Abstract
A gas turbine engine static vane includes a radially outer platform, a radially inner platform, and an airfoil extending between a leading edge and a trailing edge, and having a suction side and a pressure side. The radially inner and outer platforms and the airfoil all are formed of ceramic matrix composite plies. There are an outer platform fillet and an inlet platform fillet merging the airfoil into the radially outer platform and the radially inner platform and along each of the pressure side and the suction side. The fillets are formed with radially outer ply layers extending from the radially outer platform, through the airfoil, and to the radially inner platform, and radially inner ply layers extending from the radially outer platform, through the airfoil, and to the radially inner platform. The radially outer ply layers and the radially inner ply layers do not cover the entirety of the outer platform, the inner platform or the airfoil. They have edges which overlap each other such that the radially outer ply layers and radially inner ply layers include layers of different shapes. A gas turbine engine and a method are also disclosed.
