Premium Grade Continuous Basalt Filament Yarn Offering Enhanced Impact Strength and Vibration Damping Performance for Manufacturing High End Automotive Brake Pads and Marine Friction Components
Pasia basalt fiber roving is made of a bundle of parallel strands without twisting. The tensile strength of the roving 7 - 13μm≥0.6N/Tex, the elastic modulus is ≥100Gpa and the elongation at break is ≥3.1%. Compared with the PPTA and UHMWPE, this basalt fiber not only has the high strength, high modulus & excellent shock resistance but high temperature resistance, light resistance, especially, the surface combined with the resin, which has the better binder strength. So the basalt fiber is a kind of inorganic fiber, which can be used as the ballistic & protection material. In the composites, this basalt fiber has the inner explosive prevention function when used in the ballistic material and can prevent the danger from the explosive blast. Furthermore, it has some other advantages such as: no bounce, no spalling, no second execution fracture function, which can be used as the base material for the ceramic facing armoring system.
Our Premium Grade Continuous Basalt Filament Yarn is a high-performance reinforcement material precision-engineered for demanding friction applications in the automotive and marine industries. Derived from natural volcanic basalt rock and processed through advanced filament extrusion technology, this continuous filament yarn delivers an exceptional combination of impact strength, vibration damping, and thermal stability – making it the ideal choice for manufacturing high-end brake pads, clutch plates, and marine friction components.
Unlike chopped or short-cut fibers, our continuous filament construction ensures uniform load distribution, superior interfacial bonding with resin matrices, and consistent mechanical performance throughout the finished component. The yarn is available in various tex counts and can be customized with specialized sizing agents compatible with phenolic or epoxy resin systems.

Key Features
Feature Benefit
Enhanced Impact Strength Exceptional toughness and energy absorption – basalt-reinforced composites demonstrate impact strengths up to 136.25 kJ/m²
Superior Vibration Damping Outstanding damping ratio (0.0644) and stiffness coefficient for reduced NVH (Noise, Vibration, Harshness) in braking systems
High Thermal Stability Continuous service from -260°C to +700°C; short-term peaks up to 960–982°C
Excellent Mechanical Strength Tensile strength of 4,000–4,300 MPa – 15–25% higher than E-glass
High Tensile Modulus 84–87 GPa – 15% higher than conventional E-glass
Moderate Hardness 6–6.5 Mohs – non-aggressive to braking surfaces, reduces rotor/drum wear
Low Friction Coefficient Stable friction performance with reduced heat fading and low noise characteristics
Chemical & Corrosion Resistance Excellent resistance to acids, alkalis, salts, and organic solvents
Low Moisture Absorption < 0.1% – maintains dimensional stability in marine environments
Non-Combustible Limiting Oxygen Index (LOI) > 68% – self-extinguishing, no melt or drip
Applications:
--Filament-winding of various pipes, tanks, and cylinders;
