Abstract
Disclosed is a device for preparing preforms of carbon fiber-reinforced components including a preforming mold that can be immobilized on a work bench in an electrically insulated manner, and provided with at least two electrodes in positions in which they contact opposite end areas of the preform to generate a resistive electrical circuit through the carbon fibers to activate a binder present in the preform by heating, a leak-tight elastically deformable compacting membrane capable of adapting to the outer geometry of a preform arranged on the mold, and a pneumatic connection means connected to the compacting device to force the membrane to exert a compacting force on the preform.
