重性にすぐれ、低摩擦係数を有していることは公知であ
る。In general, PTFE bearings have a wide range of uses as so-called oil-less bearings that do not require lubricant.
In particular, it is known that a bearing having a PTFE fiber cloth on the surface of the metal backing has excellent load resistance and a low coefficient of friction.

生じるなどの欠点がある。However, although PTFE fibers are disposed and supported on the surface of another member, that is, a hard backing material such as resin or metal, they have drawbacks such as a weak bond with the backing material, so-called adhesive strength, which may cause peeling.

There is little consideration given to letting people do so.

のである。That is, a resin-treated PTFE interwoven fabric is made of PTFE fibers and other fibers other than the PTFE fibers, and the PTFE fibers occupy 60 to 85φ on the surface, and are impregnated with 25 to 40% by weight of thermosetting synthetic resin. The surface material is made of thermoplastic polyester fiber and cotton fiber, and the blend ratio of the former and the latter is 70:30 to 30 near 0. Resin processing is made by impregnating a thermosetting synthetic resin with 40 to 55 weight φ. A cloth is used as a backing material, and one or more layers of the backing material and the surface material are heated at a temperature of 120 to 200°C and a pressure of 20 to 60 kg.
PTF' characterized by integrally heating and press-forming under conditions of /i time of 0.5 to 2 minutes per wall thickness plate.
The present invention provides an E-woven fabric laminated composite material and a method for manufacturing the same.
本発明において、表層材はＰＴＦＥ繊維と該ＰＴＦＥ繊
維以外の強度が大きく、接着性を損うことのない他の繊
維、たとえば綿繊維もしくはガラス繊維との交織布から
なり、その一方の表面（摺動面）にＰＴＦＥ繊維の占め
る割合が６０〜８５饅の範囲となるように交織されたも
のである。In the present invention, the surface layer material is composed of a woven fabric of PTFE fibers and other fibers other than the PTFE fibers, which have high strength and do not impair adhesiveness, such as cotton fibers or glass fibers, and one surface (sliding The fibers are interwoven so that the proportion of PTFE fibers on the moving surface is in the range of 60 to 85.
表面に占めるＰＴＦＥ繊維の割合が少ないと摩擦係数の
増大を招き、またＰＴＦＥ繊維の割合が多くなると摩耗
量の増加を招くことになり、摩擦摩耗の観点から上記範
囲のものが好ましい。If the proportion of PTFE fibers on the surface is small, the coefficient of friction will increase, and if the proportion of PTFE fibers is large, the amount of wear will increase, so from the viewpoint of friction and wear, the above range is preferable.
そして、表面に６０〜８５饅の割合でＰＴＦＥ繊維が占

