In this study, the effect of using nanocellulose prepared from waste paper on the wear rate of friction materials used in car brake pads is investigated. An important part of the formulation of friction materials used in brake pads is reinforcing fibers, which in fact plays the role of the skeleton of the material. Different fibers are used in brake pads, such as iron fibers, rock fibers, glass fibers, etc. One of the most cost-effective fibers used in brake pads is cellulose fibers. Although cellulose fibers reduce the hardness of the pad and this is a grant, but they increase the wear rate. In this research, the possibility of using nanocellulos as alternative to cellulose fibers to improve the wear rate in the brake pad was investigated. The pads, which made by completely industrial method, were subjected to standard tests and their wear rate was measured in the wear and friction test concerning to the amount of mass reduction. The results show a 40% improvement in the wear rate of the brake pads using nanocellulose instead of commercial cellulose.
