Basalt fibers, quartz glass fibers, chrysotile asbestos, mullite fibers, brucite fibers, and acicular wollastonite all belong to inorganic nonmetallic fibers or whisker materials, with excellent mechanical and mechanical properties. They are widely used as reinforcing materials and structural materials in various composite materials. Here, based on a brief introduction to basalt fibers, the focus is on the special mechanical functional effects such as superhardness, sealing, pressure transmitting, friction, and lubrication generated by the hardness, pore structure, and layered structure of minerals, as well as the corresponding mechanical functional mineral materials.
