Method of producing tooling for resin transfer molding

1. A method of producing tooling for molding a part by resin transfer molding, the method comprising:

producing a model of the part;

producing a countermold with an outside surface presenting an indentation complementary to a first side of the model;

placing the model in the indentation of the countermold;

draping a plurality of superposed textile layers that are impregnated with thermosetting resin on the model and on the outside surface of the countermold to shape a first half-shell;

curing the first half-shell;

separating the countermold from the model and from the first half-shell;

draping a plurality of superposed textile layers on the first half-shell and the first side of the model, to shape a second half-shell; and

curing the second half-shell.

2. A method according to claim 1 , wherein each half-shell presents at least one orifice in alignment with a corresponding orifice in the other half-shell for passing a device for clamping the first half-shell against the second half-shell.

3. A method according to claim 2 , wherein the model is produced by a rapid prototyping method.

4. A method according to claim 1 , further comprising:

casting a hardenable fluid material into concave rear faces of the first and second half-shells; and

hardening the hardenable fluid material in the concave rear faces.

5. A method according to claim 4 , wherein the hardenable fluid material includes thermally conductive particles.

6. A method according to claim 4 , wherein the hardenable fluid material is concrete.

7. A method according to claim 1 , wherein the textile layers comprise carbon fibers.

8. A method according to claim 1 , wherein the textile layers are impregnated with thermosetting resin before draping.
