PURPOSE: A novel recycling system and method for waste GMT bumper backbeam is provided to perform the extrusion of a mixture by adding homo polypropylene, TAFMER, and maleic anhydride-grafted polypropylene. CONSTITUTION: 60 weight% of waste GMT(Glass Mat Thermoplastics) grinded material, 25 weight% of homo polypropylene, 5 weight% of tafmer, and 5 weight% of maleic anhydride-grafted polypropylene. The mixture is injected into a primary extruder of a waste GMT bumper backbeam reproduction apparatus. The extrusion of the mixture is performed by an extruding screw of 200mm diameter of the primary extruder. The secondary extrusion of the mixture is performed through a secondary extruder. A recycling pellet is manufactured through the cutting of the processed mixture.
