All or part of in the feature having just mentioned can allow further to improve friction lining and disk support member it
Between connection confrontation radially and/or tangential shear stress intensity.
The surface with residual friction lining for the disk support member that the cohesion region of fracture corresponds to after divesting.
The stickiness region of fracture corresponds to without residual friction material and shows the surface of stickiness fracture.The application's
In meaning, when the thickness of the retained material with continuous fibers is less than 80 μm, then it is considered as region and does not have retained material.
The invention further relates to a kind of frictional disk, and it includes disk support member and one be bonded in the face of the disk support member
On friction lining, wherein, after friction material is peelled off, stickiness break surface be less than the disk support member above is bonded with
The 4% of the surface area in that face of friction lining.
Advantageously, it was found by the inventors that such frictional disk is under about 200 DEG C of conventional heat condition, even can
To be up under 360 DEG C of heat condition with high to centrifugal force resistant intensity.
The invention further relates to the clutch of a kind of clutch, especially motor vehicles, and it includes the friction according to the present invention
Disk.
The invention additionally relates to a kind of by bonding the method being fixed on friction lining on the surface of disk support member, its
In：
- by the solvent-free powder binder deposition based on resin to the surface of disk support member,
