Continuous SiC fiber-reinforced SiC matrix composites (SiCf /SiC) have been considered to be a key material as structural components for aerospace and energy fields. This paper reviews novel fabrication process of continuous SiCf /SiC composites with high performance based on interfacial and microstructure control and our approach to improvement of mechanical and thermal properties of SiCf /SiC composite based on modeling and analysis. The simple fabrication process of two-dimensional SiCf /SiC composite using sheet stacking and hot-pressing based on interfacial and microstructure control was developed, and dense SiCf /SiC composite with excellent mechanical and thermal properties was successfully obtained. Furthermore, novel fabrication process of SiCf /SiC composite using EPD process was proposed and it was demonstrated that EPD process is expected to be an effective way to control the fiber/matrix interface and the microstructure of SiCf /SiC composite with high performance. Interfacial properties of SiCf /SiC composite were quantitatively evaluated by push-in test using nanoindenter, and these quantitative results well agreed with the results on their mechanical properties, and these results lead to the material design of the SiCf /SiC composite with high mechanical properties and the optimization of its fabrication process. Simple model of thermal conductivity of SiCf /SiC composite based on series model of multilayered structure was suggested by our experimental data, and higher thermal conductivity of SiCf /SiC composite was successfully achieved by microstructure control.

“…Because the fabrication of high density SiC f /SiC is essential, a range of techniques, such as reaction sintering (RS), 16 chemical vapor infiltration (CVI), 17 polymer impregnation and pyrolysis (PIP), 18 nano-infiltrated transient eutectoid (NITE) 19 and electrophoretic deposition (EPD)-based technique, [20][21][22][23][24][25][26] have been used to infiltrate the matrix phase into the voids of a fiber-preform. Among these, EPD-based technique has several advantages, such as precise controllability of the composition, simple deposition apparatus, fast and even growth rate, and ease of depositing multilayer films with a controlled thickness.…”

“…[28][29][30] Recently, several successful attempts have been made to use EPD-based technique for the fabrication of SiC f /SiC. [20][21][22][23][24][25][26] Generally, organic solvents are used over water for EPD because of the evolution of hydrogen and/or oxygen bubbles from water electrolysis in DC electric fields. Although efforts have been made to produce uniform deposition in an aqueous system by minimizing the water electrolysis under DC electric fields, including the use of graphite electrode 31 and pulsed DC signal, 32 AC-EPD in an aqueous suspension has emerged recently as a successful processing technique for the deposition of a range of particles.…”

Intermediate temperature solid oxide fuel cells (IT‐SOFCs) were fabricated depositing proton conducting BaCe0.9Y0.1O3–x (BCY10) thick films on cermet substrates made of nickel oxide–yttrium doped barium cerate (NiO–BCY10) using electrophoretic deposition (EPD) technique. The influence of the EPD parameters on the microstructure and electrical properties of BCY10 thick films was investigated. Deposited BCY10 thick films together with green anode substrates were co‐sintered in a single heating treatment at 1,550 °C for 2 h to obtain dense electrolyte and suitably porous anodes. The half‐cells were characterised by field emission scanning electron microscopy (FE‐SEM) and by X‐ray diffraction (XRD) analysis. A composite cathode specifically developed for BCY electrolytes, made of La0.8Sr0.2Co0.8Fe0.2O3(LSCF, mixed oxygen‐ion/electronic conductor) and BaCe0.9Yb0.1O3–δ (10YbBC, mixed protonic/electronic conductor), was used. Fuel cells were prepared by slurry coating the composite cathode on the co‐sintered half‐cells. Fuel cell tests and electrochemical impedance spectroscopy (EIS) were performed in the 550–700 °C temperature range. A maximum power density of 296 mW cm–2 was achieved at 700 °C for electrolyte deposited at 60 V for 1 min.
