Solid freebody forming of ceramics from polymerizable slurry

A system is described for forming three-dimensional parts from a polymerizable slurry. This liquid is delivered from a fine nozzle to build up the component as a series of layers described from a CAD drawing of the part. This is one of a family of solid freebody forming methods. The layerwise process lends itself particularly to chemically synthesized materials where shrinkage and mass transport are major problems. The technique also has considerable potential for combining various materials into a single component.

Fibrous monoliths: Economic ceramic matrix composites from powders [Final report]

The project was to develop and perform pilot-scale production of fibrous monolith composites. The principal focus of the program was to develop damage-tolerant, wear-resistant tooling for petroleum drilling applications and generate a basic mechanical properties database on fibrous monolith composites.
