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 unitary ceramic component is provided that includes a first ceramic component; a second ceramic component; and a series-hybrid joint coupling the first ceramic component to the second ceramic component. The series-hybrid joint includes a first bonding interface coupling the first ceramic component and the second ceramic component and a second bonding interface coupling the first ceramic component and the second ceramic component. The first bonding interface exhibits properties that are different from the second bonding interface.

Abstract: Methods for forming a unitary ceramic component are provided. The method may include: positioning a braze reactant layer in a contact area between a first densified ceramic component and a second densified ceramic component; positioning a pack material around at least a portion of the first densified ceramic component or the second densified ceramic component; positioning at least one infiltrate source in fluid communication with the braze reactant layer; and thereafter, heating the at least one infiltrate source, the pack material, the first densified ceramic component, and the second densified ceramic component to a braze temperature that is at or above a melting point of at least one phase of the infiltrate composition such that at least one phase of infiltrate composition melts and flows into the braze reactant layer and reacts with a ceramic precursor compound therein to form a ceramic material.

Abstract: Composite components and methods for adding a composite material to a composite component are provided. For example, a method comprises positioning a composite material segment against the composite component to form a component layup; applying an insulating material around at least a portion of the component layup to form an insulated layup; and densifying the insulated layup, where the composite component was previously densified before positioning the composite material segment against the composite component. In some embodiments, the composite material is ceramic matrix composite (CMC) and the composite material segment is a plurality of CMC plies. The composite component may be a CMC gas turbine engine component that comprises an original CMC component and a new CMC material segment joined to the original CMC component through the transfer of silicon between the original CMC component and the new CMC material segment during melt infiltration.
