A device for moulding at least one bladed part of a turbomachine, including a base, a mould formed from several parts that are interlocked with each other, this mould being applied to the base and first sealing means being mounted between the mould and the base, a bell-shaped dome mounted on the mould and around the mould, this bell-shaped dome being applied to the base and second sealing means being mounted between the bell-shaped dome and the base, this bell-shaped dome being configured to be held clamped against the base and including inner surfaces cooperating by corner effect with complementary outer surfaces of the mould in order to apply a clamping force on the parts of this mould.

A method of manufacturing a composite component comprises forming a core, surrounding the circumference of the core with a first layer of fabric, applying a second layer of fabric having a different coefficient of thermal expansion from the first layer such that the second layer extends around at least a portion of the circumference of the core and curing the component such that the second layer imparts a compressive or tensile force on the core.

Systems and methods for 4D printing of composites are described herein. A composite layer arrangement is obtained for forming a composite laminate having a substantially flat profile. A plurality of composite layers are deposited according to the composite layer arrangement to form the composite laminate. The composite laminate is activated to produce a curved composite structure.

A device for moulding at least one bladed part of a turbine engine, including a base; a mould formed from a plurality of parts nested inside one another, this mould being applied to the base. A first seal is mounted between the mould and the base; and a bell is mounted on the mould and around the mould, this bell being applied to the base. A second seal is mounted between the bell and the base, this bell being configured to be held tight against the base and having interior surfaces engaging by wedge effect with complementary exterior surfaces of the mould in order to apply a clamping force on the parts of this mould.

Expandable substrates, which are referred to as blanks, are created by compressing thermobonded nonwovens after heating the binder material above its melting temperature, and then cooling the compressed nonwovens so that the binder material hardens and holds the fibers of the nonwoven together in a compressed configuration with stored kinetic energy. A mold for the component to be manufactured can be partially filled with a number of boards (or blanks) in a stacked, vertically, adjacent or even random orientation. Upon application of heat to the boards or blanks or parts in the mold, the binder material is melted so as to allow the nonwoven material to expand in one or more directions, and thereby fill all or part of the mold. Upon cooling, the binder material again hardens, and the molded component is retrieved from the mold.
