Abstract:
(EN) Provided is a friction material composition capable of improving friction coefficient or wear resistance, reducing compressive stain, and improving yield during heat molding, even when the composition does not contain a copper component or has a low content of the copper component. The friction material composition contains: titanate compound powder composed of non-fibrous titanate compound particles; barium sulfate powder; and a thermosetting resin, wherein the alkali metal ion dissolution rate of the titanate compound powder is 15.0 mass% or less, the particle diameter at 50% in a volume-based cumulative distribution of the barium sulfate powder is 0.1-20.0 µm, and the content of a copper component is 0.5 mass% or less as elemental copper with respect to 100 mass% total of the friction material composition.
(FR) L'invention concerne une composition de matériau à friction capable d'améliorer le coefficient de frottement ou la résistance à l'usure, de réduire la déformation par contrainte et d'améliorer le rendement pendant le moulage à chaud, même lorsque la composition ne contient pas de composant de cuivre ou a une faible teneur en composant de cuivre. La composition de matériau à friction contient : une poudre de composé de titanate composée de particules de composé de titanate non fibreux ; une poudre de sulfate de baryum ; et une résine thermodurcissable, le taux de dissolution d'ions de métal alcalin de la poudre de composé de titanate étant inférieur ou égal à 15,0 % en masse, le diamètre de particule à 50 % dans une distribution cumulative basée sur le volume de la poudre de sulfate de baryum étant compris entre 0,1 et 20,0 µm, et la teneur en composant de cuivre étant inférieure ou égale à 0,5 % en masse en tant que cuivre élémentaire, rapporté à 100 % en masse totale de la composition de matériau à friction.
(JA) 銅成分を含有しない又は銅成分の含有量を少なくした場合においても、摩擦係数や耐摩耗性を向上させ、圧縮変形率を小さくすることができ、加熱成形時の歩留まりを改善することができる、摩擦材組成物を提供する。 非繊維状のチタン酸塩化合物粒子から構成されるチタン酸塩化合物粉末と、硫酸バリウム粉末と、熱硬化性樹脂とを含有する摩擦材組成物において、前記チタン酸塩化合物粉末のアルカリ金属イオン溶出率が15.0質量%以下であり、前記硫酸バリウム粉末の体積基準累積50%粒子径(D50)が0.1μm~20.0μmであり、前記摩擦材組成物の合計量100質量%において銅成分の含有量が銅元素として0.5質量%以下であることを特徴とする、摩擦材組成物。
