Carbon fiber reinforced friction material is formulated by grafting MWCNT-F on its surface. This material combination is investigated in this work by using a wear test apparatus. The surface of CF is chemically inert and hydrophobic in nature and possesses poor bonding strength with polymer matrix. Hence, an attempt is made to improve the bonding behaviour between CF and remaining ingredients. CF surface is modified by grafting multi walled carbon nano tubes functionalized (MWCNT-F) on CF surface. CF content after surface modification is varied in wt% (2%, 3%, 4% and 5%) and mixed with remaining ingredients of friction material. Composite sheets are prepared by using hand layup method. Multi walled Carbon Nano Tubes grafted friction material (MWCRFM), is characterized for SEM. MWCNTs-F on CF surface is observed. Sample specimens are cut from the friction composite sheets and the influence of performance properties like friction, wear, speed, load and time on friction is studied. The behaviour of the samples are also analyzed using regression analysis L9 (3×3) experimental design method for 3 different loads, time periods and speeds. The results reveal that, time and braking pressure plays an important role to control the wear rate and coefficient of friction of the composite. It was also observed that, MWCNT-F grafted on CF specimens for sample M5 (CF 5 wt%) possess less wear rate and high stable coefficient of friction compare to other formulations of materials.
