The friction-resistant sisal fiber/nanoSiO2 phenol formaldehyde resin composites were prepared through compression molding. In order to enhance the bonding between the sisal fiber (SF) and polymer matrix, sisal fibers were treated with different surface modifiers (alkali, coupling agent and borax). The friction and wear properties of the composite materials were investigated with a constant speed (D-SM) tester. The worn surfaces of composites were observed by scanning electron microscope (SEM). The results showed that the adoption of nanoSiO2 phenol formaldehyde resin as matrix resin can solve the heat fade of the friction material. The friction and wear parameters of the treated sisal fiber composites can meet the requirement of standards GB5763-1998. The fiber treatment methods had great influence on the friction and wear properties of the fiber composites. Specifically, the borax treated fiber composites showed low wear rates at different temperatures. The highest friction and wear resistances of sisal fiber composites were reached when the fiber content was 15%. Our data demonstrated that the sisal fiber is an ideal substitute of asbestos for brake pads. |
