Abstract
A method of treating a carbon/carbon composite is provided. The method may include infiltrating a carbonized fibrous structure with hydrocarbon gas to form a densified fibrous structure. The method may include treating the densified fibrous structure with heat at a first temperature range from about 1600 to about 2400° C. to form a heat treated densified fibrous structure. The method may include infiltrating the heat treated densified fibrous structure with silicon to form a silicon carbide infiltrated fibrous structure.
Claims15
A method of treating a carbon/carbon composite, comprising:
- depositing at least one of graphene platelets or carbon nanotubes into a carbonized fibrous structure via a dispersion, through a vacuum impregnation process;
- infiltrating the carbonized fibrous structure with hydrocarbon gas to form a densified fibrous structure having a density in a range from about 1.65 grams per cubic centimeter to about 1.80 grams per cubic centimeter, wherein the depositing is executed prior to execution of the infiltrating the carbonized fibrous structure with hydrocarbon gas;
- treating the densified fibrous structure with heat at a first temperature range from about 1600 to about 2400° C. to form a heat treated densified fibrous structure;
- and
- infiltrating the heat treated densified fibrous structure with silicon to form a silicon carbide infiltrated fibrous structure.
A method of treating a carbon structure, comprising:
- treating a fibrous structure with heat at a first temperature ranging from about 1400 to about 2800° C. to form a carbonized fibrous structure;
- depositing at least one of graphene platelets or carbon nanotubes into the carbonized fibrous structure via a dispersion, through a vacuum impregnation process;
- infiltrating the carbonized fibrous structure with hydrocarbon gas to form a densified fibrous structure, wherein the infiltrating using the hydrocarbon gas is executed after the depositing;
- treating the densified fibrous structure with heat at a second temperature range from about 1600 to about 2400° C. to form a heat treated densified fibrous structure;
- and
- infiltrating the heat treated densified fibrous structure with silicon to form a silicon carbide infiltrated fibrous structure.
