β-silicon carbide whiskers were synthesized on a carbon fabric using a vapor-solid (VS) mechanism. The morphologies of the SiC deposits changed as deposition time increased. Pore size distribution and mean pore size of the fabric filter was reduced by whisker growth. A particle-trapping test was conducted to examine the efficiency of the filter. Then, the size of the particles infiltrated within the filter was analyzed. The maximum increase rate of the particle trap rate was 136.6% by whisker growth. The fine particles ranged from 550 to 800 nm and could be trapped by forming whiskers on the carbon filaments of the fabric filter. The carbon fabric filter's gas permeability is 6 times higher than conventional honeycomb filters.
