    • An improved friction material (20, 50a, 50b) includes inorganic fibers 94 formed from a melt of volcanic black rock (74) and additives (76). The black rock (74) comprises silica oxide, magnesium oxide, potassium permanganate, aluminum oxide, iron oxide, silicon dioxide, titanium dioxide, sodium oxide, and boron. The additives (76) include potassium permanganate and boron. As a result of their composition, the fibers (94) are temperature resistant and lightweight, yet strong. The fibers (94) exhibit a melting point between 1500 degrees centigrade and 1650 degrees centigrade, a working range of -130 degrees centigrade to 700 degrees centigrade, a density of 1.8 g/cc, a surface density between 160 g/m2 and 350 g/m2, and a tensile strength between 500 lbf/in2 and 1800 lbf/in2. The friction material (20, 50a, 50b) is made from layers of the inorganic fibers (94) and a bonding material and has a working temperature between 250 degrees centigrade and 650 degrees centigrade, with a melting point of approximately 1200 degrees centigrade.
    • 改进的摩擦材料(20,50a,50b)包括由火山黑岩(74)的熔体和添加剂(76)形成的无机纤维94。 黑色岩石(74)包括氧化硅,氧化镁,高锰酸钾,氧化铝,氧化铁,二氧化硅,二氧化钛,氧化钠和硼。 添加剂(76)包括高锰酸钾和硼。 由于它们的组成,纤维(94)耐温和轻,而且坚固。 纤维(94)的熔点在1500摄氏度至1650摄氏度之间,工作范围为-130摄氏度至700摄氏度,密度为1.8克/立方厘米,表面密度为160克/平方米至350克 / m2,抗拉强度在500lbf / in2和1800lbf / in2之间。 摩擦材料(20,50a,50b)由无机纤维(94)和粘结材料层制成,工作温度在250摄氏度至650摄氏度之间,熔点约为1200摄氏度。
