The composites comprising ceramic<br>particulates such as Silicon carbide, Boron carbide of 1-30 micron size as reinforcement and phenolic resin<br>as matrix carbon precursor were prepared by compaction method followed by carbonization to 1000 °C<br>in inert atmosphere. Experimental results indicate that carbonization results in decrease in thickness and<br>weight, the amount of reduction increasing with addition of carbon fibers results in compact high density<br>composites. Composites comprising of 10 wt. % fibers exhibited maximum hardness, compressive strength<br>and density after carbonization. Tribological properties of the composites were evaluated against Cr6 ball<br>using a pin-on-disc Tribometer with different linear speed, sliding distance and load conditions. It was found<br>that the composites filled with lower amount of carbon fibers showed relatively higher friction coefficient<br>value. Also, it was noted that friction coefficient increases with increase in the applied load (1N, 2N and 5N)<br>and linear speed.</p> ER -
