“…16,17 Recently, carbon nano tube (CNT), silicon carbide (SiC) and silicon nitride (Si 3 N 4 ) whiskers have been grown on CF surfaces and have been observed to improve interface dominated mechanical properties 18 while simultaneously deteriorating the fiber dominated properties, because of the requirement of hightemperature synthesis treatment. [19][20][21] In addition, strong van der Waals force between CNTs makes them tend to agglomerate and collapse, which may limit their toughening mechanisms such as pull-out or bridging. 22 Recently, ZnO nanowirebased composites have gained attention due to their multifunctional properties, such as piezoelectricity.…”

“…They investigated the effect of the dispersion of CNTs on compression-after-impact (CAI) strength and electrical conductivity of samples. Han et al [19] compared the effects of halloysite nanotubes, CNTs, and silicon carbide whiskers on the mechanical properties of epoxy/CF composites. Islam et al [20] were added surface-modified MWCNTs and nanoclay to epoxy reinforced by CF composites.…”

In this study, epoxy hybrid nanocomposites reinforced by carbon fibers (CFs) were fabricated by a filament winding. To improve out-of-plane (transverse) mechanical properties, 0.5 and 1.0 Wt.% multi-walled carbon nanotubes (MWCNTs) were embedded into epoxy/CF composites. The MWCNTs were well dispersed into the epoxy resin without using any additives. The transverse mechanical properties of epoxy/MWCNT/CF hybrid nanocomposites were evaluated by the tensile test in the vertical direction to the CFs (90º tensile) and flexural tests. The fracture surfaces of composites were studied by scanning electron microscopy (SEM). The SEM observations showed that the bridging of the MWCNTs is one of the mechanisms of transverse mechanical properties enhancement in the epoxy/MWCNT/CF composites. The results of the 90º tensile test proved that the tensile strength and elongation at break of nanocomposite with 1.0 Wt.% MWCNTs improved up to 53% and 50% in comparison with epoxy/CF laminate composite, respectively. Furthermore, the flexural strength, secant modulus, and elongation of epoxy/1.0 Wt.% MWCNT/CF hybrid nanocomposite increased 15%, 7%, and 9% compared to epoxy/CF laminate composite, respectively.

“…[ 24 ] CFs grown with nanostructures on the surface, that is, nano‐whiskered CFs, not only maintain their inherent high strength, low resistivity, and high‐thermal conductivity, as well as being significantly enhanced in terms of mechanical properties and interfacial bonding properties. Various techniques, including chemical vapor deposition (CVD), [ 25 ] electrophoretic deposition (EPD), [ 26 ] microwave treatment, [ 27 ] and hydrothermal methods, [ 28 ] have been employed for the controlled growth of different nanostructures, such as nanosheets, [ 26 ] nanowires, [ 29 ] nanotubes, [ 30 ] and nanoflowers, [ 31 ] on the surface of CFs. After whiskerization, independent binder‐free composites with multiscale are formed by integrating the grown nanostructures with the CF substrate.…”

In the present study, the embedding ZnO nano‐whiskers (NWs) on carbon fiber (CF) surface was carried out to study the changes in Ohmic heating and mechanical stability of carbon fabric reinforced green epoxy composite laminates. The ZnO NWs were grown onto the CF surface by hydrothermal method and subsequently the laminate composites with different number of carbon woven layers were prepared. To study the resistive heating behavior of the laminate composites, the temperature versus time curves were analyzed in three sections, from which the temperature response rate, the maximum temperature, and the electrical power efficiency were estimated. Later, the effects of Ohmic heating action on the structural damage and mechanical stability of the composites were examined by dynamic mechanical analysis and X‐ray micro computerized tomography. Multilayer ZnO/carbon woven composites were found to be rapidly heating, less power consumption, and have improved mechanical and structural stability over bare carbon woven composites. This indicated that ZnO NWs enhanced the adhesion between the fibers and matrix, meanwhile acting as a heat barrier to avoid degradation of the epoxy at the interface of the fiber and matrix during Ohmic heating.
