黑色增强纤维是采用天然磁性铁矿石、玄武岩、白云岩和石油焦碳等为主要原料经过1400℃的高温熔炉成熔体，经离心机高速离心成纤维状，并进行去杂除渣及表面处理等工艺精制成的纤维。
黑色增强纤维具有耐高温、易分散的优点，同时更有利于使摩擦材料表面更细腻美观。
The Black Reinforced fibre taking natural magnetic iron ore, basalt, dolomite and petroleum coke as main raw materials appears fibrous by the technology of melting by high temperature over 1400℃ and centrifugal wire throwing then remove impurities and shot and surface treatment. 
   The black reinforced fiber has advantages of high temperature resistance and easy dispersion, meanwhile it can make the friction material surface more delicate and beautiful.
