With a history of nearly 200 years, polymer processing and compounding is constantly changing to fit the material science needs of the era. Exposure of undergraduate students to the technology and practices used in industry today in a lab setting would create new opportunities for experiential learning and growth. The objective was to set up a 0.75”, 25 L/D Thermo Haake single screw extruder for lab use and run trials of material in a single screw extruder to set up a basis for experiments. Trials were run of co-polyester resin through a single screw extruder with carbon fiber additives varying …

Polyethylene terephthalate (PET) appears in daily life in many forms, the most common being disposable soft drink bottling. To deal with the ever-growing quantitity of disposed PET (both in landfills and environment), a waste plan revolving around depolymerization should be implemented. Specifically, the potential of PET depolymerization through aminolysis into useful, low molecular weight monomers will be explored with the end goal of producing a 3D printing filament and analyzing economic feasibility.
