Paper-based friction materials have been used for power train in vehicles. The motional property and reliability of vehicles depend on the mechanical properties and strength of paper-based friction materials. Paper-based friction materials are composed of aramid fiber, cellulose fiber, carbon fiber, fillers and resin, and have an extremely complex microstructure. The mechanical properties and strength of paper-based friction materials are affected by constituent materials and a fabrication method. Their effects on the mechanical properties and strength are not fully investigated In addition, an experimental method to evaluate the mechanical properties and strength of paper-based friction materials has not been established. In this study, effects of fibers on in-plane tensile strength and debonding fracture toughness of paper-based friction materials were investigated. Experimental results show that the aramid fibers reduces the in-plane tensile strength but enhances the debonding fracture toughness, the cellulose fibers enhance the in-plane tensile strength but reduces the debonding fracture toughness and the carbon fibers reduces the in-plane tensile strength and the debonding fracture toughness.
