【 摘 要 】

The circular economy is emerging as green technology solution for polymer and composite industries. However, the use of circular economy as an industrial practice is still a global challenge. In this article, polypropylene-cotton hybrid composite was developed using different amounts of cotton fibre waste (0, 10, 30, 40 wt%). Scanning electron microscope (SEM), tribometer, Rockwell hardness tester and binocular microscope were used for investigations of composite surface, hardness and coefficient of friction (COF). The mean coefficient of friction values was 0.64, 0.75, 0.88 and 0.94 for pure propylene, 10, 30 and 40% of cotton reinforced composites, respectively. The scanning electron microscopy characterization of hybrid composite revealed the voids, porosity and asperities due to random fibres orientation. The Rockwell hardness value of composites was increased due to rise of fibre fraction. Based on the COF values, hardness and surface characterization, polypropylene-cotton reinforced hybrid composite could be used functionally for thermal and sound applications.
