Application of basalt fiber products in automotive industry: thermoplastic compound parts, brake pads, headliners, CNG cylinders and others

Basalt fiber application in automotive industry



Basfiber® products are ideally suited for applications requiring mechanical strength, resistance to high temperature, durability, chemical resistance and environmental friendliness especially when combination of such requirements is needed. Due to its outstanding properties and affordable price, Basfiber® successfully replaces traditional materials in automotive industry for production of:

Basalt materials used in automotive industry

  • Headliners
  • CNG cylinders
  • Brake pads and clutch plates
  • Thermo insulation for exhausting systems
  • Muffler's filler
  • Interior and exterior parts based on fabrics
  • Thermoplastic compound parts and components

Basfiber® advantages

Compared to regular E-glass, Basfiber® shows:

  • 25% higher tensile strength and 15% higher tensile modulus,
  • High impact resistance
  • Extended operating temperature range
  • Excellent recyclability

Green product

According to National Directives on end-of-life vehicles, it is strongly recommended to car manufacturers to use end-of-life management principles during car development and production.

To fulfill such recommendations, car manufactures have to look for new "green" materials which could help them to meet environmental requirements and to ensure maximum recycling when the vehicles reach end-of-life stage.

Many cars and auto parts manufacturers have already chosen Basfiber® as such "green product" due to its advantages:

  • As a raw material for Basfiber® production, we use basalt which is an inert natural rock.
  • No chemical additives are used during Basfiber® production,
  • Basfiber® has no toxic reaction with air, water or other chemicals that may be hazardous for people or pollute the environment,
  • Basfiber® is not a carcinogenic product according to NTP, IARC or OSHA,
  • Excellent end-of-life recyclability in incineration chamber and possibility of further use of black powder that is the product of recycling.

Car's Headliners

Basalt fiber reinforced polymer - car's headliners

Besides excellent mechanical and sound/thermo insulation properties, the key competitive advantage of Basfiber® in this application is its outstanding recyclability which enables car producers to effectively meet strict end-of-life requirements.

Production technologies:

  • Composite based on polypropylene and chopped strand Basfiber,
  • Veils production according to the “paper” technology.

Typical Basfiber® products for this application: wet chopped strand 13 to 16 µm, cut length 12.7mm), covered by KV-05/1 sizing (water compatible).

CNG cylinders

Basalt fiber for filament winding - CNG cylinders

Basfiber® is much lighter than steel, has better mechanical properties than E-glass and is more cost-effective than carbon fiber.

All these advantages, along with excellent recyclability and extended range of working temperatures make Basfiber® extremely promising for production of CNG cylinders.


Production technology: filament winding technology

Typical Basfiber® product for this application: Assembled roving 13 µm, 1200 or 2400 tex, external unwinding, KV42 sizing (compatible with epoxy resin).

Car's brake pads and clutch plates

Basalt fiber brake pads

Basalt chopped strand are used as an alternative to asbestos in production of brake pads and provide the following advantages to final products:

  • 2-3 times longer service life,
  • Extended working temperature range
  • Resistance to chemically aggressive conditions
  • Eco friendliness

Typical Basfiber® products for this application: The 3 or 6 mm chopped strand, 13-16 µm, KV-02M sizing (compatible with phenolic resin).

Muffler's filler

Muffler's filler of basalt fiber

Basfiber® advantages compared to traditional materials:

  • 3 times longer service life,
  • Much higher operating temperature
  • High resistance to thermal cycling
  • Greater noise reduction
  • Lower moisture absorption

Typical Basfiber® products for this application: Assembled roving 17 µm, 2400 or 4800 tex, КV-42 sizing (compatible with epoxy or phenolic resin).

Thermo insulation for exhaust system

Basalt insulation materials for exhaust system

Basfiber® is used for production of thermo insulating sleeves, braids, and fabric for cars exhaust system. The flexible knitted sleeve, when installed on vehicle exhaust pipes, prevents exhaust gases from losing their high temperature as they flow through the exhaust system. The technology enables more complete conversion of gases and particulates, such as CO2 and unburned carbon, in the catalytic converter; the result is better engine effectiveness and less environmentally damaging exhaust effluents.

Typical Basfiber® products for this application: Textured roving for sleeves and braids or high tex twisted yarn (up to 600 tex) for fabrics.

Fabrics for interior and exterior parts

Basalt fabric composite materials for interior and exterior parts

Many interior and exterior parts of cars are traditionally produced from composite materials based on fabrics. Fabrics made with Basfiber are used by some car producers in this application because of its attractive dark-brown color, high mechanical properties, fire-resistance and competitive price.

Thermoplastic parts and components

Thermoplastic compound parts of basalt fiber

Today auto manufacturers widely use thermoplastic fiber composites as alternative to metal to reduce vehicles' weight and cost of production. With its outstanding mechanical properties, resistance to high temperature and "green" advantages, Basfiber® also can be successfully used in this application.
