Patent number: 10221104Abstract: A mixed gas containing a precursor gas, an additive gas and a carrier gas is supplied to a preform stored in an electric furnace, and silicon carbide is deposited by chemical vapor deposition or chemical vapor phase impregnation to form a film. The preform includes multiple fiber bundles, and the fiber bundles include multiple fibers. This heat-resistant composite material includes a ceramic fiber preform impregnated with silicon carbide, and producing the composite material involves a step in which silicon carbide is deposited between the fibers to integrate the fibers which configure the fiber bundles, and a step in which silicon carbide is deposited between the fiber bundles to integrate the fiber bundles. Hereby, uniformity of embedding and growth rate of the silicon carbide film are both attained.Type: GrantFiled: May 26, 2016Date of Patent: March 5, 2019Assignees: IHI CORPORATION, THE UNIVERSITY OF TOKYOInventors: Takeshi Nakamura, Masato Ishizaki, Kozue Hotozuka, Yasuyuki Fukushima, Yukihiro Shimogaki, Takeshi Momose, Hidetoshi Sugiura, Kohei Shima, Yuichi Funato

Patent number: 9822445Abstract: By using chemical vapor deposition or chemical vapor infiltration, silicon carbide is deposited on a preform 100 accommodated in a reaction furnace 11 for film formation, and the amount of additive gas added to raw material gas and carrier gas to be supplied to the reactive furnace 11 is used to control the growth rate and filling uniformity at film formation of silicon carbide. When the film formation of silicon carbide follows a first-order reaction, the amount of added additive gas is used to control the sticking probability of the film-forming species. When the film formation of silicon carbide follows a Langmuir-Hinshelwood rate formula, the amount of added additive gas is used to make a control so that a zero-order reaction region of the Langmuir-Hinshelwood rate formula is used.Type: GrantFiled: February 12, 2015Date of Patent: November 21, 2017Assignees: IHI Corporation, The University of TokyoInventors: Takeshi Nakamura, Masato Ishizaki, Kenji Fuchigami, Kozue Hotozuka, Yukihiro Shimogaki, Takeshi Momose, Yasuyuki Fukushima, Noboru Sato, Yuichi Funato, Hidetoshi Sugiura
