Abstract

As part of on-going studies on the manufacturing of re-engineered materials from waste streams, a modified cyclic `intrusion' process for the production of thick-walled parts was developed and analyzed. The experimental set-up involves the use of a fully instrumented single screw extruder for measuring parameters such as melt temperature and pressure, as a function of time. Initial experiments with unfilled and foamed thermoplastics were followed by extruding, into a rectangular mold, polyethylene based polymer blends containing as filler a mostly particulate fraction of automotive shredder residue (ASR). Process related experimental data were compared with predictions from a conventional injection mold cavity flow analysis software. Modulus values of the products were compared with predictions from composite theory. In most cases, relatively good agreement was observed between experimental and predicted values.
