Fabrication of fiber-reinforced ceramic composites by the modified slurry infiltration technique

A new technique for the homogeneous infiltration of concentrated and viscous ceramic filler slurries into stacked 2D-woven fabrics has been developed by introducing a flexible mold. The inner space of the mold expanded during slurry infiltration, which enhanced penetration of the viscous slurry into the woven fabric layers. The subsequent precursor impregnation and pyrolysis process yielded fiber-reinforced ceramic composites with scarce macropores between the fabric layers.
