Additive manufacturing of tailored macroporous ceramic structures for high temperature applications.
Here we outline work in the last dec ade on the processing of uhtcs with a reinforcing fiber phase for enhanced fracture toughness.
A ceramic is any of the various hard brittle heat resistant and corrosion resistant materials made by shaping and then firing a nonmetallic mineral such as clay at a high temperature.
The rmi process is often chosen as it is rapid and can be used with various geometries to efficiently fill both large and small porosity to create a dense matrix.
Ceramic fibers in cmcs can have a polycrystalline structure as in conventional ceramics.
Common examples are earthenware porcelain and brick.
