とができるので好ましい。Then, in order to place the clutch facing member on the backup material and perform thermocompression molding integrally, the molding temperature of 80 ° C or
Make sure that the tensile stress remains on the joint surface of the backup material under the conditions of 300 ° C and surface pressure of 50 kg / cm 2 to 600 kg / cm 2 .
It is advisable to integrally perform thermocompression molding using a mold as shown in FIG. When a clutch facing member having a coefficient of thermal expansion smaller than that of the backup material is used, the molding temperature of the clutch facing member is 80 ° C to 300 ° C,
Molded into the same ring shape as the clutch driven plate at a surface pressure of 50 kg / cm 2 to 600 kg / cm 2 , and then placed on a backup material coated with adhesive, molding temperature 80 ° C to 300 ° C, surface pressure 1
By using the means for integrally thermocompressing at 0 kg / cm 2 to 200 kg / cm 2 , the difference in thermal expansion coefficient between the backup material and the clutch facing member can be used while using the mold normally used for resin mold clutch facing. This is preferable because tensile stress can be left on the joint surface of the backup material.

も時間が節約できるので最も好ましい。Further, when a clutch facing member having a sum of curing shrinkage and thermal expansion coefficient smaller than the thermal expansion coefficient of the backup material is used, the clutch facing member having the above composition is formed into a powder form or at room temperature into the same ring shape as the clutch driven plate. Place on the backup material stored in the mold and clamp the mold, molding temperature 80 ℃ to 300 ℃, surface pressure 50k
By using the means for integrally thermoforming at g / cm 2 or 600 kg / cm 2 , the difference between the coefficient of thermal expansion of the backup material and the sum of the coefficient of thermal expansion of the clutch facing member and the curing shrinkage factor causes This is most preferable because the tensile stress remains in and the time can be saved.

と、全体が均一に塑性変形し最も好ましい。Next, the method of applying a bending moment to the backup material to cause plastic deformation is as shown in FIG. 5, in the same manner as the three-point bending, with the backup material facing down and the clutch driven plate placed on the lower fulcrums 8a and 8b. It is also possible to use a method in which the clutch driven plate is rotated while intermittently applying a force to the upper fulcrum 9 and is continued until the clutch driven plate becomes flat.
As shown in the figure, place the clutch driven plate on the two lower rolls 6a and 6b so that the backup material is on the lower side, press the clutch driven plate with the upper roll 7 from above, and rotate the rolls. When a bending moment is applied to the clutch driven plate, the whole is uniformly plastically deformed, which is most preferable.

た問題を生ずることがない。Further, in the present invention, when a fiber base material, a binder, a clutch facing member such as a friction modifier is placed on a backup material of a light alloy and thermocompression-molded integrally, the tensile stress remains on the joint surface of the backup material. As shown in Fig. 3, since the backup material is placed in a convex state with the backup material facing downward, when the backup material is plastically deformed by applying a bending moment to flatten the clutch driven plate, compressive stress is applied to the clutch facing member. The problem that the clutch facing member is pulled and cracked during plastic deformation of the backup material does not occur.
