Abstract
Official abstract text for this publication.
A friction material contains: at least one kind of a titanate compound having a shape having a plurality of convex portions; and a bio-soluble inorganic fiber. In the titanate compound, a three-dimensional shape of a particle thereof has a plurality of convex portions.
First claim
Opening claim text (preview).
The invention claimed is: 1. A friction material, comprising: at least one kind of a titanate compound having a shape having a plurality of convex portions; and a SiO 2 —MgO—SrO-based bio-soluble inorganic fiber containing silicon dioxide (SiO 2 ), magnesium oxide (MgO) and strontium oxide (SrO) as a chemical component thereof, the bio-soluble inorganic fiber containing shots in an amount of 0.1 to 70% by volume of the bio-soluble inorganic fiber. 2. The friction material according to claim 1 , wherein the bio-soluble inorganic fiber is contained in an amount of 0.5 to 25% by volume. 3. The friction material according to claim 1 , wherein at least one kind of the titanate compound having a shape having a plurality of convex portions is contained in an amount of 2 to 35% by volume. 4. The friction material according to claim 1 , containing no copper element. 5. The friction material according to claim 2 , wherein at least one kind of the titanate compound having a shape having a plurality of convex portions is contained in an amount of 2 to 35% by volume.
