Use of bio-composites is gaining acceptance in the engineering world swiftly. However, materials wear out and erode with passage of time. Not much study, however, has been done on this aspect of bio-composites. In this paper, study of tribological behaviour of rice husk-reinforced composites has been done. The effect of rice husk addition has been observed on the wear characteristics of the composite using a pin-on-disc machine. It is seen that the increase in weight percentage of rice husk results in poorer wear characteristics. The SEM micrographs showed improper adhesion between the fibre and the matrix as the reason behind this deterioration in wear strength. Pre-treatment of rice husk with sodium hydroxide improves the adhesion between the matrix and the fibre which is evidently proven by the improvement in wear rate. The increase in wear strength is further corroborated by SEM photographs. It can be concluded that improving the adhesion between the fibre and the matrix by alkali treatment can enhance the working life of the material which can be beneficial in economic and environmental terms.
