<p>A reinforced ceramic structure, such as a superplastic forming die for forming a metal part, has a body of cast silica/calcium aluminate or mullite based ceramic material; and a plurality of reinforcing rods, made of monolithic fused oxides of silicon or aluminum, cast into said ceramic body. The rods have a thickness between 1/8"-2.0" and are spaced apart on centers by about 2-10 times the diameter of the rods. The rods are made of monolithic fused oxides of silicon or aluminum. A process for manufacturing the reinforced ceramic die includes selecting a casting box having internal dimensions equal to desired external dimensions of the ceramic die and having a floor and an open top. A model of the metal part is attached to the floor of the casting box. Pairs of aligned holes are bored in inside surfaces of the casting box, and a reinforcing rod is mounted in each of the pairs of holes. The casting box is filled with a pourable cementitious material to the open top. <IMAGE></p> |
