ることＫある。The present invention was developed in view of the above-mentioned circumstances, and its purpose is to exhibit a stable and high coefficient of dynamic friction, low friction under operating p, v, and lubrication conditions, and low static friction during engagement. It is an object of the present invention to provide a friction material that has a small difference between a coefficient of coefficient and a coefficient of dynamic friction, has high heat resistance, and has a round shape suitable for a clutch facing material.
以下、本発明を図面を参照して説明する。Hereinafter, the present invention will be explained with reference to the drawings.
本発明に係る摩擦材料の実施例として次の組成を設定し
た。The following composition was set as an example of the friction material according to the present invention.
フェノール樹脂： ３０〜４０重量係綿チップ（
帆布のチップ）： ３５〜４０重量係炭素短繊維 ：
１５重重量
％ラファイト： ５重量係
ＰＴＦＥ ’ ５重量％上記組成の摩擦
材料Ａの摩擦係数と面圧の関係および炭素短−維：５重
量係の犀擦材料Ｂの摩擦係数と面圧との関係を図面に示
す。Phenolic resin: 30-40 weight cotton chips (
Canvas chips): 35-40 weight coefficient short carbon fibers:
15% by weight Raffite: 5% by weight PTFE' 5% by weight The relationship between the friction coefficient and surface pressure of friction material A with the above composition, and the relationship between the friction coefficient and surface pressure of friction material B with carbon short fiber: 5% by weight The relationship is shown in the drawing.
綿チップは７エーシングの強厩を確保するためと、弾性
率を低下させ、相手板とのａｂを良好にする効果がある
。量としては２０〜５０重量係が適当であシ、２０重重
量％下では強度が低下するし、５０重重量板上ではフェ
ノール樹脂の量が相対的に低くなシ過き、芯板との接合
性が低下する。The cotton chips have the effect of ensuring the strength of the 7 acing, and of lowering the elastic modulus and improving the AB with the mating board. The appropriate amount is 20 to 50% by weight; below 20% by weight, the strength decreases, and on a 50% weight plate, the amount of phenolic resin is relatively low, resulting in smearing and bonding with the core plate. Bondability decreases.
炭素繊維量は１０重重量風上〜３０重量係が適当である
。５重量係程度では図面８曲線に示すように、実際に必
要な面圧２０〜４０ＫＬｉ／７域での摩擦係数が低い。The appropriate amount of carbon fiber is 10 to 30 weight upwind. When the weight factor is about 5, the friction coefficient is low in the actually required surface pressure range of 20 to 40 KLi/7, as shown in the curve 8 in FIG.
３０重重量板上ではコスト的に難が出てくる。On a 30-weight board, it becomes difficult in terms of cost.
グラファイトおよびＦＴＦＢは共に静摩擦係数と動摩擦
係数の差を小さくする役割をする。Graphite and FTFB both serve to reduce the difference between the static friction coefficient and the dynamic friction coefficient.
特にＦＴＦＢ ＃′ｉ潤滑下低面圧域において図面Ｃ曲
線に示すような高い摩擦係数を示す。グラファイトもＰ
ＴＦＥと同様な傾向にはあるが、この特性はＰＴＦＥＯ
方がより強い。しかしＦＴＦＢを１０重重量％上入れる
ことは、成型上無理てあり、５重量％が上限である。ま
た１重量％以下では効果がない。Particularly in the low surface pressure region under FTFB #'i lubrication, it exhibits a high coefficient of friction as shown in curve C in the drawing. Graphite is also P
This property is similar to that of TFE, but PTFEO
is stronger. However, it is impossible to add more than 10% by weight of FTFB in terms of molding, and the upper limit is 5% by weight. Further, if it is less than 1% by weight, it is not effective.
グラファイトは上述した機能を有すると共にフェノール
樹脂の熱伝導性を高めるのに寄与する。Graphite has the above-mentioned functions and also contributes to increasing the thermal conductivity of the phenolic resin.
ただし、１０重重量％上になると、強度低下芯板との接
合性不良をひき起すし、５重量％以下では有効に機能し
ない。However, if it exceeds 10% by weight, the strength will decrease and poor bonding with the core plate will occur, and if it is below 5% by weight, it will not function effectively.
テスト結果では図面に示したよう゛に、実際のクラッチ
フェーシングが用いられる面圧１０〜５０に４／Ｃａｌ
において、従来のルー擦材料（例えばＣｕ系焼結合金の
動賑擦係数は００６〜α１０）Ｋくらべ高い動摩擦係数
を有しているのがわかる。As shown in the drawing, the test results show that the actual clutch facing has a surface pressure of 10 to 50 and 4/Cal.
It can be seen that K has a higher dynamic friction coefficient than conventional lubrication materials (for example, Cu-based sintered alloy has a dynamic friction coefficient of 006 to α10).
またＰＴＦＢの効果によシ静摩擦係数と動摩擦係数の差
も小さく、炭素繊維、グラファイトの効果により熱伝導
性（基地フェノール樹脂の１０倍）が嵐好なことによシ
耐熱性も高い。Furthermore, due to the effect of PTFB, the difference between the coefficient of static friction and the coefficient of dynamic friction is small, and due to the effects of carbon fiber and graphite, the thermal conductivity (10 times that of the base phenol resin) is excellent, and the heat resistance is high.
また、炭素繊維自身の硬度が高い（ＨＶ７００〜８００
）ととＫよシフエーシングの耐摩耗性も高い。In addition, the hardness of carbon fiber itself is high (HV700-800
) The wear resistance of the Toto Kyo shift facing is also high.
本発明は以上詳述したように、綿チップ：２０〜５０重

る＊ｐｘ材料である。As detailed above, the present invention includes cotton chips: 20 to 50% by weight, carbon fibers: 10 to 30% by weight, polytetrafluoroethylene (PTFE): 1 to 10% by weight, and graphite: 1 to 10% by weight. Part: *px material made of phenolic resin.
