Latest Patents

One of Sugiura's latest patents is a method and device for producing heat-resistant composite materials. This invention involves supplying a mixed gas containing a precursor gas, an additive gas, and a carrier gas to a preform stored in an electric furnace. Through chemical vapor deposition or chemical vapor phase impregnation, silicon carbide is deposited to form a film. The preform consists of multiple fiber bundles, which include numerous fibers. This composite material integrates the fibers and fiber bundles through the deposition of silicon carbide, achieving uniformity in embedding and growth rate of the silicon carbide film.

Another notable patent by Sugiura focuses on the production of heat-resistant composite materials by impregnating a ceramic fiber preform with silicon carbide. In this method, a mixed gas containing starting material gas, an additive gas, and a carrier gas is supplied to a substrate with a minute structure. The film formation growth speed and embedding uniformity are controlled by adjusting the amount of additive gas. The starting material gas contains tetramethylsilane, while the additive gas includes chlorine-containing molecules such as methyl chloride or hydrogen chloride. This innovation ensures both the growth speed and embedding uniformity of the silicon carbide.
