Despite comprising of recyclable polymers, thermoplastic waste has made international headlines as a major source of environmental pollution. For this thesis, multiple thermoplastic constituents were used to create different sets of sandwich panels that were tested and studied rigorously to determine whether a relevant structural application can arise from the current thermoplastic waste. Polyethylene Terephthalate (PET) was used in fibre form to create a new fiber reinforced polymer (FRP) composite used as the facing material for the sandwich panels. Polypropylene (PP) was used in the form of honeycomb as a core material to one set of sandwich panels. Another set of sandwich panels was made from recycled PET foam core, which was obtained from 100% post-consumer PET bottles. Mechanical properties of the sandwich structures and their different components were obtained experimentally and analytically.enPlastic wasteSustainabilitySandwich panelsFibre reinforced polymerCompositesThesis
