Abstract
A method of making a carbon-carbon composite may comprise forming a Silicon-Aluminum-Oxygen-Nitrogen (SiAlON) precursor suspension and infiltrating a fibrous preform with the SiAlON precursor suspension. A SiAlON forming heating treatment may be performed on the fibrous preform to form SiAlON particles. The fibrous preform may be densified using chemical vapor infiltration to form a densified fibrous preform.
Claims13
A method of making a carbon-carbon composite, comprising:
- forming a Silicon-Aluminum-Oxygen-Nitrogen (SiAlON) precursor suspension by combining an aluminum source, a positively charged silicon source, and a carrier fluid;
- infiltrating a fibrous preform with the SiAlON precursor suspension;
- performing a SiAlON forming heating treatment on the fibrous preform to form SiAlON particles;
- and
- densifying the fibrous preform by chemical vapor infiltration (CVI) to form a densified fibrous preform.

A method of making a carbon-carbon composite, comprising:
- partially densifying a fibrous preform;
- infiltrating the fibrous preform with a first Silicon-Aluminum-Oxygen-Nitrogen (SiAlON) precursor suspension having an aluminum source, a positively charged silicon source, and a carrier fluid;
- performing a first SiAlON forming heating treatment on the fibrous preform;
- and
- densifying the fibrous preform to form a fully densified fibrous preform.
