SISTEMA AUTOMATICO E INTEGRADO PARA LA RECUPERACION DE LA FIBRA E INERTIZACION DE RESINA DE LA FIBRA DE CARBONO PREIMPREGNADA

Integrated process of recovering carbon fiber from prepreg carbon fabric or tape. The process allows the recovery on the one hand of carbon fiber with a practically negligible resin content, and on the other hand of the resin of the polymerized fabric; that is, in the form of inert waste. The process is based on eliminating the partially polymerized resin with a simple process energetically. The process is based on applying heat to decrease the viscosity of the resin; and pressure to make the resin flow. At the end of the process, the polymerized resin and the recycled fiber are separated. In order to achieve a more thorough removal of the resin the process ends with a cleaning with solvent such as acetone. The process is applicable in those cases where the material has expired but the resin has undergone little polymerization so that it can flow when it is overheated and when applying light pressure. In those cases where a more thorough removal of the resin is required, the system allows the coupling of a washing unit with solvent such as acetone.
