1. A shroud segment comprising:
a forward radial wall comprising a ceramic matrix composite including reinforcing fibers embedded in a matrix;
an aft radial wall comprising a ceramic matrix composite including reinforcing fibers embedded in a matrix;
at least one interlocking subcomponent comprising a ceramic matrix composite including reinforcing fibers embedded in a matrix, wherein the at least one interlocking subcomponent comprises a flowpath comprising one or more slots extending between axially extending opposed edges of the flowpath; and
an interlocking mechanical joint joining each of the forward radial wall and the aft radial wall to the at least one interlocking subcomponent to form the shroud segment.
