Abstract: A process of producing a ceramic matrix composite component. The process includes positioning core plies on a mandrel. At least partially rigidizing the core plies to form a preform ceramic matrix composite arrangement defining a tip cavity and a hollow region. Ceramic matrix composite tip plies are positioned on the preform ceramic matrix composite arrangement and within the tip cavity. The ceramic matrix composite tip plies are densified to form a tip region of the composite component.
