Polymer hybrid-reinforced composites are extensively used in automobile industries owing to their excellent physical, chemical and mechanical properties. The purpose of this study is to investigate the tribological behavior of three types of friction materials, aramid fiber friction material (AFFM), carbon fiber friction material (CFFM) and hybrid fiber (combination of carbon and aramid) friction materials (HYFFM). The performance of these materials was analyzed using a wear test rig. Functionalized multi-walled carbon nanotubes (F-MWCNT) are grafted on carbon and aramid fibers for improvement of roughness of the fiber surface using chemical route method. A fixed fiber loading of 10wt% for AFFM and CFFM and 10 wt% for HYFFM (7wt% CF and 3 wt% AF) and nano seashells powder was used. The wear test was performed at three loads, speeds and time intervals. The values of wear rate, coefficient of friction and frictional force were noted for three samples. Each sample was analyzed for nine experiments. Topsis analysis was carried for predicting the best experiment. The most influencing parameter for achieving the smaller wear and high coefficient of friction was determined by using Taguchi design. Hybrid fibers combining carbon and aramid are a new combination of friction material exhibiting the lesser wear rate and high coefficient of friction compared to other two types of friction materials. Experiment No 9 having (3wt% AF and 7wt% CF) possesses better performance. The most influencing parameters for HYFFM were observed to be speed followed by load and time.
