Against the backdrop of surging demand for lightweight, high-temperature resistant materials in the aerospace field, China's basalt fiber industry has achieved a breakthrough in mass production technology for micron-scale ultra-fine fibers, with performance indicators highly aligned with the needs of aerospace infrastructure. This provides disruptive solutions for deep space exploration, spacecraft protection, and lunar base construction.

In the mysterious and unfathomable world of the deep sea, a materials revolution sparked by "rocks" is unfolding. Basalt fiber—this high-tech fiber derived from volcanic rock—is transforming into the "steel skeleton" of deep-sea oil and gas platforms, the "lightweight armor" of deep-sea robots, and the "stable foundation" of offshore wind power. It not only breaks the constraints imposed by the extreme deep-sea environment on human exploration but also reshapes the competitive landscape of the deep-sea economy with its astonishing performance, including a 15% increase in extraction efficiency and a 30% extension of equipment lifespan. Let's explore the "new deep-blue era" ushered in by basalt fiber.

Basalt, a rock formed from the cooling of volcanic lava, is abundant on Earth. Through high-temperature melting and fine drawing, basalt fibers are produced, using a manufacturing process similar to that of glass fibers. At high temperatures of 1450℃ to 1500℃, basalt rock is melted and then drawn at high speed through a high-temperature resistant alloy spinneret to produce continuous fibers. These fibers have a strength comparable to high-strength glass fibers. Furthermore, basalt fiber, as a new type of inorganic, environmentally friendly, high-performance fiber material, contains various oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide, and titanium dioxide, giving it excellent physical and chemical properties.

Basalt fiber is an inorganic fiber material made primarily from natural basalt rock. It is processed through high-temperature melting and drawing processes, resulting in stable chemical and physical properties. This fiber has applications in various fields, characterized by its abundant raw material source and relatively simple production process.

In a strategic move toward sustainable infrastructure, high-performance basalt fiber needled mats have been specified for major port facility upgrades across Europe. Designed to meet the rigorous demands of coastal and marine engineering, these innovative 750 g/m² and 950 g/m² basalt geotextiles are redefining durability and environmental resilience in heavy-duty geotechnical applications.

Basalt is widely distributed and inexpensive in my country. Its fiber production cost is low, and it has significant comprehensive advantages compared to chemical fibers, carbon fibers, and glass fibers. It has great market potential and is a new type of high-tech, high-value-added product for the new era.

Basalt fiber is not only high in strength, thermally stable, resistant to damage to mating surfaces, and exhibits low wear and a stable coefficient of friction, but it is also reasonably priced. Applying basalt fiber to friction reinforcement materials not only increases the lifespan and operating temperature of automotive friction materials, but also addresses various unfavorable factors in current friction materials, helping to solve the thermal fade phenomenon in traditional automotive brakes, thereby reducing traffic accidents.

Basalt fiber, as a natural green inorganic fiber, is made from natural basalt through melt drawing. It possesses unique advantages such as low carbon footprint, environmental friendliness, lightweight, strong weather resistance, and excellent mechanical properties. After composite modification and process innovation, it has achieved large-scale application in the field of automotive cabin materials, reshaping the cabin material system from multiple dimensions of environmental protection, performance, and cost, injecting core momentum into low-carbon travel.

Natural and non-toxic material basalt fiber is produced by melting and drawing volcanic rocks. To create basalt fibers, basalt ore is heated to about 1500°C before being drawn into continuous threads through platinum-rhodium alloy spinnerets.

Basalt fiber untwisted Cloth is a thin fabric woven from continuous basalt fiber filaments (untwisted or weakly twisted) using simple weave structures such as plain and twill. Its core value lies in maximizing the retention of the mechanical properties and functionality of basalt fibers through a structural design of "low twist + high continuity," making it an ideal reinforcing substrate in the field of composite materials.
