Numerical and Experimental Assessment Of Water Absorption of Red Mud-An Industrial Waste Reinforced Sisal/Polyester Hybrid Polymer Composite

The fundamental point of the investigation is to examine the water absorption qualities of highly alkaline red mud (a waste created during the production of alumina) reinforced sisal/polyester hybrid composite. Composites are fabricated at a different percentage of red mud (0, 10, 20 and 30%) utilizing the compression moulding process. Manufactured composites are inspected for water absorption qualities. Water absorption test is done using three unique waters, such as ocean water, ordinary water and distilled water. Redmud inclusion decreased the water absorption of the composites but the increment in redmud reinforcement increases the water absorption. The water absorption behavior of the composite is explored with the numerical model—Fick’s law of diffusion. The water absorption model was found to follow the Fickian behavior for each of the three water used. The composites are analyzed through Scanning electron microscopy (SEM) for understanding the surface failure and fiber damage.
