摘要： There is provided a sintered friction material for railway vehicles that has excellent frictional properties and wear resistance even in a high speed range of 280 km/hour or more. The sintered friction material for railway vehicles is a green compact sintered material containing, in mass%, Cu: 50.0 to 75.0%, graphite: 5.0 to 15.0%, one or more selected from the group consisting of magnesia, zircon sand, silica, zirconia, mullite, and silicon nitride: 1.5 to 15.0%, one or more selected from the group consisting of W and Mo: 3.0 to 30.0%, and one or more selected from the group consisting of ferrochromium, ferrotungsten, ferromolybdenum, and stainless steel: 2.0 to 20.0%, with the balance being impurities.

摘要： There is provided a brake lining for railway vehicle that can reduce brake squeal in braking. A brake lining (10) for railway vehicle is used for a disc brake system of a railway vehicle. This brake lining (10) includes a base plate (40), a sintered friction material (20), and a friction material supporting mechanism (30). The friction material supporting mechanism (30) is disposed between the base plate (40) and the sintered friction material (20) and supports the sintered friction material (20) in such a manner that the sintered friction material (20) can move with respect to the base plate. The sintered friction material (20) has a Young's modulus of 35.0 GPa or more.
