Addition of red mud (an industrial waste) in to sisal fiber, banana fiber reinforced
unsaturated polyester (USP) is discussed in this study. Red mud is the caustic insoluble waste
residue generated during the alumina production from bauxite. Composites were fabricated
separately with sisal/USP, banana/USP and each of them was filled with red mud also through
compression molding process. Static mechanical tests like tensile, flexural, impact were
conducted as per ASTM. Experimental results show that the addition of red mud promotes a
marginal increase in the mechanical strength.
