Method for fabrication of high density SiCf/SiC composites with homogeneous microstructure

摘要

The present invention relates to a method for preparing a silicon carbide fiber-reinforced silicon carbide composite having a uniform microstructure, and more particularly, to a method for manufacturing a silicon carbide fiber-reinforced silicon carbide composite having a uniform microstructure, comprising the steps of: (1) preparing a tubular silicon carbide (SiC) And a step (2) of forming a silicon carbide matrix phase in the preform by supplying the raw material gas to the outer circumferential surface and the inner circumferential surface of the preform while rotating the tubular silicon carbide fiber preform, A process for producing a silicon carbide composite (SiC _f / SiC) is provided. The method for producing a silicon carbide fiber-reinforced silicon carbide composite according to the present invention can produce a high-density composite having improved microstructure uniformity in a short period of time. As compared with the conventional manufacturing method, There is an effect that can be saved. In addition, the composites produced in accordance with the present invention can be used as high strength / high toughness structural materials in gas turbines, aerospace and next generation reactors.
