Abstract

Official abstract text for this publication.

A friction material including two or more kinds of titanates and a ceramic fiber. The friction material includes no copper component. The two or more kinds of titanates may optionally include two or more kinds of alkali metal titanates, or the two or more kinds of titanates may optionally include an alkaline earth metal-alkali metal titanate and an alkali metal titanate.

First claim

Opening claim text (preview).

The invention claimed is: 1. A friction material comprising: two or more kinds of titanates; and a ceramic fiber, wherein the friction material comprises no copper component, wherein the two or more kinds of titanates comprise an alkaline earth metal-alkali metal titanate and an alkali metal titanate, and wherein the ceramic fiber has a fiber diameter of 0.1 to 10 μm, a fiber length of 1 to 1000 μm, and a shot content of 0.1 to 70% by mass. 2. The friction material according to claim 1 , wherein the two or more kinds of titanates further comprise magnesium potassium titanate and potassium titanate. 3. The friction material according to claim 1 , wherein a content of the two or more kinds of titanates in the friction material is from 3 to 40% by volume in total. 4. The friction material according to claim 1 , wherein a content of the ceramic fiber in the friction material is from 1 to 6% by volume. 5. A friction material comprising: two or more kinds of titanates; and a ceramic fiber, wherein the friction material comprises no copper component, wherein the two or more kinds of titanates comprise lithium potassium titanate and an alkali metal titanate, and wherein the ceramic fiber has a fiber diameter of 0.1 to 10 μm, a fiber length of 1 to 1000 μm, and a shot content of 0.1 to 70% by mass. 6. The friction material according to claim 5 , wherein a content of the two or more kinds of titanates in the friction material is from 3 to 40% by volume in total. 7. The friction material according to claim 5 , wherein a content of the ceramic fiber in the friction material is from 1 to 6% by volume. 8. A friction material comprising: two or more kinds of titanates; and a ceramic fiber, wherein the friction material comprises no copper component, wherein the two or more kinds of titanates comprise lithium potassium titanate and potassium titanate, and wherein the ceramic fiber has a fiber diameter of 0.1 to 10 μm, a fiber length of 1 to 1000 μm, and a shot content of 0.1 to 70% by mass. 9. The friction material according to claim 8 , wherein a content of the two or more kinds of titanates in the friction material is from 3 to 40% by volume in total. 10. The friction material according to claim 8 , wherein a content of the ceramic fiber in the friction material is from 1 to 6% by volume.
