“…In Al 2 O 3 matrix composites, carboxyl (COOH − ) adheres onto the surface of the CNT through CVD, and at the same time, Al(NO 3 ) 3 9H 2 O electrolysis in (CH 3 ) 2 NC(O)H can produce Al 3+ . Because of the combination of COOH − and Al 3+ , the CNT is dispersed uniformly [44].…”

AbstractNanocarbon materials (carbon nanotubes, graphene, graphene oxide, reduced graphene oxide, etc.) are considered the ideal toughening phase of ceramic matrix composites because of their unique structures and excellent properties. The strengthening and toughening effect of nanocarbon is attributed to several factors, such as their dispersibility in the matrix, interfacial bonding state with the matrix, and structural alteration. In this paper, the development state of nanocarbon-toughened ceramic matrix composites is reviewed based on the preparation methods and basic properties of nanocarbon-reinforced ceramic matrix composites. The assessment is implemented in terms of the influence of the interface bonding condition on the basic properties of ceramic matrix composites and the methods used to improve the interface bonding. Furthermore, the strengthening and toughening mechanisms of nanocarbon-toughened ceramic matrix composites are considered. Moreover, the key problems and perspectives of research work relating to nanocarbon-toughened ceramic matrix composites are highlighted.

“…The central tube (tube 1 in Fig. 7-a) first attracts another 6 tubes to form the first shell layer surrounding itself (tube 2-7), then the second shell layer with 12 tubes (tube [8][9][10][11][12][13][14][15][16][17][18][19] is formed, and so on. With this defined order of growth, the surface area of the bundle is kept at a minimum.…”

“…In terms of reinforcement, CNTs possess the highest Young's modulus and strength of all known fibers [3,4] and are widely used in reinforcing polymer [5], metal [6][7][8][9][10] and ceramic [11] and cementitious material [12]. The small size of CNTs allows them to arrest cracking [13,14] in the composite from the nanometerscale [12].…”

“…Our limited understanding of the agglomeration process and morphology of CNTs hinders their application in alkaline environments with unstable dispersion, such as in clay and soil [34], cementitious material [35], and ceramic [11] based composites. With unstable CNT dispersion it is important to understand the size and morphology of the CNT agglomeration and its formation process.…”

“…The brittleness of monolithic ceramics had limited their use in many applications [1]. Fortunately, removal of this limitation was made possible through the development of composites [2], nanocomposites [3], and hybrid nanocomposites [4,5]. Hybrid ceramic nanocomposites are advanced ceramic materials obtained by reinforcing a ceramic matrix with two nano-reinforcements that have different morphologies and/or attributes.…”

In the current work, an improved model to estimate the thermal conductivity of spark plasma sintered nanocomposites is presented. In the developed model, the thermal conductivity of the matrix was modeled as a function of the average matrix crystallite size rather than taking a constant matrix thermal conductivity. The model has been validated against experimentally measured thermal conductivity of Al 2 O 3-SiC-CNT hybrid nanocomposites. Using the experimental and modeling results, it was shown that the addition of SiC and CNT inclusions to alumina resulted in a decrease in its thermal conductivity. The main reason for this decrease was found to be the reduction in the thermal conductivity of the alumina matrix itself because of the reduction in the crystallite size. Additional reduction in the composite thermal conductivity was due to the matrix-inclusion interface resistance and porosity. The predicted and measured thermal conductivities were found to be in good agreement.
