Abstract

Ceramic fiber-reinforced composites have good mechanical properties in hardness and durability. In this study, we studied the formation of SiC/C composites from methyltrichlorosilane and hydrogen by the Pulse-chemical vapor infiltration(PCVI) to deposit silicon carbide around the changes of the amount of deposit. SiC/C composites formed at $950^{\circ}C$, 20torr, Pulse-times (5s/60s). SEM of the cross sectional area of semple showed deposited silicon carbide around fibers.
