Estimating the term…
Organometallic ceramic precursor binders are used to fabricate shaped bodies by different techniques. Exemplary shape making techniques which utilize hardenable, liquid, organometallic, ceramic precursor binders include the fabrication of negatives of parts to be made (e.g., sand molds and sand cores for metalcasting, etc.), as well as utilizing ceramic precursor binders to make shapes directly (e.g., brake shoes, brake pads, clutch parts, grinding wheels, polymer concrete, refractory patches and liners, etc.). A preferred embodiment of the invention involves the fabrication of preforms used in the formation of composite articles.
A process for fabricating shaped metal matrix composite articles by a spontaneous infiltration process, said process comprising (1) providing a solventless coating on at least a portion of the surface of a filler material with a hardenable, liquid, organometallic, ceramic precursor binder to form a filler material/binder mixture, (2) forming a shape from said filler material/binder mixture, (3) hardening said binder in said filler material/binder mixture to form a permeable preform and (4) spontaneously infiltrating a matrix metal into the permeable preform to form a shaped metal matrix composite article.
