縁部に固定されて使用される。[Prior Art] In automobiles and the like, a clutch disc that connects and disconnects power between an engine and a transmission has an annular clutch facing attached to the surface of a disc spring. This clutch facing is formed by impregnating glass fiber or organic fiber with a binder component such as phenolic resin and solidifying it, and is used by being fixed to the peripheral edges of both sides of the disc spring with rivets or the like.

に伴なうバースト強度の向上を図るために、組成、形状
、製造方法などについて種々の研究が行なわれている。By the way, one of the performances required of clutch facings is burst strength. This burst strength measures the strength against centrifugal force during high-speed rotation, and corresponds to the strength during actual use. In order to improve the burst strength associated with the recent increase in the output of engines, various studies are being conducted on the composition, shape, manufacturing method, etc.
そのうちの一つに、クラッチフェーシングの主要部であ

たクラッチフェーシングが知られている。One of the known clutch facings is a clutch facing in which a metal reinforcing plate is adhesively fixed to the back side of a friction base material, which is the main part of the clutch facing, that is, the surface facing the disk spring.

ならず、取付は工数が多大となっていた。[Problems to be Solved by the Invention] By the way, when a friction base material and a reinforcing plate are adhesively fixed, it is usually done by interposing an adhesive in the form of a sandwich, sandwiching them between jigs, and thermocompression bonding. However, since the reinforcing plate and the friction base material have significantly different coefficients of thermal expansion due to their different materials, warping in a truncated cone shape may occur after crimping. When such warpage occurs, it is sometimes necessary to deform the clutch facing so that the friction surface is flat when attaching it to the disc spring, which requires a large amount of man-hours.

ることも明らかとなった。Therefore, the present inventors have found that by thermocompression bonding in a state that is forcibly warped in the opposite direction to the direction of warpage after thermocompression bonding, the displacement is canceled and the friction surface becomes flat after thermocompression bonding. discovered. However, it has also become clear that there is a problem in that the burst strength decreases, probably because peeling occurs at the bonded surface when deforming from the warped state during thermocompression bonding to the flat state after thermocompression bonding.
本発明はこのような事情に鑑みてなされたものであり、
熱圧着後の反りの方向とは逆方向に強制的に反らせた状

とを目的とする。The present invention was made in view of these circumstances, and
It is an object of the present invention to improve adhesive strength even when thermocompression bonding is performed in a state where the material is forcibly warped in the opposite direction to the direction of warpage after thermocompression bonding.

It consists of a thin, annular metal reinforcing plate that is integrally adhesively fixed, and the friction base material and the reinforcing plate are integrally adhesively fixed using a rubber-modified phenolic adhesive, so that the friction surfaces are approximately on the same plane.

The binder component binds and holds these fiber components and powder components, and thermosetting resins such as melamine resin and phenol resin are generally used. Further, in order to improve friction performance, rubber may be impregnated as part of the binding material.

Various metals or alloys can be used, but since it is desirable to be lightweight, aluminum alloy is used. is particularly recommended. It is desirable that the thickness of the reinforcing plate be as thin as possible while maintaining strength.

With other adhesives, adhesive strength after thermocompression bonding cannot be obtained, resulting in low burst strength.
［作用］
本発明の環状摩擦材を製造するには、まずそれぞれ別に
形成された摩擦基材と補強プレートとをゴム変性フェノ
ール系接着剤を介して積層する。[Function] In order to manufacture the annular friction material of the present invention, first, a friction base material and a reinforcing plate, which were formed separately, are laminated with a rubber-modified phenolic adhesive interposed therebetween.
次いで一対の圧着治具の間に全体を挟持して加熱圧着す
る。ここで圧着治具の表面は、摩擦基材と補強プレート
とを平らな状態で熱圧着した場合において圧着後に反る
方向とは逆方向に反った形状とされている。すなわち摩
擦基材と補強プレートとを反らせた状態で熱圧着する。Next, the entire body is held between a pair of crimping jigs and heat crimped. Here, the surface of the crimping jig has a shape that is warped in the opposite direction to the direction in which the friction base material and the reinforcing plate are warped after crimping when they are thermocompression bonded in a flat state. That is, the friction base material and the reinforcing plate are bonded by thermocompression in a warped state.
加熱温度および加熱時間は接着剤の接着条件に準じて行

却による収縮により環状摩擦材は既に反っている形状か
ら逆方向へ反り、変位が吸収されて摩擦面が略同一平面
上にある平らな形状となる。The heating temperature and heating time should be determined according to the adhesive bonding conditions. When the annular friction material is removed from the crimping jig, the annular friction material will shrink in the opposite direction from its already warped shape due to cooling, and the displacement will be absorbed, resulting in a flat shape with the friction surfaces on approximately the same plane. .
また接着剤にはゴム変性フェノール系接着剤を用いてい
るので、接着強度を維持しつつ変位に柔軟に追従し、か
つこの接着剤は摩擦基材の結合材成分と親和性に富むの
で、接着強度が高く維持できるものと推察される。In addition, since a rubber-modified phenolic adhesive is used for the adhesive, it can flexibly follow displacement while maintaining adhesive strength, and since this adhesive has high affinity with the binding material component of the friction base material, It is presumed that the strength can be maintained at a high level.
［発明の効果］

件下で使用することができる。[Effects of the Invention] Therefore, according to the annular friction material of the present invention, since the annular friction material has a flat shape after thermocompression bonding, it is easy to attach it to the attachment target part. Furthermore, since the adhesive firmly bonds the friction base material and the reinforcing plate, it has high burst strength and can be used under high-speed rotation conditions.

。Table 1 (blank below) In other words, since the clutch facing of this embodiment has a flat shape, it can be easily attached to the clutch spring with less man-hours. It also has a reinforcing plate and is laminated in one piece for high adhesive strength.
It can be installed in cars with high-speed engines.

表に示す。(Comparative example) A polyimide adhesive (rTA905 manufactured by Mitsui Petrochemicals Co., Ltd.) and a vinyl-modified phenolic adhesive (Cemedine #720J manufactured by Cemedine Co., Ltd.) were used as adhesives, and the drying conditions shown in Table 1 were used. Clutch facings of each comparative example were formed in the same manner as in the example except that they were integrated under crimping conditions. Then, the bending test and burst strength measurement were performed in the same way, and the results were used as the first
Shown in the table.
