Brief history and advantages of basalt fiber

Frenchman Paul DH é first proposed the idea of extruding fibers from basalt. He obtained an American patent in 1923.
Around 1960, the United States and the Soviet Union began to study the application of basalt fiber, especially in the military field. In 1970, glass companies in the United States implemented a research strategy to make glass fiber more popular than basalt fiber, while in Eastern Europe, research was nationalized by the Soviet Ministry of defense.
After the disintegration of the Soviet Union in 1991, the research results of the Soviet Union were declassified and can be used in the civil field.
Nowadays, the research, production and most marketing of basalt fiber are mainly concentrated in some countries that once belonged to the Soviet Union (Ukraine, Russia) and China.

Fibers are threads that can be made of minerals, metals and synthetic fibers.
The most famous fiber types are as follows: steel fiber, basalt fiber, polypropylene (polymer) fiber, glass fiber, polyester fiber and carbon fiber.
The fiber is mainly designed to improve the strength characteristics of various materials (concrete, asphalt, plastic, rubber, etc.) and is used as reinforcement additive.
All types of fibers have different technical characteristics, so they have their advantages and disadvantages.
Basalt fiber is made of basalt. Basalt is a kind of igneous rock, which was formed by the massive influx of lava into the earth's surface in prehistoric times. The unique properties of this rock are affected by a series of processes in the formation of the crust, namely the melting and solidification of the mantle. Basalt is characterized by high resistance to corrosive environment, the highest corrosion resistance, and will not lose its performance with the passage of time. Basalt fiber inherits all these characteristics and has a lower cost compared with carbon fiber, alkali resistant ar glass and polypropylene.
