%X The effect of carbonization temperatures on wear rate behaviours of different volume fractions of rice husk ash epoxy composite was studied. Rice husk ash carbonized at 850, 900, and 950¡ãC were reinforced in epoxy resin. Rice husk ash epoxy composite containing 10%, 20%, 30% and 40% rice husk ash was synthesized using manual stirring method and specimens were prepared for wear studies. Dry wear behaviour of sample was studied against abrasive paper using a pin-on-disc machine. Wear rate and specific wear rate behaviours of different samples have shown near uniform behaviour. The 950¡ãC carbonized ash showed steady wear rate and specific wear rate behavior for all ash contents. The composites with 30% and 40% ash carbonized at 950¡ãC showed minimum wear rates of 1.03 ¡Á 10-5 N/m and 0.98 ¡Á 10-5 N/m at 5N load respectively. The wear behaviours of 9500C carbonized ash were better than those of 850¡ãC and 900¡ãC carbonized ash due to the degree of alteration in the structure of the silica.
