Abstract
The invention relates to a method for producing a molded body, having a silicon carbide support matrix and an integral carbon structure, wherein a base body on the basis of a powder mixture containing silicon carbide or silicon and carbon and of a binder is built in layers in a generative method, and wherein a pyrolysis of the base body is effected for realizing the molded body after the binder has been cured, wherein the carbon content of the carbon structure is adjusted by way of the pyrolysis of the binder and by way of the carbon content of the powder mixture or infiltration of a carbon material into the silicon carbide support matrix.
Claims16
A method for producing a molded body having a silicon carbide support matrix and an integral carbon structure, said method comprising:
- building a layered base body using a generative method from a powder mixture containing carbon, a binder, and at least one of silicon and silicon carbide;
- curing the binder;
- and
- pyrolyzing the base body including the binder after the binder has been cured to form the molded body, said pyrolyzing forming a silicon carbide support matrix and an integral carbon structure, wherein a carbon content of the carbon structure is defined by a free carbon in its entirety and is adjusted by way of the pyrolysis of the binder and by way of the carbon content of the powder mixture or infiltration of a carbon material into the silicon carbide support matrix.
