摘要:
The present invention relates to the friction material for the use of disc brake pads and brake shoes for automotive brake devices, and an object of the present invention is to provide the friction material with sufficiently stable braking force and sufficient mechanical strength. In the friction material without a metal or a metal alloy, the friction material includes the plate-like titanate with average particle diameter of 10 to 50 μm and the hydrous magnesium silicate. An amount of the plate-like titanate and the hydrous magnesium silicate is 20 to 30 volume percent relative to the total amount of the friction material, and the volume ratio of the plate-like titanate and the hydrous magnesium silicate is 12:1 to 5:1. Also, the average particle diameter of the plate-like titanate is 20 to 40 μm, and the plate-like titanate is preferably potassium hexatitanate.
