Recycling Plastic Scrap in SRIM Composites
The objective of this paper will be to review a novel recycle process involving Structural Reaction Injection Molding(SRIM) which enables a variety of coarsely ground plastic recycle materials to be incorporated into the molded part. What makes this approach novel, is that flexural modulus of the fabricated parts are actually increased when the recycled granulate is employed in the part. This paper will present data for the recycle of a variety of automotive parts, including painted fascia, door skins, covered interior door panels, armrests and instrument panels along with composite bumper beams into the SRIM recycle core process. Resulting part economics will be reviewed along with potential applications to utilize this technology.
