Dispositivo para la elaboracion de preforma de componentes reforzadas con fibras de carbono

The invention relates to a device for the preparation of preforms of carbon fiber-reinforced components comprising a preforming mold (2) that can be immobilized on a work bench (14) in an electrically insulated manner, and provided with at least two electrodes (4) in positions in which they contact opposite end areas of the preform (3) to generate a resistive electrical circuit through the carbon fibers (3.1) of the preform (3) and thus activate a binder present in the preform (3) by heating; a leak-tight elastically deformable compacting membrane (5) capable of adapting to the outer geometry of a preform (3) arranged on the mold (2) and assembled in a fixing frame (7) of a compacting device and which can be coupled to a lifting device (1); pneumatic connection means connected to the compacting device (6) to force the membrane (5) to exert a compacting force on the preform (3); at least the parts of the mold (2) which are in contact with the preform (3) and with the electrodes (4) are made of an electrically insulating material.
