【 摘 要 】

Efforts to develop fibrous ceramic monoliths for primarily structural applications are described. Fibrous monoliths (FMs) are relatively insensitive to flaws and can exhibit graceful failure and large work-of-fracture values. They can be inexpensively produced in a wide variety of forms by conventional ceramic processing methods such as extrusion. The FM project that is the subject of this report involved investigations to (1) develop FMs that can be pressureless sintered rather than hot pressed, (2) develop technologies to continuously extrude FM filaments and inexpensively fabricate FM components, (3) evaluate the performance of commercial and new, prototype FMs, (4) develop micromechanical models to guide the design of new FMs and predict their properties, and (5) forge collaborations with industry to produce useful parts.
