Abstract Hybrid natural fibre reinforced polymer composites have emerged as an eco-friendly alternative to conventional structural materials due to their low cost and high strength-to-weight ratio. It is evident from the literature that polymer composites have found their place in tribological applications too. Therefore, in this research work, hybrid abaca–epoxy composites were fabricated using hand layup technique with red mud as filler. The influence of wt. % of abaca (A), wt. % of red mud (B) and particle size of red mud (C) on sliding wear of hybrid composite is established using response surface method (RSM). RSM also yields a mathematical model for optimization of sliding wear of hybrid composites. Composite with optimum values of A, B and C was found to be most suited for minimum sliding wear of hybrid composites. Further, on the basis of experimental data, a fuzzy logic model is also framed for the prediction of sliding wear of hybrid composites. Nine test case experiments were performed to validate the developed fuzzy model. It was observed from the results that developed fuzzy model can predict the sliding wear of hybrid composites with an accuracy of 87%.

1 Introduction Natural fibre reinforced polymer composites have been used as an alternative to conventional metallic components in many structural applications, especially in sliding components. Use of polymer composites in sliding parts causes wear due to relative motion between the surface of composite and counterpart. It is also reported that [1] 23% of the energy is consumed only because of relative motion and contact between the components in the world. Polymer composites are used in conventional components in mechanical engineering applications like sliding components in textile industries, bushes of filament wound, cages of ball bearing in dental turbine, hybrid bushing in diesel fuel injection (FI) pumps, etc. Therefore, it becomes necessary to investigate the wear performance of polymer composites before their use in any application. Study and analysis of wear behaviour of polymer composites could help in reduction in friction, thereby reducing the consumption of energy in a process. Reduction

in friction between two or more surfaces also reduces the loss of material (resources). In case of power transmission, low friction between the moving parts increases the net power and enhances the performance. A study based on wear of polymer surface
