Basalt fiber is an inorganic fiber material made from natural basalt rock mineral, which is melted at high temperatures and then drawn into fibers. It belongs to the category of high-performance fibers, similar to common glass fiber and carbon fiber, but differs in raw material source, production process, and certain performance aspects. The following analyzes basalt fiber technology across multiple dimensions.

In recent years, China's highway engineering construction has developed rapidly, and concrete structure technology has achieved significant progress, accumulating numerous advanced and mature technical achievements. Concrete structure design has been widely applied in the field of infrastructure construction, demonstrating its importance. However, along with these achievements, the problem of concrete cracking is becoming increasingly prominent. The presence of cracks compromises the performance of concrete, notably reducing its tensile strength, which is the primary reason for the brittle failure exhibited by concrete. Short-cut basalt fiber, as a novel fiber material, has become an excellent concrete reinforcement material due to its unique mechanical properties, good stability, and high cost-effectiveness. This article will focus on the characteristics of short-cut basalt fiber and explore its practical application in concrete reinforcement and strengthening.

High-performance fibers are reshaping the industrial landscape. Basalt fiber, with its natural weather resistance and cost-effectiveness, is driving the green upgrade of infrastructure. Carbon fiber, with its lightweight and high-strength properties, is leading the low-carbon transformation of the aerospace industry. Both are simultaneously penetrating new energy and high-end equipment sectors, forming an upgrade matrix that covers multiple industries.

Under the dual drivers of the "Dual Carbon" goals and the upgrade of high-end manufacturing, high-performance fibers, with their core advantages of "customized performance and application-specific scenarios," have become key materials for solving traditional industrial pain points and advancing emerging fields. Basalt fiber, leveraging its "natural weather resistance and cost-effectiveness," is reshaping the path to green infrastructure. Carbon fiber, with its "lightweight and high-strength" advantages, is leading the low-carbon transition in aviation. The two are also simultaneously entering new energy and high-end equipment sectors, creating a multi-industry upgrade matrix that provides critical support for high-quality manufacturing development.

In the market for high-pressure pipes, composite materials like glass fiber, carbon fiber, and basalt fiber are all used. However, glass fiber reinforced plastic (GRP) high-pressure pipes are the most widely used, while basalt and carbon fiber pipes are less common. Basalt fiber composite high-pressure pipes, with their exceptional corrosion resistance, lightweight and high strength, low fluid resistance, and long service life, are finding widespread applications in various fields such as petrochemicals, aerospace, and construction.

CHINA BEIHAI FIBERGLASS is excited to announce its participation in the 7th International Composites Industry Exhibition (Eurasian Composites Show) at the Istanbul Expo Center, Turkey, from November 26-28, 2025. We warmly invite all attendees to visit our booth and explore the vast potential of our advanced phenolic fiberglass composite materials.

The tensile strength of basalt mineral fibers is a comprehensive indicator influenced by various factors. When selecting and using them, one should not only look at the nominal value but also consider the specific application scenario, cost budget, and other factors. With continuous improvements in production technology, the application prospects for this eco-friendly, high-performance fiber will be even broader.

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.
