Effect of Nano-sea shells Reinforcement on Friction and Wear Properties of Aramid Fiber Friction Materials

Friction materials play an important role for controlling the vehicle at various operating speeds and pressures. The coefficient of friction and wear generated between disk and pad play a vital role for controlling the vehicle. In this work, an attempt was made to improve the coefficient of friction by addition of nano-sea shell powder particles as an abrasive medium. The sea shell particles are made to crush to a finer size using a ball milling process. Aramid fiber is selected as the base fiber for giving strength to the composite. The surface of aramid fiber was modified with functionalized multi-walled carbon nano-tubes (F-MWCNT) for reducing the chemical inertness and improving the bonding performance. Three composite sheets (AFS-I, AFS-II, and AFS-III) are fabricated using hand layup method by keeping the polymer matrix and ingredients as constant and varying the contents of aramid fiber and nano-sea shells. The brake pad samples were cut for evaluating the performance using a self-made brake test rig. The test was performed at four pressures, temperatures, braking numbers and disk speeds using Taguchi design of experiments. MATLAB software with artificial neural network (ANN) was used for validation of results. SEM and AFM analyses are also performed on all the samples. The final results conclude that AFS-II composite friction material containing aramid fiber 9 wt%, nano-sea shells powder 6 wt%, and F-MWCNT 0.2 wt% along with remaining ingredients exhibited superior properties in terms of coefficient of friction and wear.
