“…When HTT is lower than 1500°C, the decrease of modulus is mainly due to the microstructure damage caused by heat treatment, such as microcrack growth of SiC matrix and slight interface disbonding. 15,16 However, the modulus decreases greatly during high HTT. The first reason is that the HTT above 1500°C greatly increases the graphitization of the amorphous PyC interface, and the heat treatment promotes a smoother surface of the…”

Two-dimensional (2D) carbon fiber reinforced silicon carbide (C/SiC) composites with different initial strength were prepared by chemical vapor infiltration (CVI). After tensile property testing, results exhibited that as the heat-treatment temperature (HTT) increases to 1900°C, the tensile strength and toughness of the low strength specimen (LSS) increased by 110% and 530%, while the high strength specimen (HSS) increased by 5.4% and 550%, respectively. As observed from morphologies, the heat treatment increases the graphitization of the amorphous PyC interphase, which leads to the weakening of interfacial bonding strength (IBS). Meanwhile, the defects arising from heat treatment cause thermal residual stress relaxation. Therefore, the tensile strength and toughness of LSS with relatively high initial IBS increase significantly as HTT increases. For HSS with moderate initial IBS, the heat treatment slightly improves the tensile strength, but significantly improves the toughness. Consequently, the post-heat-treatment tensile properties of 2D C/SiC composites can be regulated by varying HTTs and different initial strength.

Electrospun nanofibers have promising properties and serve an important role in various applications ranging from biomedical engineering to mechanical engineering. Although electrospun nanofibers are not used worldwide, the limited research conducted thus far provides a rudimentary understanding of nanofibers and explores the potential areas that have attracted attention for commercialization. However, the lack of a comprehensive understanding of the properties of nanofibers in various applications severely limits their functionality. This review provides clear insights into modifying the morphology of nanofibers by adjusting various parameters to meet specific application requirements. Various applications, including membrane distillation, reinforcement, and self‐healing, and the corresponding desired properties are discussed in detail. Approaches for enhancing the application‐specific properties of electrospun nanofibers are also discussed. This discussion provides significant guidance for the design of novel electrospun composites with excellent properties. Finally, the challenges in research and the opportunities for future development are presented.

“…SiC has been regarded as one of the most promising structural ceramics owing to its high strength-to-weight ratio, high thermal conductivity coupled with low thermal expansion, excellent resistance to abrasion and corrosion, and most importantly high strength retention at high temperatures (approaching 1600°C) [1][2][3][4][5]. All these characteristics have led to a wide range of applications, such as abrasive and cutting tools, high-temperature kilns, composite armor and gas turbines engines [6][7][8].…”
