Abstract
A turbine blade of ceramic matrix composite material construction adapted for use in a gas turbine engine is disclosed. The turbine blade includes a root, an airfoil, and a platform. The root is adapted to attach the turbine blade to a disk. The airfoil is shaped to interact with hot gasses moving through the gas path of a gas turbine engine and cause rotation of the turbine blade when the turbine blade is used in a gas turbine engine. The platform has an attachment side facing the root and a gas path side facing the airfoil. The platform is arranged between the root and the airfoil and shaped to extend outwardly from the root and the airfoil in order to block migration of gasses from the gas path toward the root when the turbine blade is used in a gas turbine engine.
