A1
Abstract:
[Problem] To provide a friction material having sufficient and stable braking power and mechanical strength, for use in disk brake pads and brake shoes in automotive braking apparatuses. [Solution] A friction material not containing single metal elements or alloys, wherein the friction material contains planar titanate having an average grain diameter of 10 to 50 μm and hydrous magnesium silicate to a combined total of 20 to 30% by volume of the total weight of the friction material, and the volume ratio of the planar titanate and hydrous magnesium silicate is from 12:1 to 5:1. It is also desirable that the average grain diameter of the planar titanate be from 20 to 40 μm and that the planar titanate be potassium hexatitanate.
