Abstract
A friction couple including a frictionally rubbing member that contains at least one of a binder and a filler, in which the binder and the filler have a modulus of elasticity of 1 GPa or higher and 15 GPa or lower, no softening point or no glass transition point in the range of −50° C. or higher and 200° C. or lower, and a compressive strength of 50 MPa or higher at 25° C. and 25 MPa or higher at 200° C.; and a frictionally rubbed member. The ratio of the maximum value tan δ(Max) to the minimum value tan δ(Min) of the loss tangent tan δ of the frictionally rubbing member obtained through a dynamic viscoelastic measurement performed at a frequency of 0.1 Hz or higher and 20 Hz or lower and in the range of −50° C. or higher and 250° C. or lower after thermoforming is 5 or less.
