Basfiber® for the Automotive Industry
Kamenny Vek provides a range of special products for the automotive industry. Examples include: high-strength basalt roving for filament winding of CNG cylinders, roving and chopped fiber for SMC/BMC technology, chopped fiber for frictional materials, basalt roving for mufflers, basalt woven fabrics and mats for fire protection, heat- and sound insulation, wet-chop fiber for production of easy recyclable headliners.
Car body
Basfiber® has higher strength and elastic modulus than conventional E-glass. Our performance is getting close to special high strength S-glass and carbon fibers. So we offer to car makers an opportunity for significant cost reduction of SMC/BMC parts while maintaining high strength and stiffness. The dielectric properties of basalt fibers are similar to that of glass fibers. Switching from glass to basalt does not change radar transparency.

Basfiber® has 150°C more heat resistance than regular glass fibers. Basalt woven fabrics and mats are ideally suited for the heat and sound insulation of car interiors and engine parts. This creates a safer environment and more comfortable conditions for drivers and passengers.

Automotive Equipment
Kamenny Vek provides high-strength basalt rovings for the filament winding of compressed natural gas (CNG) cylinders. Using our basalt fibers in high-pressure vessels, instead of S-glass, car makers can reduce cost of this product significantly!

Basalt chopped strands are good for use in frictional materials. Brake pads based on Basfiber® have better, and more stable, frictional coefficients and higher endurance than glass fiber reinforced brake pads.
Also, basalt fiber provides many benefits as filler for car mufflers showing great noise reduction properties and good resistance to thermal cycling.

Basalt fiber reinforcement provides much better polymer composite recycling ability than for polymer composites reinforced with E-glass. During the incineration of regular glass fiber reinforced plastics, the melted glass forms a solid mass on the incinerator walls and floor. Basalt fiber reinforced plastics transform into fine powder, which is easy to remove from equipment and to recycle.
