Latest Patents

Hotozuka's latest patents focus on methods for producing heat-resistant composite materials. One of her notable inventions involves a production method and device that utilizes a mixed gas containing a precursor gas, an additive gas, and a carrier gas. This gas is supplied to a preform stored in an electric furnace, allowing for the deposition of silicon carbide through chemical vapor deposition or chemical vapor phase impregnation. The resulting composite material features a ceramic fiber preform impregnated with silicon carbide, which enhances the integration of fibers within the fiber bundles. This method ensures uniformity in embedding and growth rates of the silicon carbide film.

Another patent by Hotozuka describes a similar production process, where a mixed gas is supplied to a substrate with a minute structure. The method controls the film formation growth speed and embedding uniformity by adjusting the amount of additive gas in relation to the starting material gas. This innovative approach utilizes tetramethylsilane as the starting material gas and a chlorine-containing molecule, such as methyl chloride or hydrogen chloride, as the additive gas. Both patents highlight her expertise in achieving optimal results in the production of heat-resistant composite materials.
