Effect of Bagasse and Chicken Feather Fiber Hybridization on Thermo-Mechanical and Water Absorption Properties of Hybrid Polypropylene Composites

Hybrid composite refers incorporation of more than one type of fiber in a single matrix that demonstrates striking outcomes through combination of properties. Employing plant and animal-based biodegradable resources as reinforcement in polymeric composites has undeniable advantages on synthetic fibers including low cost, renewability, biodegradability, low energy consumption, easy and safe handling, and supports their applicability in a variety of fields. In the present research, bagasse and chicken feather fiber reinforced hybrid polypropylene composites were prepared by hot pressing technique. Bagasse is agricultural waste, while chicken feather can also be collected from poultry industry waste. Composite samples were created for characterization by altering the weight percentage of fibers in the composite at 5, 10 and 15. For mechanical characterization, tensile, flexural, hardness, and impact tests were performed where the best set of properties was encountered with fiber loading of 5%. Water absorption tests and thermogravimetric analysis were also carried out. The water absorption test exhibited minimum water absorbing affinity with the lowest fiber content at 5%. Adding more fiber enhanced thermal stability in the composite.
