Method for producing a turbine blade made from ceramic matrix composite material, used for a turbine blade made from ceramic matrix composite material and the turbine blade made of ceramic composite material.

摘要

There are a method (100) for producing a turbine blade (115) of ceramic matrix composite material, an insert (107) for a turbine blade (115) of ceramic matrix composite material and a turbine blade (115) discloses ceramic matrix composite. The method (100) includes providing a vane preform (103) having a dovetail cavity (101), wherein the dovetail cavity (101) is of a dovetail shank (105) of the vane preform (103) enclosed, positioning an insert within the dovetail cavity (101 ), then forming the turbine blade (115) of ceramic matrix composite material in a furnace. The insert (107) has a geometry which is adapted so as to be within a dovetail cavity (101) of the turbine blade (115) of ceramic matrix composite material, a vane preform (103) or used by both. The insert (107) is a foam material or a plurality of ceramic matrix composite material layers. The turbine blade (115) of ceramic matrix composite material has a dovetail shank (105) and a dovetail cavity (101), which is enclosed by the dovetail shank (105). The dovetail cavity (105) is constructed and arranged for receiving an insert (107).
