A non-asbestos woven brake lining roll uses high-temperature resistant yarns like E-glass, aramid, and brass wire. The weft density ranges from 18 to 22 picks per centimeter for optimal flexibility. This woven structure provides a stable dynamic friction coefficient of 0.38 to 0.42. Operating temperatures safely reach 450°C without thermal degradation or fade. The material density is carefully controlled between 1.9 and 2.1 g/cm³. Porosity levels of 20% to 30% allow effective gas dissipation at the contact interface. This unique construction eliminates asbestos fibers while maintaining mechanical integrity under extreme shear stress.
The roll mounts onto brake shoes using high-strength rivets or thermoset adhesive films. Connection spacing of 25 mm ensures uniform pressure distribution across the friction surface. During braking, the woven layer compresses elastically by 0.15 to 0.25 mm. This compression absorbs vibrational energy and reduces audible noise below 75 decibels. Volumetric wear rates measure only 0.20 to 0.30 cm³ per kWh of absorbed energy. The linings thermal diffusivity of 0.45 mm²/s prevents hot spots on mating drums. Consequently, service life exceeds 800 hours in heavy-duty industrial applications like cranes and mining equipment.You can order and buy woven brake lining roll - non asbestos from Iran by contacting us through whatsaap and email.

Materials in Ferodo woven brake lining roll
Ferodo woven brake lining rolls use a multi-component fiber blend without any asbestos. The primary yarn contains E-glass fiber 40-50% by weight for thermal stability up to 650°C . Aramid pulp 15-20% provides high tensile strength exceeding 30 MPa . Brass wire 10-15% is woven directly into the fabric at 20 to 24 picks per centimeter . This brass content improves heat dissipation and reduces surface cracking. Viscose fiber 10-15% adds flexibility during roll bending operations . The woven structure creates a three-dimensional network with 20-30% porosity before resin treatment . Each roll thickness ranges from 5 to 30 millimeters with widths up to 500 millimeters . you can order and buy from Iran.
The woven fabric undergoes impregnation with phenolic resin modified by cashew nutshell liquid CNSL at 25-35% concentration . CNSL acts as a friction modifier and reduces noise during brake engagement. High-temperature curing occurs at 180°C for 4 to 6 hours under 5 MPa pressure . This process creates cross-linked polymer bonds between fibers and resin matrix. Final density measures 1.2 to 2.1 g/cm³ depending on brass content and compaction pressure . The cured lining withstands continuous operation at 250°C and intermittent peaks at 450°C . Chemical additives include barium sulfate 5-10% as wear filler and graphite 3-8% for stable friction coefficient of 0.38 to 0.45 . No bituminous binders are used, ensuring oil resistance for marine and industrial applications . to buy from Iran you can contact us.
