Tribological properties of fiber reinforced phenolic composites under sliding condition

In this work, the tribological performance of aramid-lapinus fiber combination reinforced phenolic-based automotive brake friction composites was investigated using a pin-on-disc machine. Wear in terms of weight loss and coefficient of friction were determined as a function of applied load (80, 120, 160, and 200 N), sliding velocity (1.67, 3.34, 5.01, and 6.68 m/s) at a fixed sliding distance of 4000 m. The experimental results revealed that with increased applied load, the wear of the composites was increase while the coefficient of friction was found to decrease. On the other hand, higher wear was recorded with increased sliding velocity, while the coefficient of friction decreased after attaining a peak at 5.01 m/s. The lower aramid fiber and higher lapinus fiber combination resulted in increased friction performance, while an excellent wear performance was recorded for the composites having lower lapinus and higher aramid fiber as reinforcement.
