"SYNTHESIS OF SILICON CARBIDE FIBERS FROM …
2014/9/4· Silicon carbide (SiC) is widely used in many fields due to its unique properties. Bulk SiC normally has a flexural strength of 500 - 550 MPa, a Vickers hardness of ~27 GPa, a Young''s modulus of 380 - 430 GPa, and a thermal conductivity of approximately 120 W/mK. SiC fibers are of great interest since they are the good candidates for reinforcing ceramic matrix composites (CMCs) because of the
