LSI (Liquid silicon infiltration) is one of most economic method for fabricating the C/C-SiC composite because of its short process time and low cost. However, the matrix of C/C-SiC composite contains lots of un-reacted free silicon that degrade its high temperature properties over 1300℃. In this study, the several types of alloys (Ti, Co, Al and Mo) were infiltrated into the C/C composite in vacuum condition to form silicides or carbides that have resistance in high temperature environment. The metal elements were successfully infiltrated with molten Si into C/C composite preform and the micro structure of each alloy infiltrated composite was observed and also mechanical properties were measured and analyzed.
