Abstract: A process for recycling a material containing high-tenacity fibers impregnated with a resin matrix includes introducing the material containing the high-tenacity fibers and the resin matrix into a hammer mill having a shaft mounted with at least three series or stages of hammers and a substantially cylindrical sieve disposed substantially concentrically around the shaft, milling the material for a time sufficient to grind at least about 50%, and preferably at least about 80%, of the resin into small particles, and separating the small resin particles from the fibers by means of the sieve. This process allows a very high degree of separation and does not require additional process steps like cryogenical chilling.
