Abstract: A curing mold for manufacturing a turbomachine component is made of composite material from a preform, including: a first and a second body defining an air gap receiving the preform; at least one primary channel arranged in the first and/or the second body; an injection member of a pressurized fluid in the primary channels; at least one secondary channel, in which a piston slides, which delimits, on the one hand, a first chamber in communication with the or a primary channel and, on the other hand, a second chamber in communication with the air gap, and which is designed to compress thermosetting resin which has entered the second chamber from the preform in the air gap, so as to put the preform under hydrostatic pressure.

Abstract: A curing mold for manufacturing a turbomachine part made of composite material from a preform produced by draping pre-impregnated materials includes: a first body and a second body designed to be attached to each other and jointly defining a fixed air gap for receiving the preform and itself including a molding part of complementary shape with the part to be manufactured and intended to receive a portion to be molded of the preform, and at least one additional part located in a peripheral space of the air gap and intended to receive an additional portion forming an edge of the preform; a heating member designed to heat the preform in the air gap to a first temperature; at least one inflatable bladder housed in the first or second body, facing an additional part of the air gap; a member for injecting a pressurized fluid inside the bladder(s).

Abstract: The invention relates to an external composite housing for a compressor of an axial turbomachine, the housing having a generally circular wall with a matrix and fiber reinforcement. The housing includes a circular wall with an internal surface having a continuous curve around the circumference of the wall. The wall includes flat facets that are flush with the internal curved surface of the wall. The facets are arranged in annular rows to receive annular rows of stator vanes. The facets are flat disks against which the vanes bear to optimize the orientation of the vanes, while reducing the concentrations of mechanical stresses at the platform/wall interfaces.
