Abstract: Ceramic matrix composite articles include, for example a first plurality of plies of ceramic fibers in a ceramic matrix defining a first extent, and a local at least one second ply in said ceramic matrix defining a second extent on and/or in said first plurality of plies with the second extent being less than said first extent. The first plurality of plies has a first property, the at least one second ply has at least one second property, and said first property being different from said at least one second property. The different properties may include one or more different mechanical (stress/strain) properties, one or more different thermal conductivity properties, one or more different electrical conductivity properties, one or more different other properties, and combinations thereof.

Abstract: A ceramic matrix composite (CMC) component including a first subcomponent and a second subcomponent. The first component formed of a ceramic matrix composite (CMC) including reinforcing fibers embedded in a matrix and the second CMC subcomponent formed of one of a ceramic matrix composite (CMC) including reinforcing fibers embedded in a matrix or a monolithic ceramic material. The subcomponents further including an interlocking mechanical joint joining the first subcomponent and the second subcomponent to form the composite material component. The interlocking mechanical joint including at least one groove defined in one of the first subcomponent or the second subcomponent and into which a portion of the other of the first subcomponent or the second subcomponent is disposed. A shroud segment is provided formed of the joined first and second subcomponents. Methods are also provided for joining the first and second subcomponents using an interlocking mechanical joint.

Abstract: Ceramic matrix composite articles include, for example a first plurality of plies of ceramic fibers in a ceramic matrix defining a first extent, and a local at least one second ply in said ceramic matrix defining a second extent on and/or in said first plurality of plies with the second extent being less than said first extent. The first plurality of plies has a first property, the at least one second ply has at least one second property, and said first property being different from said at least one second property. The different properties may include one or more different mechanical (stress/strain) properties, one or more different thermal conductivity properties, one or more different electrical conductivity properties, one or more different other properties, and combinations thereof.
