| description | The invention relates to a method for manufacturing a two-component blade for a gas turbine engine, which comprises consecutively obtaining a blade profile (24) made of ceramic material comprising a hole passing through the blade profile from one side to the other in the lengthwise direction in order to form a longitudinal channel (28) opening into an upper recess (26a), positioning and holding a blade profile in a mould (30) so as to form a lower recess (26b) communicating with the channel (28) of the blade profile, pouring molten metal into the blade profile so as to fill the upper and lower recesses and the channel that connects same, and cooling the metal such that the contraction of the cooled metal in the upper and lower recesses causes compressive pre-stressing of the ceramic of the blade profile.
