Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material, basalt continuous fiber is not only high strength, but also has a variety of excellent properties such as electrical insulation, corrosion resistance, high temperature resistance. Basalt fiber is made by melting basalt ore at high temperature and drawing it into wire, which has silicate similar to natural ore, and can be biodegraded in the environment after waste, which is harmless to the environment. Basalt continuous fibers have been used in a wide range of applications, including fiber-reinforced composites, friction materials, shipbuilding materials, thermal insulation materials, the automotive industry, high-temperature filtration fabrics, and protective fields.
