Abstract
This invention discloses a shear assisted processing (SAP) method for producing plastics rods and discs from pellets or waste. During a single-step manufacturing process, shear deformation is introduced to heat and soften the precursor so it can be deformed, mixed, consolidated, and then extruded as solid wire. Toolings, processing procedures and parameters were developed for processing different types of plastics. 2.5mm diameter wires were recycled from polypropylene (PP), polyethylene (PE), a mixture of PP and PE, carbon fiber reinforced plastic (CFRP) and post-consumer plastic bags, respectively. DSC shows that the wires made from mixed plastics have good homogeneity. Tensile test results proved the recycled plastics had retained up to 90% strength of raw materials.
