Abstract
A turbine blade of ceramic matrix composite material construction adapted for use in a gas turbine engine includes an airfoil assembly. The airfoil assembly includes an airfoil and at least one reinforcement inset coupled to the airfoil assembly. The reinforcement inset is configured to resist damage to the airfoil assembly due to objects impacting the airfoil assembly.
