The Future of Basalt Fiber

Basalt fiber in the field of national defense and military applications
Basalt fiber is the fourth largest high-tech fiber after carbon fiber, aramid, ultra-high relative molecular mass polyethylene fiber. It is the 21st century in the field of national defense and military industry has a very important application of a high-tech fibers, is the embodiment of national defense science and technology strategy layout of a new material. Basalt fiber for the reinforcement can be made into a variety of excellent performance of composite materials, in aerospace, rockets, missiles, fighters, nuclear submarines, warships, tanks and other weaponry in the field of national defense and military industry has a wide range of applications.
Basalt fiber in the field of civil engineering and construction applications
Basalt fiber high tensile strength, while acid and alkali resistance, and concrete have basically the same composition, density is also close, so the compatibility and dispersion of basalt fiber is better than other reinforcing fibers, can be used to replace the reinforcing steel for concrete building structure reinforcing materials, not only to improve the strength of the building, but also greatly extend the service life of the building. It can fundamentally and substantially improve the quality of the building, enhance the seismic reinforcement, impact resistance, fire safety, sound absorption, sound damping and warmth and energy saving effect.
Basalt fiber in the fire bulletproof application
Basalt fiber for fireproof clothing is in its infancy, due to its own special properties, used in the field of fireproof clothing has greater advantages. Basalt fiber is an inorganic fiber with the advantages of non-combustibility, temperature resistance (-269 ~ 700 ℃), no toxic gas emissions, good insulation, no melting or dripping, high strength, no heat shrinkage phenomenon.
Application of basalt fiber in transportation
Basalt fiber is a natural and green new material that will play an upgrading role for the infrastructure in the field of transportation. First of all, basalt fiber can improve the quality of transportation infrastructure construction, reduce costs and promote the upgrading of the transportation industry. There are also a large number of projects for harbor and airport construction. Basalt fiber with advanced material manufacturing technology, especially green preparation technology increases the new basic raw materials, and achieves the purpose of energy saving, consumption reduction and environmental friendliness. In addition, basalt fibers are also used in automobile shelves, interior handrails, luggage racks of public vehicles, conveyor racks for automobile manufacturing, refrigerated truck structures, heat-insulating wall panels, seats and so on.
Basalt fibers in petrochemical applications
Basalt fiber composites can trigger a revolution in the oil and gas pipeline industry. Composite pipes made of basalt fiber entangled epoxy resin can be used to transport oil, natural gas, hot and cold water, chemically corrosive liquids, bulk materials, cable ducts, low and high pressure cylinders and oil pipes. Oil pipeline, for example, basalt fiber pipeline construction put into operation, the continuous use of the period of 80 years. At the same time, basalt fiber has excellent high temperature resistance, can be used as a press cushion, refrigerated or gas liquid tank insulation materials, high-temperature purification and filtration materials.
Basalt fiber in the electronics industry applications
Basalt fiber polymer matrix composites are excellent thermal insulation and insulating materials. Basalt fiber volume resistivity is one order of magnitude higher than E glass fiber, the use of basalt fiber dielectric properties and low moisture absorption, temperature characteristics, can be made into high-quality multi-layer printed circuit boards of copper-clad plate. It can also be used as insulating wire skins, transformer molds and reinforcing components. In addition, basalt fibers can be used as reinforcing materials for wind turbine blades.
Basalt fiber in the field of sports and leisure applications
Basalt fiber is one of the earliest applications in this field of fiber, is because basalt fiber has excellent tensile strength. Products that have been developed abroad include: fishing rods, hockey sticks, antennas, skis, umbrella handles, spreader bars, bows and arrows and incompetent bows, sports field benches and so on.
Basalt fiber in the field of medical applications
The lower the acidity coefficient of the fiber, the better its chemical durability and the higher the temperature of use. the higher the pH value, the more alkaline oxides, the worse the water resistance. The acidity coefficient of basalt fiber is 5.48, and the pH value is 1.7. Therefore, basalt fiber has special temperature resistance and good chemical stability, and is used as high-temperature filtration material, which is beneficial to air purification and disinfection in the process of antibiotic production.

Basalt fiber and its composite material is the green material of the 21st century, and it is a competitive new material industry with sustainable development in the world's high-tech fiber industry.
