Abstract: A portable machine for cutting pieces of composite material, having a compression module which includes one or more top rollers and two or more bottom rollers, wherein the top rollers are coupled to a mechanism configured to vertically move said top rollers, thereby compressing the pieces to be cut, wherein at least one top roller (4) is vertically offset with respect to a bottom roller adjacent to the same, the offset angle being comprised between 45°±15°, in such a way that the piece of composite material is compressed by the rollers in a direction that is substantially perpendicular to the direction of the fibers, fracturing, delaminating and breaking the fibers before the cut is made in a diamond wire cutting module.

Abstract: A method and installation for the thermal degradation of composite materials for recycling, includes a first rotary cylindrical furnace configured to receive a load of composite material through an inlet opening thereof, wherein said first furnace comprises an internal spiral equipped with an open configuration in a central portion of said internal spiral, wherein said first furnace is sealed and is configured to maintain a controlled oxygen atmosphere in operation of between 2% and 8% and to heat up to a temperature between 200° and 600° C., and a second rotary cylindrical furnace suited to receive the load of composite material from the first furnace continuously without interruption, and configured to maintain a controlled oxygen atmosphere of between 8% to 20% and heat up to a temperature between 200° and 600° C.
