Woven Friction Lining
I. Basic Definition & Overview
Woven Friction Lining (also referred to as Woven Brake Band) is a type of friction material manufactured by fiber weaving technology. It is generally produced by blending and weaving high-performance fibers with metal wires, followed by resin impregnation and high-temperature curing. It is applied to the braking, clutch and power transmission systems of various machinery.
Its core feature lies in the integral woven structure instead of compression molding, delivering outstanding impact resistance, delamination resistance and thermal stability. It is particularly suitable for industrial and marine environments with heavy-load and high-frequency braking conditions. All mainstream products currently adopt an asbestos-free design, complying with modern environmental protection and safety standards.
II. Structure & Material Composition
Fiber Skeleton System (Core Component)
| Fiber Type | Characteristics | Application Scenarios |
|---|---|---|
| Aramid Fiber | High strength, high temperature resistance, low wear | High-performance industrial clutches, heavy-duty braking systems |
| E-Glass Fiber | Moderate cost, good heat resistance, excellent insulation | General industrial braking, elevator systems |
| Copper / Brass Wire | Enhanced thermal conductivity, improved mechanical strength, impact resistance | High-temperature working conditions, heavy-duty equipment, marine environments |
| Cotton Fiber | Good flexibility, low cost, pollution-free | Food machinery, light-duty braking, low-noise required scenarios |
| Ceramic Fiber | Ultra-high temperature stability, extremely low thermal expansion | Braking systems under extreme temperature environments |
2. Bonding Resin System
Phenolic Resin: The most widely used type; features high temperature resistance and strong bonding strength, suitable for most industrial applications.
Cashew Nut Shell Oil Modified Resin: Improves toughness and oil resistance, applicable to humid and oily environments.
Epoxy Resin / Polyimide Resin: Suitable for ultra-high temperature (＞300℃) and heavy-load working conditions.
3. Friction Performance Regulators
Graphite: Reduces fluctuation of friction coefficient, improves wear resistance and self-lubricating property.
Metal Oxides: Adjust friction coefficient and enhance thermal stability.
Sulfides: Optimize high-temperature friction performance and reduce noise and vibration.
