Abstract
A method for producing a part, in particular a part made of composite material, in particular for a turbomachine, including at least: a step of producing a preform, during which a fibrous preform intended to form an outer skin of the part is produced; a step of producing a core, during which a rigid core, in particular a hollow rigid core, intended to form a framework of the part is produced; an insertion step, during which the rigid core is inserted into the fibrous preform, an injection step, during which a matrix is injected into the fibrous preform; and a heat-treatment step, during which polymerisation of the matrix is carried out.
Claims16
A method for producing a part, made of composite material, for a turbomachine, comprising at least:
- a step of producing a preform, during which a fibrous preform intended to form an outer skin of the part is produced;
- a step of producing a core, during which a hollow rigid core, intended to form a framework of the part is produced, the hollow rigid core comprising an inner cavity subdivided into a plurality of cavities by stiffeners, and further comprising an inner recess defining a space intended to receive a spar;
- an insertion step, during which the hollow rigid core is inserted into the fibrous preform and during which a spar is inserted into the inner recess of the hollow rigid core,
- an injection step, during which a matrix is injected into the fibrous preform;
- and
- a heat-treatment step, during which polymerisation of the matrix is carried out.
