摘要： 本発明は摩擦材料に関わり、さらにとりわけ、従来の製紙プロセスを使って製造できる湿式摩擦材料に関する。 湿り気を付与した一様な骨組マトリクスを形成するために長いファイバーが使われ、そのファイバーは、摩擦マトリクス全体およびマトリクスバインダー全体に、特に隣接したファイバーの隙間において粒子状材料を分散させることによって補強され、それにより材料の剪断強度を著しく増やす一方で、材料を通る流量に対するほとんど無視できる影響を持つ。

摘要： PROBLEM TO BE SOLVED: To provide a wet friction material with an increased coefficient of friction, and a method of manufacturing the material.SOLUTION: The wet friction material includes a pulverized cork heated to 150-200°C, if necessary. The pulverized cork is mixed with paper-making materials of other wet friction material and formed into a paper-made substrate. The paper-made substrate is impregnated with a synthetic resin to be a binder and heated and cured. The cork itself has a high friction coefficient μ. Moreover, powder thereof increases the surface area and an area in contact with a separator plate of a counter member, thereby improving a friction coefficient of a friction surface of the wet friction material. The friction coefficient μ of the cork itself and capacities for absorbing and discharging oil are improved by heating the cork. Thus, there is provided the wet friction material that has a higher friction coefficient μ. An increase in the friction coefficient μ, weight reduction by reducing the number of friction materials, and high efficiency are achieved when used as a wet friction material.

解决方案：如果需要，湿摩擦材料包括加热至150-200℃的粉碎软木塞。 将粉碎的软木与其它湿摩擦材料的造纸材料混合并形成纸制基材。 用合成树脂浸渍造纸基材作为粘合剂并加热固化。 软木本身具有高摩擦系数μ。 此外，其粉末增加表面积和与对置构件的隔板接触的面积，从而提高湿摩擦材料的摩擦面的摩擦系数。 软木本身的摩擦系数μ以及通过加热软木来提高油的吸收和排出能力。 因此，提供了具有较高摩擦系数μ的湿摩擦材料。 当用作湿摩擦材料时，可以实现摩擦系数μ的增加，减少摩擦材料的重量减少和高效率。 版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a wet paper friction material which has both of excellent frictional characteristics and high friction coefficient.
SOLUTION: The wet paper friction material is manufactured by impregnating a paper material with thermosetting resin, and then by hardening the impregnated paper material by heating it, and further by forming it by press working. The paper material contains aramid pulp adjusted so as to have freeness of 200 to 400 ml and aramid pulp adjusted so as to have freeness of 450 to 700 ml respectively by 10 to 50 wt.% of total paper material in addition to cellulose pulp and filler. Further, the surface roughness before and after press-forming by a surface finishing method is adjusted so as to be Rmr(30%)≥55%, where Rmr(C) (C:cutting level %) is a load length factor. As a result, a high friction coefficient, high heat resistance, and high mechanical strength are simultaneously satisfied.
