Abstract:

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°C 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°C 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°C showed minimum wear rates of 1.03 × 10-5 N/m and 0.98 × 10-5 N/m at 5N load respectively. The wear behaviours of 9500C carbonized ash were better than those of 850°C and 900°C carbonized ash due to the degree of alteration in the structure of the silica.
