Abstract
A process of high-strength Carbon-fiber-reinforced SiC matrix (C/SiC) composite materials with a rapid and low-cost manufacturing method was examined in this study. In this process, the space between fibers in a 2D carbon fiber preform was impregnated with SiC powder slurry by pressure or vacuum assisted infiltration before the polymer infiltration and pyrolysis (PIP) or the melt infiltration (MI) process. The bulk density of the powder-filled preform achieved 1.3 g/cm^3. Then, the powder-filled preform was further densified by the PIP method or the MI method. Through these experiments, SiC powder infiltration behavior during the pressure or the vacuum assisted slurry infiltration process was discussed, and basic mechanical properties of C/SiC composites fabricated by these processes were evaluated.
