Introduction
M Dennis Petry is a notable inventor based in New Paris, OH (US), recognized for his contributions to the field of ceramic composites. He holds 2 patents that showcase his innovative approaches to material science and engineering.
Latest Patents
His latest patents include advancements in zircon-carbon for ceramic composite fiber coatings and fine-grained zircon powder. The first patent describes a carbon-rich zirconia-silica sol prepared by dissolving zirconyl nitrate hydrate in absolute ethanol, mixing it with a silicon alkoxide, and combining this with a polyelectrolyte. This innovative sol/polyelectrolyte mixture can be utilized to coat continuous fiber tow or filaments, produce nanosized zircon powder, and create a porous zircon membrane material. The second patent outlines an improved method for producing a fiber-reinforced ceramic composite featuring a monazite interface between the reinforcing fiber and the ceramic matrix. This method involves coating each filament in a continuous fiber tow with an aqueous sol that forms monazite after high-temperature heat treatment, followed by embedding the fiber in a suitable ceramic matrix and densifying the composite.
