摘要： 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.

摘要： A method of forming a ceramic matrix composite includes applying a binder comprising water and 5% to 15% polyvinyl alcohol to a ceramic material and decomposing the binder to leave behind a discontinuous carbon layer within the ceramic material. The step of applying the binder includes one of a spraying, pipetting, painting, immersing, and pre-pregging technique.

摘要： A method of making a ceramic matrix composite (CMC) brake component may include the steps of applying a pressure to a mixture comprising ceramic powder and chopped fibers, pulsing an electrical discharge across the mixture to generate a pulsed plasma between particles of the ceramic powder, increasing a temperature applied to the mixture using direct heating to generate the CMC brake component, and reducing the temperature and the pressure applied to the CMC brake component. The ceramic powder may have a micrometer powder size or a nanometer powder size, and the chopped fibers may have an interphase coating.

摘要： A method for making a composite material includes disposing a quantity of liquid comprising at least 90 weight percent molten boron within pores of a porous preform, the preform comprising a preform material; and reacting at least a portion of the molten boron with a portion of the preform material to form a solid ceramic reaction product, thereby forming a ceramic matrix composite material. An article comprises a composite material; the composite material comprises a fibrous phase disposed within a matrix. The matrix comprises silicon carbide, boron carbide, and boron silicide.
