Basalt Continuous Fiber

BASALT CONTINUOUS FIBER BASIC CHARACTERISTICS and ADVANTAGES.
MAIN CONSUMERS and RANGES OF USE BCF-BASED MATERIALS

Today significant and steady growth of manufacture of composite materials is observed in the world. One of the basic reinforcing elements of composite materials is fibers. Besides, fibrous materials are widely applied in quality of thermal, sound-proof, and filtering materials.

Now for this purpose glass fibers are widely applied, and for particularly responsible and expensive products carbon fibers are used. However these materials not completely meet the requirements of the present stage. Glass fiber has the certain restrictions under the characteristics: specific durability, temperature of application, chemical stability, especially in alkaline environments. By producing of glass fiber especially scarce component are used – oxide boron (B2O3). Carbon fibers at their high cost have no prospects of mass application.

Therefore to present time it is executed a several works on development of modern "know-how" of continuous fibers from basalt breeds, the industrial producing of basalt continuous fibers and materials on their basis are started. By industrial production of basalt fibers use of new technologies their cost price is close to the cost of glass fiber, and more times cheaper then cost price of carbon fiber. Carbon fiber is more durable material as compared to glass fiber, but other properties of carbon fiber are close to the properties of basalt fiber. Basalt fiber is perspective for substituting costly carbon fiber and producing combined carbon-basalt composite materials.

Thus basalt fibers and materials on their basis have the most preferable parameter a ratio of quality and the price in comparison with glass and carbon fibers, and other types of fibers.

BASIC CHARACTERISTICS & ADVANTAGES CBF

High durability

Strength-to-weight ratio of a basalt fiber exceeds strength of alloyed steel 2.5 times, strength of fiber glass – 1.5 times.

High chemical durability to impacts of water, salts, alkalis and acids

Unlike metal, BCF is not affected by corrosion. Unlike fiber glass, BCF is not affected by alkali. BCF possess high corrosion and chemical durability qualities towards corrosive mediums, such as salts and acids solutions and, especially, alkalis. 

High thermal resistance

A range of temperatures for long-time application of BCF is 200~600 0C.
 Short-term impact of temperatures – up to 700 0C; single impact of temperatures – up to 1000 0C.

Compatibility of BCF with other materials

High compatibility of BCF with other materials (metals, plastic, glues) during producing process.
Materials made on BCF basis can be processed with application of different “cold” technologies, such as moulding, winding, pultrusion, sputtering, etc.

See article. Prospects of application of materials made from basalt fibers

The main BCF products are basalt fiber roving in bundles 10 ~ 20 kg in weight and basalt twisted thread (yarn). Basalt fiber roving shall be used for producing chopped basalt fiber, basalt plates for composites, basalt paper, basalt needled mat, basalt chopped strand mat, basalt roving fabrics, road geo textile nets, shaped basalt-plastic materials, reinforcing materials, rebar, composite coatings, and evaporated materials.
Basalt yarn can be used for producing different types of basalt fabrics and reinforcing nets.

Reinforcing meshes and geo grids

Reinforcing meshes and geo gridsGBF-25W type of Geo textile nets (grids) have wide prospects of application as reinforcing material at the construction of road, highways and take-off runways; for reinforcement at the construction of dams, at the coast protection works.
BFN-5, BFN-10 nets (meshes) use for reinforcement of plastering covering at the building construction.
BFN-4, BFN-5 nets can use as reinforcing material of abrasive disks for cutting metal.
BFN-1 nets can be used as filters for industrial and municipal waste water, as filters for cleaning of waste gases from dust and industrial drains, for filtration of metals melt during casting.

ВМС (N) needled punched fabrics on the basic of basalt continuous fiber have application in the exhaust system muffler of “Toyota” automobiles during many years. BCF needle – punched fabrics (mats) are materials with a high quality for fire-safe doors, fire walls (gables) and fire proof structures, cable tunneling, for protection of the support frames. Under fire and high temperature action BCF needle – punched fabrics no discharge hazardous substances, it is possible to apply it for temperature of standard flame. Basalt Fiber needled mat are made by random entanglement of single chopped fibers to form a three - dimension structure. This structure gives stability to BCF needle – punched products; its can use as thermal insulation for gas-compressor units of the gas-main pipeline station. These BCF materials have a good heat insulating and soundproof characteristics.

COMPOSITES made from BCF roving

BCF roving use for manufacturing of shaped basalt-plastic materials, basalt-plastic rebar and rods, for production of chemically proof products: pipes, cylinders, tanks for aggressive liquids, acids, alkalis, chemical fertilizers, pesticides, poisonous substances.

Basalt-plastic composites: tubes, high pressure vehicles, pipes of big diameter

Basalt-plastic composites made from BCF

Basalt fiber has specific ranges of use due to its properties. As basalt fiber is characterized by chemical and thermal stability, this material can be used in areas where the use of other materials is inefficient. For example, basalt fiber can be used in production of geo textiles, reinforcing materials, high-temperature filters, materials for automobile industry, reinforcing nets, composite materials, for reinforcing concrete building structures and road asphaltic-concrete pavements and for producing waterproof materials. The companies that use glass fiber and carbon fiber for producing composite materials can use basalt fiber for this purpose.
