A production method for a composite material, which includes a porous substrate and a silicon carbide film formed on a surface of a material forming the porous substrate, includes causing a silicon source containing a silicon atom, a chlorine source containing a chlorine atom, and a carbon source containing a carbon atom to react with each other to form the silicon carbide film on the surface of the material forming the porous substrate.

Production method for composite material

This disclosure is to make it possible to easily stabilize a chlorosilane polymer while preventing a solid chlorosilane polymer from being generated. Disclosed is a method for stabilizing a chlorosilane polymer generated secondarily in a step of a chemical vapor deposition method using chlorosilane-based gas, the method including: a step of bringing alcohol into contact with the chlorosilane polymer, degrading the chlorosilane polymer to alkoxide, hydrogen chloride and hydrogen, and diluting the degraded alkoxide with the alcohol; and a step of performing hydrolysis for the alkoxide.

Method for stabilizing chlorosilane polymer

Provided is a method of producing a silicon compound material, including the steps of: storing a silicon carbide preform in a reaction furnace; supplying a raw material gas containing methyltrichlorosilane to the reaction furnace to infiltrate the preform with silicon carbide; and controlling and reducing a temperature of a gas discharged from the reaction furnace at a predetermined rate to subject the gas to continuous thermal history, to thereby decrease generation of a liquid or solid by-product derived from the gas.

Method of producing a silicon compound material and apparatus for producing a silicon compound material

A reheating collection device for a gas phase process is provided with a container elongated in an axial direction along an axis to define a chamber, an inflow path and an exhaust path respectively in communication with the chamber and apart in the axial direction from each other, and a heater heating the chamber between the inflow path and the exhaust path.

Reheating collection device for gas phase process

A device of executing vacuum processing has a chamber capable of keeping the chamber as a whole in a depressurized state; a feeding roller so disposed as to hang a reinforcement fiber down in the chamber; a processor so disposed in the chamber as to pass the reinforcement fiber hung down in the chamber through the processor; a capture device so disposed as to capture and keep a leading end of the reinforcement fiber passing the processor and vertically falling down in place; a winding bobbin configured to wind the reinforcement fiber processed by the processor; and a resilient cord withdrawn in synchronism with the winding bobbin from a first position where the resilient cord surrounds the leading end kept in place by the capture device to a second position where the resilient cord gets in contact with and leads the reinforcement fiber to the winding bobbin.

Vacuum processing device

When a molded fabric body (X) is impregnated with a powder (K) of a predetermined material, there are performed a first step of dispersing the powder (K) in a liquid to prepare a slurry, and a second step of burying the molded fabric body (X) made of fiber bundles in the slurry and vibrating the slurry by use of a predetermined vibrator (M). Furthermore, in the second step, the vibrator (M) is moved along a surface of the molded fabric body (X). As a result, it is possible to improve the rate of impregnation of the powder (K) more than that in the conventional cases, irrespective of the shape of the molded fabric body (X).

Powder material impregnation method and method for producing fiber-reinforced composite material

A ceramic composite material is comprised of a fabric of fibers of an inorganic substance; and a matrix for combining the fibers. The matrix consists essentially of a ceramic. The matrix is formed by burying the fabric in a mixture of a powder of carbon, a powder of silicon and a medium including an organic solvent, producing an oscillation in the mixture to impregnate the fabric with the mixture, and calcining the fabric impregnated with the mixture.
