“…Other nano-fillers appropriate for ablative composites can be surface-treated montmorillonitenanoclays, carbon nanofibers, nanosilicon carbide whiskers, halloysite nanotubes, nano-graphene platelets, perovskite compounds, nanosilica, nanoalumina, polyhedral oligomericsilsesquioxane, and nanosilicon carbide particles [ 10 , 13 ]. Recently, a study was conducted to explore the influence of multi-walled carbon nanotubes (MWCNTs) on the ablative performance of CFRE-Cs [ 14 ]. Scanning electron microscopy (SEM) images and the thermal conductivity analysis of pre- and post-burnt samples with thermogravimetric analysis (TGA) and oxyacetylene flame displayed that MWCNTs in the matrix amplified its thermal conductivity, which enhanced the erosion resistance.…”

The influence of nanodiamonds (NDs) on the thermal and ablative performance of carbon-fiber-reinforced–epoxy matrix compositeswas explored. The ablative response of the composites with 0.2 wt% and 0.4 wt% NDs was studied through pre-and post-burning morphologies of the composite surfaces by evaluation of temperature profiles, weight loss, and erosion rate. Composites containing 0.2 wt% NDs displayed a 10.5% rise in erosion resistance, whereas composites containing 0.4 wt% NDs exhibited a 12.6% enhancement in erosion resistance compared to neat carbon fiber–epoxy composites. A similar trend was witnessed in the thermal conductivity of composites. Incorporation of composites with 0.2 wt% and 0.4 wt% NDs brought about an increase of 37 wt% and 52 wt%, respectively. The current study is valuable for the employment of NDs in carbon fiber composite applications where improved erosion resistance is necessary.

“…Dongxian Zhuo et al prepared MWCNT/GNP membranes reinforced CFRP composites and the results showed that the incorporation of the hierarchical MWCNT/GNP membrane with 7.5 wt % of GNP displayed a 35% reduction in the peak heat release rate (PHRR) for a CFRP composite plate with the epoxy as matrix and an 11% reduction in PHRR [15]. Muhammad et al found composites containing 0.4 wt % MWCNTs showed a 9.6% increase in erosion resistance compared with the carbon fiber epoxy matrix composites, and thermal conductivity increased 52% with the addition of 0.4 wt % MWCNTs [16]. Hesami et al prepared MMT and APP modified GF/EP/CNTs composites to enhance its flame retardant properties, and the results showed that the combination of 0.5 wt % CNTs with 5 wt % MMT can increase the initial thermal decomposition temperature up to 62 • C; the addition of APP and CNTs together could increase LOI about 8% [17].…”

In order to study the effect of carbon nanotubes (CNTs) on the flame retardancy of carbon fiber (CF)/epoxy resin (EP) composites, CF/EP and CNTs/CF/EP composites were prepared by solution blending. The flame retardancy and thermal stability were studied by cone calorimetry and thermogravimetric analysis. It was found that CNTs and CF had a certain synergistic effect on improving flame retardancy and thermal stability of EP. The peak heat release rate of F7N7, which represents the EP composites with 0.7 wt % CF and 0.7 wt % CNTs, was minimal. The total smoke production of F5N5 which represents the EP composites with 0.5 wt % CF and 0.5 wt % CNTs was the smallest, which was decreased by 43.04% more than the EP. The initial decomposition temperature of F7N7 was about 14 °C higher than that of F7, and the mass loss at Tmax was greatly reduced. The apparent activation energy of F7N7 is 2.7 kJ·mol−1 more than EP. Finally, the tensile and flexural strength of the composites were also improved, so it could be applied to a high-performance matrix of CF/EP composites, which are usually used as the advanced composites in the aerospace field.

“…In addition, tube-tube interactions reduce the phonon mean free path of SWCNTs (−0.5–1.5 µm), and as such, the thermal conductivity value for SWCNTs is lower [178]. However, the phonon mean free path (20–500 nm) estimated for MWCNTs is much smaller than that for SWCNTs; thus, the phonon mean free path of MWCNTs in the alumina matrix is not affected by tube–tube interactions [134,179,180]. The main factors responsible for the marginal enhancement of the thermal conductivity of Al 2 O 3 -CNT nanocomposites include the scattering of phonons by residual pores, the tube–tube interactions of CNTs, the blocking of phonons by kinks or twists in agglomerated CNTs, the scattering of phonons by the interfacial resistance and high-temperature scattering due to increasing crystal vibrations.…”

An alumina-based nanocomposite is fabricated through the addition of secondary nanophase material to an alumina matrix to alter and tailor the properties of alumina. The addition to alumina of semi-conductive materials, such as silicon carbide (SiC), and high conductive materials, such as carbon nanotubes with a characteristic size in the nanometer range, can alter the mechanical strength, hardness, toughness, and electrical and thermal properties of alumina. This paper discusses recent advances in the synthesis of alumina–SiC and alumina-carbon nanotube (CNT) nanopowders and their consolidation using conventional and non-conventional techniques. Mechanical (hardness, fracture toughness and flexural strength) and functional (thermal and electrical) properties are discussed. The influence of the microstructure on the properties of alumina–SiC and alumina–CNT nanocomposites is discussed. Furthermore, potential applications and current related research trends are described.
