Is uses the high quality red copper to pass through the special craft for raw material to process the orange specially the indefinite form textile fiber, cuts to pieces after length is 3-5mm. The red copper textile fiber has received the metal simple substance copper low degree of hardness, the wearability, the thermal conductivity good and so on all merits. At present mainly uses in the performance requirement high friction material, it has the stable friction disk friction coefficient in the friction material and reduces the abrasion the function, because also applies the brake friction heat high temperature which has to soften the red copper textile fiber, can replace a part the fever has already lost the bond, the permeating friction disk surface, may enhance applies the brake the effect and prevents the metal hot spot.
