review of flywheel energy storage technology was made, with a special focus on the progress in automotive applications. We found that there are at least 26 university research groups and 27 companies contributing to flywheel technology development. Flywheels are seen to excel in high-power applications, placing them closer in functionality to supercapacitors than to batteries. Examples of flywheels optimized for vehicular applications were found with a specific power of 5.5 kW/kg and a specific energy of 3.5 Wh/kg. Another flywheel system had 3.15 kW/kg and 6.4 Wh/kg, which can be compared to a state-of-the-art supercapacitor vehicular system with 1.7 kW/kg and 2.3 Wh/kg, respectively. Flywheel energy storage is reaching maturity, with 500 flywheel power buffer systems being deployed for London buses (resulting in fuel savings of over 20%), 400 flywheels in operation for grid frequency regulation and many hundreds more installed for uninterruptible power supply (UPS) applications. The industry estimates the mass-production cost of a specific consumer-car flywheel system to be 2000 USD. For regular cars, this system has been shown to save 35% fuel in the U.S. Federal Test Procedure (FTP) drive cycle.

“…Resistance welding technology has been developed for CFRTP, and the further improvement of bond strength is needed to reduce the bonding area. Carbon nanotube (CNT) is expected to be used as additive because of its remarkable physical, thermal and electric properties [4], [5]. Grafting CNT on the surface of carbon fibers was reported to improve the fiber matrix interfacial shear strength [6] and the resistance welding in which carbon fiber was used for heating elements was reported to increase bond strength [7].…”

Carbon Nanotube (CNT) grafted carbon fibers were used for the heating element of resistance welding, and the effect of CNT deposition time at deposition temperature of 600ºC on the tensile lap-shear strength of resistance welded CFRTP was evaluated. The longer the deposition time became, the longer the length of CNT became. The highest tensile lap-shear strength was obtained when CNT grafted carbon fibers grafted at the deposition time of 30 minutes were used for the heating element of resistance welding because it is reported that fiber matrix interfacial properties of the carbon fiber was improved by CNT deposition to the surface of carbon fiber. In the case of the CNT grafted carbon fibers grafted at the deposition time of 60 minutes, lower tensile lap-shear strength was obtained because of the poor impregnation of the resin into the carbon fiber due to the excess CNT on the carbon fibers. The length of CNT should be controlled to obtain good mechanical properties.
