黑色增強纖維是采用天然磁性鐵礦石、玄武巖、白云巖和石油焦碳等為主要原料經過1400℃的高溫熔爐成熔體，經離心機高速離心成纖維狀，并進行去雜除渣及表面處理等工藝精制成的纖維。
黑色增強纖維具有耐高溫、易分散的優點，同時更有利于使摩擦材料表面更細膩美觀。
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.
