と定めたものである。In the wet friction material of the present invention, the binder phase is 5
If the amount is less than 10% by weight, the role of the binder phase becomes weak and the strength is significantly reduced. On the contrary, if the amount of the binder phase exceeds 40% by weight, the elasticity becomes poor and the plasticity of the binder phase during friction. The fluidity increases, and the friction coefficient is significantly reduced. If the amount of bisallylnadiimide present in the binder phase is less than 50% by weight, abnormal wear is likely to occur at high load or high sliding speed.
Therefore, 5 to 40% by weight of the total wet friction material is defined as the binder phase, and 50% by weight of the binder phase is defined as bisallylnadimide.
