Abstract:
A method of manufacturing a turbine comprising a plurality of blades disposed between first and second end plates, the blades and the first and second end plates being made of a thermostructural composite material, the method comprising the steps of:a) forming a first part as a single one-piece part from a thermostructural composite material to comprise both the first end plate and the blades, the step of forming the first part further comprising:fabricating a first fiber preform in the form of a plate having outside dimensions that are selected as a function of the outside dimensions of the first part;densifying the first fiber preform at least partially by a matrix so that the first fiber preform is at least consolidated; andmachining the at least partially densified first fiber preform to give it the shape of the first part;b) forming a second part as a single one-piece part from a thermostructural composite material to comprise the second end plate, the step of forming the second part further comprising:fabricating a second fiber preform;densifying the second fiber preform with a matrix; andmachining the second fiber preform to form the second end plate; andc) assembling the turbine by applying the second part against the blades of the first part.
