Abstract
The present invention concerns a method for producing a mould intended for moulding a composite part, in particular intended for the wind power, nautical or aeronautical technical fields. The mould is made from a composite material. Moreover, the heat transfer fluid circuit (2) that said mould comprises is made during the mould production process. The circuit (2) comprises at least one tube made from a material with a low thermal expansion coefficient, advantageously close to that of the composite material.
Claims8
A method for manufacturing a molding tool intended for molding a part made of composite material, comprising:
- a) providing a support is provided;
- b) disposing on the support a first stacking of reinforcing fibers which are possibly impregnated with a thermosetting or a thermoplastic resin;
- c) disposing on the first stacking of reinforcing fibers a circuit comprising at least one tube made of a material of low thermal expansion coefficient, said circuit having the shape of a heat carrying fluid circuit adapted to the molding tool;
- d) disposing on the circuit a second stacking of reinforcing fibers which are possibly impregnated with a thermosetting or a thermoplastic resin;
- e) compressing the set constituted by the first stacking of reinforcing fibers, the circuit, the second stacking of reinforcing fibers and where appropriate when the reinforcing fibers are not impregnated with a thermoplastic or a thermosetting resin, a thermoplastic or a thermosetting resin is infused;
- f) carrying out a thermal cycle being designed in such a manner as to harden the thermosetting or the thermoplastic resin in order to obtain a molded shape;
- and
- g) stripping the molded shape obtained from step f).
