Article Preview

The characterization of RS-SiC and RS-SiCf/SiC composite materials fabricated by the reaction sintering process has been investigated, based on the detailed examination of their microstructures. In this composite system, Tyranno SA SiC fiber and Hi-Nicalon SiC fiber were used as reinforcing materials. The green bodies for RS-SiC and RS-SiCf/SiC materials were prepared with the complex matrix slurry of SiC and C particles. The density and the room temperature strength of RS-SiC material with the starting SiC particles of 0.3 µm showed about 3.1 Mg/m3 and about 520 MPa, respectively, even if there were large amount of residual silicon (about 19 %). The flexural strength of Hi-Nicalon/SiC composites greatly decreased at the temperature higher than 1000 􀀀
