Abstract:
A device for cutting a fibrous preform, for production of a part made of a composite material by injection of resin under vacuum. The device includes a die for receiving the preform, on which a template of outer edges of the part is referenced, a mechanism cutting outer edges of the preform according to the template, and a mechanism for cooling the preform that is suitable for solidifying a liquid forming a substrate for the preform.
