Abstract

The present invention relates to a device for recycling carbon fibers (5), which includes two metal rails (1, 2) between which the carbon fibers (5) are intended to be stretched, and a current generator (3), the terminals of which are connected or intended to be connected to the two metal rails (1, 2). The rails (1, 2) form electrodes (1, 2) in short circuit when the carbon fibers (5) are arranged on said rails (1, 2). The generator (3) is suitable for outputting at least one current pulse of a power in the order of or greater than the MW between these two rails (1, 2), which allows the separation of the fibers from their resin. A recycling method implemented with this device is also proposed.

Abstract

The present invention concerns a carbon fibre recycling device (5), which comprises two metal rails (1, 2) between which the carbon fibres (5) are intended to be laid, and a current generator (3) whose terminals are connected or intended to be connected to the two metal rails (1, 2). The rails (1, 2) constitute short-circuited electrodes (1, 2) when the carbon fibres (5) are arranged on said rails (1, 2). The generator (3) is adapted to deliver between these two rails (1, 2) at least one current pulse with a power of the order of or greater than one MW, which allows for the separation between the fibres and their resin. A recycling method to be used with this device is also proposed.

Abstract

A method for reusing material by pulsed power, according to which a series of electrical discharges are generated between at least two electrodes in a reactor receiving an ambient liquid as well as the materials to be reused. The series of said electrical discharges produce, as a result of the energy, the frequency of the electrical discharges, the voltage between the electrodes and the switching time, a mechanical shockwave which propagates over the materials to be processed in the reactor. The ambient liquid is cooled by a continuous or carousel cooling system, to enable the production of nanoparticles.

Abstract

A method and device for reusing materials and/or products by pulsed power according to which a series of electrical discharges are generated between at least two electrodes in a reactor containing an ambient liquid as well as the materials and/or products to be reused. The energy of the electric discharges, the voltage between the electrodes, the switching time and the frequency of the discharges are selected such that said discharges generate electric arcs that pass through the materials and/or products to be reused, and mechanical shock waves that propagate across the materials and/or products to be treated in the reactor. The result is fragmentation, pulverisation, dispersion and separation of the elements that make up the materials and/or products to be reused.
