A gas turbine ring segment () for use in gas turbine engines made from a ceramic matrix composite (CMC) material is disclosed. The ring segment includes a stacked multiplicity of CMC thin-sheet lamellae () each comprising a peripheral surface collectively defining a cross-section profile of the ring segment. The lamellae collectively define a channel () formed in the center thereof for receiving a bow-tie member (). The bow-tie member is disposed in the channel for holding together the stacked lamellae in a through thickness direction, and the in-plane strength of the bow-tie member is perpendicular to the in-plane strength of the lamellae. A stem portion () of the assembly may be further secured with a wrap () of CMC ribbon.
