PROBLEM TO BE SOLVED: To provide a non-asbestos friction material composition capable of providing an abrasion material which is excellent in abrasion resistance at high temperature even when the content of copper is low and in which the occurrence of metal catch is less, and to provided an abrasion material and an abrasion member each obtained using the non-asbestos friction material composition.SOLUTION: The non-asbestos friction material composition is provided in which copper content is 5 mass% or less as a copper element, content of metal fibers other than copper and copper alloy is 0.5 mass% or less, titanic acid content is 13 to 24 mass%, zirconium oxide content is 5 to 30 mass% and content of zirconium oxide having a particle diameter of over 30 μm is 1.0 mass% or less, and in which the titanic acid salt consists of at least one of titanic acid lithium potassium with a scaly, columnar or tabular shape or titanic acid magnesium potassium with a scaly, columnar or tabular shape or titanic acid potassium with a columnar or tabular shape.SELECTED DRAWING: None |
