Mechanical properties of unidirectional and crossply SiCf/SiC composites using SiC fibers with carbon interphase formed by electrophoretic deposition process

Fabrication of SiCf/SiC composites through hybrid processing via chemical vapor infiltration, electrophoretic deposition, and liquid silicon infiltration

“…The observed flexural strength value is relatively lower even though the porosity is very low. Similar lower flexural strengths of about 130 − 170 MPa were reported earlier [17] in the case of cross-ply SiC f /SiC composites and these lower values are explained based on the fiber orientation. The SiC fibers aligned in 0° direction would contribute for toughening and strengthening of composites effectively whereas the fibers aligned in 90° direction may not contribute since these fibers exist parallel to the crack propagation during bending test.…”

“…In particular, there has recently been a significant boost in the use of EPDbased techniques for fabricating various CMCs. However, these studies are limited to the fabrication of relatively small-sized composites, and there are still some challenges [9,[17][18][19][20][21].…”

Electrical Discharge Machining of Silicon Carbide Ceramic of Plane Processing

“…It is widely used in water pumps, heat exchangers, bearings, and space telescopes [1,2]. It possesses excellent properties, such as oxidation resistance, high mechanical strength at elevated temperature, high hardness, high corrosion resistance, high thermal conductivity, and high thermal shock resistance [3][4][5][6]. However, SiC ceramics have grinding difficulties due to their hard and brittle features.…”

Microstructure and mechanical properties of SiC fibres after exposure at elevated temperature

“…Recently, the microstructure and mechanical property of SiC fibre-reinforced CMCs were investigated widely, [4][5][6] while the corresponding research on SiC fibre itself has been relatively insufficient. Essentially, SiC fibre is not composed of pure polycrystalline SiC.…”
