CBF Properties

Continuous Basalt Fiber (CBF) is a unique inorganic material derived from natural mineral sources. It inherently possesses exceptional mechanical strength, excellent abrasion and tear resistance, impact toughness, corrosion resistance, and high thermal and chemical stability. Additionally, CBF is lightweight and environmentally friendly, making it an ideal choice for a wide range of advanced applications. 

• Extremely high chemical resistance in acidic and alkaline environments.

• Good adhesion to various materials.

• Does not accumulate static electricity. Very high resistance to electromagnetic emanation.

• 100% dielectric.

• Transparency to radar radiation.

• It does not suffer from corrosion, is rust-free, and is stable in any liquid or gaseous medium.

• Lightweight and high mechanical strength, which allows you effectively to reinforce the product.

• High thermal stability. Extended range of application temperatures (from -260 °C to +800 °C, withstands up to +1000 °C in the short term).

• High resistance to radiation and UV.

• Incombustibility.

• Excellent sound and vibration insulation properties.

• Effective fire and thermal protection.

• Anti-catastrophic – high ability to preserve the integrity of the CBF product in case of severe damage.

• Ecological, natural material, safe for human health and for the environment.

• 100% recyclable.

Continuous Basalt Fiber (CBF) exhibits physical and mechanical properties comparable to the more expensive carbon fiber, while outperforming fiberglass. CBF boasts a tensile strength ranging from 3000 to 4800 MPa, which is 20–25% higher than that of E-glass fiber and 25–50% greater than steel, alongside a tensile modulus of 85–105 GPa, surpassing E-glass fiber by 10–15%.

Beyond these impressive metrics, CBF possesses unique attributes not found in other fibers, including exceptional bonding affinity with plastics, adhesives, glass, carbon fibers, and other materials. This makes CBF highly adaptable for a variety of manufacturing processes such as weaving, braiding, knitting, molding, filament winding, unidirectional impregnation, pultrusion, 3D printing, chopping, spraying, and other cold-processing technologies.

In numerous applications, CBF is a superior alternative to conventional fibers and demonstrates excellent synergy when integrated with other fibers. This distinctive combination of properties ensures CBF meets the rigorous demands of high-performance, cutting-edge applications.
