Basalt fiber is an advanced inorganic fiber produced by melting crushed basalt rock—a volcanic rock abundant worldwide—at approximately 1,500°C and extruding it through platinum-rhodium alloy bushings to form continuous filaments. The resulting material is a high-performance, sustainable alternative to traditional glass (fiberglass) and carbon fibers. It exhibits a unique combination of properties: excellent tensile strength, superior thermal resistance (operating from -260°C to over 700°C), good chemical and corrosion resistance (especially in alkaline environments where glass fiber degrades), effective sound absorption, and inherent electrical insulation. As a natural material, its production is relatively energy-efficient and generates no toxic byproducts, positioning it as a "green" material in the composites industry.

The applications for basalt fiber are expanding as its cost-competitiveness improves. Its primary use is as a reinforcement material in polymer composites (basalt fiber reinforced polymer - BFRP), competing with E-glass in automotive parts, pipes, and sporting goods. In construction, it is used in concrete reinforcement meshes and rebar, particularly for structures exposed to corrosive environments like marine settings or road de-icing salts. Its thermal stability makes it ideal for high-temperature insulation fabrics, fireproof textiles, and friction materials (brake pads). Furthermore, it is employed in geotextiles for soil stabilization and erosion control. While its stiffness and strength are lower than carbon fiber, its wider operational temperature range, better chemical stability, and lower cost than carbon make it a compelling choice for a growing range of industrial, automotive, and infrastructure applications seeking durable, fire-resistant, and sustainable composite solutions.
