“…As mentioned above, nanocarbon has a tendency to spontaneously condense, and although it is beneficial in promoting the formation of functional networks, the aforementioned disadvantages interfere in the preparation of nanocarbon-reinforced ceramic matrix composites [26]. More specifically, aggregated nanocarbon causes stress concentrations and even acts as a structural defect to reduce the mechanical properties of nanocarbon-reinforced ceramic matrix composites [24,31].…”

“…Therefore, for the composites people just use energy dissipation (i.e., the integral of stress-strain curves) to define the toughness. The common methods used for the evaluation of the resulting composite materials have been tabulated (see Table 1) [23][24][25][26][27][28][29][30]. The foregoing are critical factors that affect the properties of nanocarbonstrengthened and-toughened ceramic matrix composites.…”

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.

“…Ceramic matrix composites (CMC) are extremely important strategic materials for high‐temperature structural applications in aerospace and other fields, owing to their impressive properties at high temperatures, such as high strength, low density and chemical inertness. The materials’ main drawbacks limiting their wide applicability, including relatively low toughness, processing‐related challenges and the complexity and inefficiency of molding .…”

This article reports a novel method for three‐dimensional (3D) printing of continuous fibers into ceramics to improve the mechanical properties of printed ceramics, which is difficult in other 3D printing technologies. The ceramics were derived by pyrolysis of thermoplastic ceramic precursor feedstocks, which were prepared by two methods. One is homogeneously mixing thermoplastic resins and ceramic precursors. The feedstocks prepared by this method exhibit good thermoplastic properties and can be extruded into filaments. Ceramics were obtained by heating the feedstocks to 1100°C in argon atmosphere. The ceramics were amorphous and remained stable during 1100‐1300°C; at 1400°C they decomposed into β–SiC with simultaneous volatile gas generation. Above 1400°C, their quality decreased significantly due to cracking of ceramic skeletons. The other method is directly heating, extruding and printing the ceramic precursor. The precursors showed good printability and complex ceramic structures were printed with continuous carbon fibers inside. The continuous carbon fibers improved the flexural strength of pyrolytic ceramics, which is about 7.6 times better than that of the ceramics without fibers. The novel method unravels the potential of 3D printing of continuous fibers into ceramics with complex lightweight structures to improve the strength.

“…[1][2][3] However, a uniform ceramic slurry having a high solid content and a low viscosity must be prepared that is a prerequisite for the implementation of this process. [6][7][8] More than 95% of the world production of SiC comes via the Acheson process even today. As the solid phase content increases, the viscosity increases sharply in the slurry and cannot meet the requirements of colloidal molding.…”

In this paper, the influence of surface oxide layer of SiC powder on the rheological behavior of its slurry was studied by acid washing, HF etching, and calcination oxidation processes. Zeta potential, particle size, inductively coupled plasma atomic emission spectrometry (ICP‐AES), energy dispersive X‐ray spectroscopy, and viscosity tests indicated the main factor that resulted in high viscosity of slurry is impure ions existing either on the powder surface or in the water phase, rather than the surface oxide layer. After the impure ions are removed, the surface oxide layer formed at a calcination temperature range of 400°C‐750°C does not cause an increase in the slurry viscosity, but contributes to an improvement in the rheological properties of SiC slurry.
