Amid the growing demand for lightweight, high-temperature-resistant materials in the aerospace sector, China's basalt fiber industry has achieved a significant breakthrough with the mass production of micron-scale ultrafine fibers at a thousand-ton level. This offers a highly promising solution for the aerospace field. The following analysis covers four dimensions: technological breakthroughs, aerospace applications, industrial ecosystem, and future trends.

The basalt fiber industry is currently in a phase of rapid development. China has overcome key technologies, such as intelligent 2,400-hole bushing drawing and melt homogenization control, which have significantly improved product performance. Basalt fiber is now viable as a replacement for glass fiber in most applications.

Basalt fiber, a material known for its lightweight, high-strength, and corrosion-resistant properties, has a wide range of applications across multiple sectors. This versatile material is particularly valuable in the energy sector and the defense and aerospace industries, where its unique characteristics address complex engineering challenges.

Concrete corrosion is one of the main causes of concrete durability deterioration, and concrete corrosion issues cause huge economic losses every year. To reduce the economic losses caused by concrete corrosion, it is of great significance to study the corrosion resistance of basalt fiber concrete.

With their comprehensive performance advantages, basalt fibers are widely used in a variety of industries, including aerospace, defense, transportation, new energy, construction, marine engineering, and petrochemicals. They serve as an upgraded alternative to traditional materials.

Basalt fiber is a continuous filament fiber made from natural basalt rock. The rock is melted at 1450°C-1500°C and then drawn through a platinum-rhodium alloy bushing at high speed. Pure basalt fiber is typically brown. It's a new type of inorganic, eco-friendly, high-performance fiber composed of oxides like silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide, and titanium dioxide. Basalt continuous fiber not only has high strength but also boasts excellent properties such as electrical insulation, corrosion resistance, and high-temperature resistance. Furthermore, its production process generates minimal waste and environmental pollution, and the discarded product can degrade naturally without harm, making it a truly green and eco-friendly material. China has listed basalt fiber as one of the four key fibers for development (along with carbon fiber, aramid, and ultra-high molecular weight polyethylene) and has achieved industrial production. Continuous basalt fiber is now widely used in fiber-reinforced composites, friction materials, shipbuilding, the automotive industry, and high-temperature and protective applications.

In new residential building structures, basalt fiber-reinforced polymer (BFRP) composites are emerging as a highly promising construction material due to their excellent properties, including high strength, lightweight nature, corrosion resistance, and superior seismic performance. 

Although the initial cost of basalt fiber-reinforced polymer (BFRP) composites is higher, their long-term economic benefits in residential construction are significant.

Chopped basalt fiber concrete should ideally be constructed under temperatures ranging from -5°C to 25°C. Both excessively high or low temperatures can lead to an uneven mix.

Chopped basalt fiber-reinforced concrete involves incorporating a certain amount of continuous or discontinuous chopped basalt fibers into concrete using an appropriate method. This approach preserves concrete's inherent compressive strength advantages while significantly enhancing its toughness and tensile strength, thereby effectively reinforcing and strengthening concrete and extending the service life of engineering structures.
