Basalt Fiber Roving
Basalt fiber is a continuous fiber drawn from natural basalt. It is a continuous fiber drawn at high speed through a platinum-rhodium alloy wire drawing plate after the basalt material is melted at 1450℃~1500℃. The color of pure natural basalt fiber is generally brown. Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material. It is composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide and titanium dioxide. Basalt continuous fiber not only has high strength, but also has many excellent properties such as electrical insulation, corrosion resistance and high temperature resistance. Basalt fiber is made by melting basalt ore at high temperature and drawing it. It has silicates similar to natural ore. It can be biodegraded in the environment after being discarded and is harmless to the environment.
China has listed basalt fiber as one of the four major fibers (carbon fiber, aramid, ultra-high molecular weight polyethylene, basalt fiber) for key development and has achieved industrial production. Basalt continuous fibers have been widely used in fiber reinforced composites, friction materials, shipbuilding materials, thermal insulation materials, automotive industry, high temperature filter fabrics and protection fields.
