Porous Si/SiC Composite Based on Nonwoven Cellulosic Fabrics: Synthesis and Characterization
The microstructure and properties of porous Si/silicon carbide (SiC) composites manufactured from nonwoven cellulosic fabrics have been investigated. A fibrillar reaction product with a microstructure reproducing the initial preform morphology consisting of -SiC and unreacted Si was obtained. Improvement of strength is expected to be achieved by increase of SiC content and reduction of porosity.
