由玄武岩等矿物经过粉碎，高温熔化，喷丝，涂胶和短切等加工而成的短纤维可用于无石棉摩擦材料，特别适用盘式刹车片，它具有以下的使用特点： 价格便宜，能较大减低无石棉摩擦材料的成本。 与玻璃纤维和硅石灰相比，能降低摩擦材料的噪音和振动。由于表面涂胶，提高了摩擦材料的耐磨性。 由于岩石棉有比较低的熔化温度，因此，在高温时比较软，因此可以减少对偶的磨损和起到高温辅助黏合剂的作用，因而提高了材料的高温耐摩擦性。是无石棉摩擦材料的重要代用纤维。

The short fibers processed from basalt and other minerals through crushing, high-temperature melting, spinning, gluing and chopping can be used for non-asbestos friction materials, especially for disc brake pads, which have the following characteristics.

It is cheap and can reduce the cost of non-asbestos friction materials.

Compared with glass fiber and silica lime, it can reduce the noise and vibration of the friction material. It can improve abrasion resistance of the friction material due to the surface coating of adhesive.

Since rock wool has a relatively low melting temperature, it is softer at high temperatures, thus reducing the wear on the couples and acting as a high-temperature auxiliary adhesive and improving the high-temperature friction resistance of the material. It is an important substitute fiber for non-asbestos friction materials.
