Abstract:
A method for producing a shaped article of a ceramic composite, said composite comprising fibers dispersed in ceramic matrix materials, said method comprising the steps of:providing a stable formed support having a plurality of indentations formed into a surface thereof; disposing a fiber preform adjacent to said surface having said indentations of said stable formed support, said fiber preform comprising packed fibers; providing at least one precursor of said ceramic matrix materials to said fiber preform; heating said fiber preform with said at least one precursor on said stable formed support to a temperature greater than or equal to a melting point of said at least one precursor; allowing said precursor in a molten state to infiltrate said fiber preform for an infiltration time sufficient to result in a melt-infiltrated composite; and cooling said melt-infiltrated composite to result in said shaped article of said ceramic composite.
