A new type of polymeric composite material spur gear was developed and fabricated using low cost Portland pozzolana cement (PPC) particles as filler into the polypropylene (PP) matrix. PP granules were mixed with PPC particles and an injection-molding process was followed to manufacture the thermoplastic composite gear. Several experiments were conducted with different percentages of PPC particles with the PP to optimize the gear material (cement filled poly-propylene composite) for fabrication. Tensile tests were conducted and the morphological studies of the fractured surface of the gear materials were investigated using scanning electron microscopy (SEM) and field emission SEM (FE-SEM). Dynamic mechanical analysis (DMA) was carried out and viscoelastic properties of the gear materials were studied with varying temperature. Further, extensive experimental studies were carried out to evaluate the performance of the gear tooth under loading conditions. The experimental results validate the suitability of the proposed non-metallic spur gear for low cost industrial applications.
