Embodiment Construction

[0022] Hereinafter, some embodiments will be described with reference to the drawings.

[0023] A suitable application of the ceramic matrix composite material according to one embodiment is a mechanical part exposed to a high-temperature environment such as a component part of a jet engine for an aircraft, and examples thereof include turbine blades, combustion chambers, afterburners, and the like. Of course, it can also be applied to other purposes.

[0024] A ceramic matrix composite material according to one embodiment generally includes a fabric made of inorganic fibers such as silicon carbide (SiC), and a matrix that binds the fabric made of inorganic substances such as SiC. The manufacturing method of this ceramic matrix composite generally includes: making aggregate powder as a matrix raw material in a binder such as a thermoplastic resin to form a sheet, laminating the sheets and fabrics alternately, and applying pressure to make the aggregate soaks into the fabric. ...

Abstract

This method for manufacturing a ceramic-based composite material comprises: kneading and mixing an aggregate powder that includes SiC powder and a binder including at least one selected from the group consisting of a thermoplastic resin and wax to form a composition including the aggregate powder and binder; pressing the composition to form a sheet; alternately laminating a fabric made from reinforced fibers that include SiC fibers and the sheet; pressing the laminate of the fabric and sheet; and generating a matrix that binds the reinforced fibers to each other.

Description

technical field [0001] The present disclosure relates to a method of manufacturing a ceramic matrix composite material applicable to devices requiring high-temperature strength, such as jet engines for aircraft. Background technique [0002] Ceramics have extremely high heat resistance, but on the other hand, most ceramics have a disadvantage of being brittle. Conventionally, in order to overcome brittleness, attempts have been made to composite ceramics with fibers of inorganic substances such as SiC as a base material (matrix). [0003] For compounding, methods such as vapor phase impregnation (CVI), liquid phase impregnation (for example, polymer melt impregnation pyrolysis (PIP)), solid phase impregnation (SPI), and molten metal impregnation (MI) have been proposed. For example, according to the PIP method, a fabric made of fibers such as SiC is impregnated with a polymer solution, fired at a high temperature to be ceramicized, and the ceramic becomes a matrix and compo...
