“…High thermal conductivity is necessary to achieve good performance of thermal dissipation when CNT conductors are subject to high current density. Theoretically, CNT fibers and films have great potential applications in thermal management, flexible heating, or batteries . The thermal conductivity of CNT fibers at room temperature was reported with a value of (60 ± 20) W m −1 K −1 .…”

and environmentally friendly conductive cables or wires as a replacement for copper. From this view, carbon-based nanomaterial is a potential candidate.Carbon related nanomaterials including fullerenes, carbon nanotubes (CNTs), and graphene are promising due to their exceptional conductive and electronic transport properties, which may accelerate the practical and potential applications for various kinds of novel engineering areas spanning from electronics, energy storage, and advanced materials to nanotechnology and biotechnology. Among the family of carbon nanomaterials, CNTs have been a particularly attractive material since its discovery in 1991 by Iijima, [1] due to their nanoscale 1D shape, excellent mechanical properties, tunable electrical properties either metallic or semiconducting, high current carrying capacity, and many other exciting properties. These properties have highlighted the potential of CNTs use in a plethora of applications, including electrically conductive fillers in polymer composites, flexible and transparent conductive films, microelectronics (transistors, interconnectors, heat dissipaters), and lightweight conducting wires and cables. [2] Figure 1 points out the forecast presented by Endo et al. [3] on the present, near future, and long term applications of CNTs in various fields. An interesting potential application of CNTs is the long-term electrical conductors, which are able to transmit power from plants to plants or households, as well as be used in electronic devices.Compared to conventional copper cables or wires, CNT based cables have several advantages including 1) a lower density of 1.3 g cm −3 for single-walled carbon nanotubes (SWCNTs) [4] and 2.1 g cm −3 for multiwalled carbon nanotubes (MWCNTs), [5] both of which are much lower than that of copper, 8.96 g cm −3 ; [6] 2) environmental stability, which can stand with severe conditions including high pressure, large temperature changes, etc.; 3) excellent mechanical performance with a Young's modulus and strength in the ranges of 1.0 TPa and 50 GPa, respectively; [7] 4) ultrahigh electrical conductivity as high as 10 8 S m −1 for SWCNTs, which is higher than that of copper (≈10 7 S m −1 )). [8] Furthermore, the limited amount of conventional conductive metal resources in nature and their soaring market price greatly increased the need for a desirable alternative solution that are abundant in nature, low-cost, andThe lack of progress to obtain commercially available large-scale production of continuous carbon nanotube (CNT) fibers has provided the motivation for researchers to develop high-performance bulk CNT assemblies that could more effectively transfer the superb mechanical, electrical, and other excellent properties of individual CNTs. These wire-like bulk assemblies of CNTs have demonstrated the potential for being used as electrical conductors to replace conventional conductive materials, such as copper and aluminum. CNT conductors are extremely lightweight, corrosive-resistive, and mechanically strong while being ...

“…By mounting the electrodes at both ends of the prepreg patches, the electrical current passes through the carbon fiber to produce the joule heat, and eventually the CFRPs patches are cured by the joule heat generated by themselves. In the past literature, SRE heating has been used in the processes of CFRPs curing 28–35 and composites joints bonding. 36,37 The results showed that SRE heating not only significantly reduced energy consumption, and shortened the curing cycle, but also achieved a preferable curing quality.…”

Carbon fiber reinforced plastics have been widely applied in aircraft structures, which require more rapidly repairing process when carbon fiber reinforced plastics structures are damaged. A novel method of self-resistive electrical heating to rapidly repair carbon fiber reinforced plastics parts was investigated, which utilizes the electrical current passing through the carbon fiber to generate heat and directly cure the whole carbon fiber reinforced plastics patches. A portable self-resistive electrical repairer with automatic temperature control unit was developed. Repair experiments of self-resistive electrical and the electrical blanket heating were conducted, in which the heating temperature distribution field was observed by the thermal infrared imager. The degree of cure of different samples was characterized, and the cross-section morphology and void content of different samples were assessed. Flexural and inter-laminar shear tests were carried out. The experiment results showed that the flexural and interlaminar shear strength recovery ratio of self-resistive electrical repaired samples attained to 85.48% and 65.89%, which was the same or even slightly higher level as the blanket repairing process, but only cost 62% repairing period and 58% repairing energy of the later one. Finally, from the experimental results, the heat transfer behavior of different processes was analyzed.

“…[10][11][12][13] Fabricating CNT bers with high conductivities has been studied extensively by many researchers due to the ease of effectively eliminating those drawbacks in ber forms [14][15][16][17][18][19] compared to CNT lms. [20][21][22][23] Different ways to spin CNT bers include from solution, 24 arrays, 18 aerogels, 8 and rolling CNT lms. 25 Following ber spinning, certain post-treatment methods are available to further increase conductivity.…”
