1. A ceramic matrix composite (CMC) component, comprising:
a plurality of CMC plies comprising, at least, a first CMC ply and a second CMC ply stacked together to form a laminate structure,
the first CMC ply being formed from a CMC material reinforced with a fiber material having a first fiber orientation, the second CMC ply being formed from the CMC material reinforced with the fiber material having a second fiber orientation,
the first and second fiber orientations being arranged in a cross-ply pattern in a plane of the laminate structure, the laminate structure comprising at least one edge; and
at least one end cap ply covering at least a portion of the at least one edge of the laminate structure, the at least one end cap ply being formed of the CMC material reinforced with the fiber material having the first fiber orientation or the second fiber orientation,
wherein at least a portion of a plane of the at least one end cap ply is perpendicular to the plane of the laminate structure.