とから、交織組織を変化させる方法、例えば朱子織、斜
文織などによって得ることが好ましい。A surface material made of a mixed woven fabric with 60 to 85% PTFE fibers on the surface can also be obtained by changing the thickness of each fiber, but when forming a sliding surface, it is necessary to Since it is desirable that the surface ratio and arrangement distribution of the PTFE fibers and other fibers that appear are uniform, it is preferable to obtain the fibers by a method that changes the interweaving structure, such as satin weave or twill weave.
また、本発明において裏材は、熱可塑性ポリエステル繊
維と綿繊維とから混紡布であって、その混紡比率を熱可
塑性ポリエステル繊維と綿繊維が７０：３０から３０ニ
ア０とした混紡布である。Further, in the present invention, the backing material is a blended fabric made of thermoplastic polyester fibers and cotton fibers, and the blending ratio is from 70:30 to 30 near-0.
裏材として熱可塑性ポリエステル繊維を使用することは
、該ポリエステル繊維自身が可撓性を有すること、また
裏材に後述する熱硬化性合成樹脂を含浸させたきい、該
ポリエステル繊維にはほとんど含浸されないため、裏材
として可撓性が発揮されるものである。The use of thermoplastic polyester fibers as the backing material is because the polyester fibers themselves are flexible, and because the backing material is impregnated with the thermosetting synthetic resin described below, the polyester fibers are hardly impregnated. Therefore, it exhibits flexibility as a backing material.
この点、従来の綿布、アスベスト布、ガラス布、紙、不
織布などからなる裏材とは大きく相違するものである。In this respect, it is greatly different from conventional backing materials made of cotton cloth, asbestos cloth, glass cloth, paper, nonwoven fabric, etc.
そして、熱可塑性ポリエステル繊維の割合が多くなると
強度の低下を招き、綿繊維が多くなると可撓性が低下し
、割れ、剥離を生じるようになる。When the proportion of thermoplastic polyester fibers increases, the strength decreases, and when the proportion of cotton fibers increases, the flexibility decreases, causing cracking and peeling.
前述した表層材および裏材に含浸せしめる合成樹脂は、
フェノール樹脂、エポキシ樹脂、ｍ−クレゾール樹脂な
どの熱硬化性合成樹脂が使用されるが、場合によっては
これらの樹脂に二ｌ−ＩＪルゴム、ネオプレンゴムなど
のゴム質を配合した変性樹脂も使用される。The synthetic resin that is impregnated into the surface material and backing material mentioned above is
Thermosetting synthetic resins such as phenol resins, epoxy resins, and m-cresol resins are used, but in some cases, modified resins that are blended with these resins with rubber properties such as di-IJ rubber and neoprene rubber are also used. Ru.
とくに変性樹脂の使用は成形品により以上の可撓性を付
与し、衝撃強さを向上せしめるほか、表層材と裏材との
剥離強度を増大せしめるのに役立つものである。In particular, the use of modified resins is useful in imparting greater flexibility to the molded product, improving impact strength, and increasing peel strength between the surface material and the backing material.
そして、表層材に含浸せしめる熱硬化性合成樹脂の含浸
量は２５〜４０重量饅が好ましく、４０重重量上り多く
なるとＰＴＦＥ繊維の占める割合が多い表面に現われて
ＰＴＦＥ繊維自体の低摩擦性を殺して摩擦係数を増大せ
しめ、また２５重重量上り少ないと裏材との結合力を弱
めることになる。The amount of thermosetting synthetic resin impregnated into the surface layer material is preferably 25 to 40% by weight.If the amount exceeds 40% by weight, it will appear on the surface where the PTFE fibers occupy a large proportion and destroy the low friction properties of the PTFE fibers themselves. If the weight is less than 25%, the bonding force with the backing material will be weakened.
また、裏材に含浸せしめる熱硬化性合成樹脂の含浸量は
４０〜５５重量φが好ましく、５５重重量上り多くなる
と反って強度が低下し、４０重重量上り少なくなると裏
材同志の結合力が低下し、裏材として使用し難くなる。In addition, the amount of thermosetting synthetic resin impregnated into the backing material is preferably 40 to 55 weight φ; if the weight exceeds 55 weight, it will warp and the strength will decrease, and if the weight decreases by 40 weight, the bonding force between the backing materials will decrease. It becomes difficult to use as a backing material.
なお、表層材と裏材に含浸せしめる熱硬化性合成樹脂は
同一のものを用いることが、該表層材と裏材との接着強
度を向上させる観点から好ましいが、必ずしもこれにこ
だわるものではなく、たとえば表層材には上述した熱硬
化性合成樹脂を、裏材にはゴム変性熱硬化性合成樹脂を
含浸させたものを使用することもできる。Note that it is preferable to use the same thermosetting synthetic resin to impregnate the surface material and the backing material from the viewpoint of improving the adhesive strength between the surface material and the backing material, but this is not necessarily the case. For example, the surface layer material may be impregnated with the above-mentioned thermosetting synthetic resin, and the backing material may be impregnated with a rubber-modified thermosetting synthetic resin.
このように形成された表層材と裏材とは、一層もしくは
二層以上積層された裏材上に該表層材を単層で、かつ表

ように積層し温度１２０゜〜２００℃、成形圧力２０〜
６０ ｋｇ／ｃｙｊ、で一体成形することにより積層複
合材料が形成される。The surface material and backing material formed in this way are a single layer of the surface material on a backing material laminated with one or more layers, and the surface with a high proportion of PTFE fibers is the sliding surface. Laminate them at a temperature of 120° to 200°C and a molding pressure of 20 to
A laminated composite material is formed by integral molding at 60 kg/cyj.
とくに、成形圧力が２０ｋｇ／Ｃｒ？Ｌより低くなると
剥離を生じやすくなり、また６０ｋｇ／ｃＩＩＬより高
くなると表層材のＰＴＦＥ繊維に損傷を生じるようにな
るため十分注意を必要とする。Especially when the molding pressure is 20kg/Cr? If it is lower than L, peeling will easily occur, and if it is higher than 60 kg/cIIL, the PTFE fibers of the surface layer material will be damaged, so care must be taken.
また、成形時間はとくに板状の積層複合材料を製造する
場合、該複合材料の厚さによって決められ、概ね肉厚１
間に対して０．５〜２分間が適当である。In addition, especially when manufacturing a plate-shaped laminated composite material, the molding time is determined depending on the thickness of the composite material, and is generally determined by the thickness of the composite material.
A suitable time is 0.5 to 2 minutes.
