To develop high performance Carbon-Carbon composite, preliminary practices of SiC infiltration into monolithic porous carbon and Carbon-Carbon composite preforms were performed using Pulse Chemical Vapor Infiltration process, in which the concentration of CH3SiCl3 was fixed at 4.5mol%.The preferable conditions for the porous carbon preforms were determined as follows: reaction temperature of 1173K and holding time of 1.5sec. for the preform which has 29vol% porosity and 0.2 to 0.5μm average pore diameter, 1273K and 2.0sec. for that which has 45vol% and 10 to 40μm.Using the preferable condition, SiC matrix was deposited initially around the center of thickness and finally over the full thickness of the porous carbon preforms.In case of the porous Carbon-Carbon composite preforms, SiC matrix infiltration was also observed at three temperatures of 1173K, 1273K and 1373K.65vol% of initial porosity was infiltrated with β -SiC in the condition of 1373K and 1.5sec..
