Basalt fiber is a type of advanced material made from volcanic rock, specifically basalt, which is melted and spun into fiber. It is known for its excellent strength, high resistance to heat and corrosion, and durability. Basalt fibers are often used as a reinforcing agent in composite materials for various applications, including construction, automotive, aerospace, and infrastructure. Compared to traditional glass fibers, basalt fibers offer better thermal stability and environmental resistance, making them ideal for demanding conditions. Additionally, basalt fiber is considered more eco-friendly due to its natural origin and lack of harmful emissions during production.
