| Abstract: |
| New non-fibre reinforcing friction materials for auto brake toughened with powdered NBR，SBR and NR respectively have been investigated.The results show that the material toughened with powdered NR is the most effective，while the powdered NR can' t be used in this kind of material.For the non-fibre reinforcing material using 10 parts of powdered NR and 10 parts of phenolic resin as the matrix，the properties，such as friction coefficient (0.39一O.44)，wear rate (0.108m33·J-1)，impact strength (3.160J·m-1)and thermal fade resistance are better than those specified in the national standard.The analysis to the surface of the material shows that the ploughing-cutting is one of the important reasons for wear. |
