| Summary: | 1. Field of the Invention
In a friction material including a fibrous reinforcement, a friction modifier and a binder, no whisker-like potassium titanate fiber is contained, but powdery or flaky potassium titanate with an aspect ratio of not higher than 3 is mixed as a friction component. The diameter of the powdery or flaky potassium titanate is preferably in a range of from 0.05 m to 150 m. In addition, the powdery or flaky potassium titanate is preferably subjected to surface treatment with a silane coupling agent, phenolic resin, or the like. Further, fibrous potassium titanate may be mixed at a volume ratio of not higher than 30% with respect to the powdery or flaky potassium titanate. The fibrous potassium titanate is a by-product when the powdery or flaky potassium titanate is produced and which has a length of not longer than 5 m or a diameter of not smaller than 3 m. |
