PURPOSE:To improve the friction and abrasion characteristics of a friction material to be used as a sliding part of a braking apparatus of automobile, etc. CONSTITUTION:A friction material is produced by bonding and forming base fibers with a resin binder. In this process, 3-50wt.% of polycrystalline fiber having composite phase consisting of potassium hexatitanate crystal and titania crystal is compounded as the base fiber. The friction face is imparted with high friction coefficient and abrasion resistance over a wide temperature range from low temperature to high temperature owing to the high heat-resistance, shearing strength and abrasion resistance of the base fiber. |
