| Abstract: | By using phenol formaldehyde resins modified with nano-SiO2 as matrix,using surface-treated sisal fiber and wollastonite as reinforcement,we prepared the asbestos-free friction material.The friction and wear properties were investigated on constant speed(D-MS) tester.And the abrasion surfaces of composites were observed by scanning electron microscope(SEM).The result shows that all the properties,such as,friction coefficient and wear rate can meet the GB5763-1998 requirement.When the sisal fiber and wollastonite hybrid ratio is 1∶2,the composite has the high mechanical properties,suitable and stable coefficient of friction and relatively low wear rate especially at high temperature. |
