Abstract: Methods for joining a first ceramic component to a second ceramic component to form a unitary ceramic component are provided. The method includes positioning a bonding sheet between a first ceramic component and a second ceramic component. The bonding sheet defines a plurality of voids. The method also includes densifying the bonding sheet with an infiltrate composition at a densification temperature to form a bonding interface comprising a ceramic material that forms a bonding interface between the first ceramic component to the second ceramic component into a unitary ceramic component.

Abstract: A method for repair of composite materials includes applying a formulation to a ceramic matrix composite substrate. The formulation comprises a liquid carrier, a ceramic filler dispersed within the carrier, and a polymeric binder disposed in the carrier. The method further includes removing the carrier from the formulation to form a green composition; pyrolyzing the green composition to form a porous composition; disposing a liquid metal or metalloid within the pores of the porous composition to form an intermediate composite composition; and converting the liquid metal or metalloid to solid state to form a solid composite composition.

Abstract: A method of redefining an opening in a composite component comprises filling the opening with a filling material, where the opening is defined in a body of the composite component and opens onto a surface defined by the composite component, and redefining the opening such that the opening extends into the body. Some methods comprise removing an existing coating from the surface of the composite component prior to filling the opening with the filling material and applying a new coating to the surface prior to redefining the opening such that the opening extends through the new coating and into the body. An exemplary composite component comprises a body, a surface with a coating thereon, an original opening defined through the body and filled with a filling material, and a new opening defined through the coating into the body, which may be defined at a new location from the original opening.

Abstract: A method for forming a ceramic matrix composite article includes laying up a first group of plies; laying up a second group of plies, the first and second groups of plies being adjacent to each other; compacting the first group of plies and the second group of plies in the same processing step; and performing a first infiltration process on the first group of plies. The method also includes performing a second infiltration process on the second group of plies, the first infiltration process being one of a melt infiltration process or a chemical vapor infiltration process, and the second infiltration process being the other of the melt infiltration process or the chemical vapor infiltration process.

Abstract: Ceramic matrix composite articles include, for example, a plurality of unidirectional arrays of fiber tows in a matrix having a monomodal pore size distribution, and a fiber volume fraction between about 15 percent and about 35 percent. The articles may be formed by, for example, providing a shaped preform comprising a prepreg tape layup of unidirectional arrays of fiber tows, a matrix precursor, and a pore former, curing the shaped preform to pyrolyze the matrix precursor and burnout the pore former so that the shaped preform comprises the unidirectional arrays of fiber tows and a porous matrix having a monomodal pore size distribution, and subjecting the cured shaped preform to chemical vapor infiltration to densify the porous matrix so that the ceramic matrix composite article has a fiber volume fraction between about 15 percent and about 35 percent.

Abstract: Methods for preparing ceramic matrix composites using melt infiltration and chemical vapor infiltration are provided as well as the resulting ceramic matrix composites. The methods and products include the incorporation of sacrificial fibers to provide improved infiltration of the fluid infiltrant. The sacrificial fibers are removed, such as decomposed during pyrolysis, resulting in the formation of regular and elongate channels throughout the ceramic matrix composite. Infiltration of the fluid infiltrant can then take place using the elongate channels resulting in improved density and an improved ceramic matrix composite product.

Abstract: Methods for preparing ceramic products using liquid infusion technology and products formed from the same are provided. The methods and products include the incorporation of a particulate material and binder between ceramic fibers such that the fibers may be properly spaced during formation of the ceramic product. Ceramic matrix composite products can thereby be provided using near net shaping methods.
