Basalt fiber is similar to carbon fiber and fiberglass, but basalt has better mechanical properties than fiberglass and is lower in cost than carbon fiber. It is used as a fireproof textile in the aerospace and automotive industries and can also be used as a composite to produce a wide range of products

Features High strength and high modulus fiber Excellent shock resistance - good for ballistic applications Low cost alternative and can replace carbon fiber in some applications including filament winding High temperature resistance and good light resistance Good fatigue and corrosion resistance properties No need for special processing equipment Easy to handle and process Environment friendly. Basalt-reinforced composites can meet OEM's disposal requirements because complete disposal by incineration is possible. Huge contamination issues are often caused by incinerating glass fiber composites. Can be recycled Exhibit no health and safety risks Compatible with many resins - unsaturated polyester, vinyl ester, epoxy, phenolic, etc. Better chemical resistance than e-glass

Continuous Basalt Fiber Roving   [Jump to Top]
Continuous Basalt roving is made of a bundle of parallel strands without twisting. Tensile strength of the roving 6-13μ is ≥ 0.6N/Tex Elastic modulus is ≥ 91GPa Elongation at break ≥ 3.1% High temperature and light resistance. It is an inorganic fiber which can be used as a ballistics and protection material. It has an explosive prevention function which when used with ballistic materials is useful when there is an explosive blast. Also there is no bounce, no spalling, no second execution fracture function, which is useful when used as a base material of a ceramic facing armouring system.	Above - basalt roving

Continuous Basalt Fiber Textile Yarn  [Jump to Top]
Continuous basalt textile yarn is made of multiple basalt strands by primary twisting (usually the filament diameter is under 9μm). Continuous basalt textile yarns can be divided into weaving yarns and industrial yarns, and weaving yarns are usually made into cylindrical or milk bottle shape packages.

Basalt Cloth & Unidirectional  [Jump to Top]
Basalt Fiber Cloth Above - basalt plain weave cloth	Basalt Fiber Unidirectional Cloth Above - basalt unidirectional weave cloth
Basalt fiber fabrics are woven from continuous basalt yarn (diameter under 9µ) which can be custom-made to your needs. This fabric can handle temperatures of -260°C to 650°C. Different coatings can improve their properties including better flexibiliy, wearability, wave transparencies, water resistance, radiation resistance, thermo-shock resistance, chemical resistance and excellent temperature resistance (both high and low).	Continuous basalt fiber unidirectional fabric is a high performance engineering material with fibers of the fabric produced by GBF which are coated with sizes comparible with polyester, epoxy, phenolic and nylon resins, which improve the reinforcement effect of the basalt fiber unidirectional fabric. Basalt fiber belongs to the silicate home and has the same thermal expansion coefficient, which makes it the best alternative to carbon fiber applied in the bridge, contruction reinforment and repair. Its BDRP & CFRP has outstanding comprehensive property and cost effectiveness.
Fields of Application - Fabrics Base Cloth for: CCL Needled felt Fireproof fabrics Radiation-proof materials Chemical resistant materials Infrastructure repair and strengthening They are particularly suitable for uses as awnings for anti-toxicity, anticorrosion, radiation - proof fire-proof purposes and for their equipment and facilities to be highly shielded.	Fields of Application - Unidirectional The reinforcement & repair of the construction and bridge. Radar cover, engine parts and radar lines. The body of the armored vehicle, structural parts, wheels and sleevers. Water ski, surfboard and surfing board.

Continuous Basalt Fiber Chopped Strands  [Jump to Top]
Produced by cutting continuous basalt fiber and coated in silane sizing. Chopped strands are the best way to reinforce thermoplastic resin and reinforce concrete. Basalt chopped strands contains a special silicate, which gives it an excellent chemical resistance and an alkali tolerance. Basalt fiber chopped strands are the perfect material to take the place of PP & PAN to reinfoce cement and concrete to improve the stability, low-temperature crack and fatigue resistance.	Above: basalt chopped strands
Fields of Application Reinforcement for thermoplastic resins, SMC, BMC and DMC Reinforcement for automobile, train and ship hulls Reinforcement for cement and concrete, used for dams in hydropower plants, cooling towers in thermal power plants, and steam pipelines in nuclear power plants Heat resistant needled felts, automobile mufflers and heat insulation carpets for steel rolling Basalt fiber chopped strands technical index Product No. Diameter (µm) Length (mm) Sizing type Moisture content (%) CBF13-6 13 6 Silane 0.1 CBF15-12 15 12 Hydrophilicity 6 CBF18-25 18 25 Lipophilicity 6 CBF22-70 22 70 Lipophilicity 6
