Carbon fiber-reinforced SiC composites were prepared by reaction-bonding. The formation of SiC (3C type) took place by a reaction between carbon from phenol resin and silicon powder above 1320°C and completed at 1420°C. This reaction did not damage the carbon fiber, and fiber pull-out was observed on the fracture surface. The bulk density and the flexural strength of these composites were 1.7-1.8g/cm3 and -130MPa, respectively. Impregnation with molten silicon at 1600°C increased the bulk density but decreased the flexural strength, due to the reaction of carbon fiber with silicon.
