This present article describes the effect of red mud filler on wear responses of banana fiber reinforced unsaturated polyester composites. Banana fiber treated NaOH and untreated were taken for the wear studies as reinforcement along with unsaturated polyester and red mud. Red mud, polyester and banana fiber of different weight proportions were taken by keeping the fiber length as fixed (30 mm) which is optimal ones. Compression molding technique is used for preparing the specimens. Wear studies were carried out by using a pinon- disc wear tester for the specimens prepared as per ASTM standard. Taguchi design of experiments with L9 orthogonal array is used to optimize the parameter with respect to sliding velocity, load and sliding distance.
