The friction disc material used in clutches plays a crucial role in the performance, durability, and reliability of the clutch system. Various materials are used for friction discs, each offering different properties and suitability for specific applications.
Organic: Organic friction disc materials are composed of non-metallic materials such as cellulose, aramid fibers, and other organic compounds bonded together with a resin. Organic friction discs offer smooth engagement, good heat dissipation, and low noise levels. They are suitable for light to moderate-duty applications such as passenger vehicles and light trucks. However, they may wear more quickly under heavy loads or aggressive driving conditions.
Feramic (Fiber Ceramic): Feramic friction discs combine organic fibers with ceramic materials to improve heat resistance and durability. Feramic materials offer higher torque capacity, improved wear resistance, and better performance under high-temperature conditions compared to organic materials. They are commonly used in performance vehicles, racing applications, and heavy-duty trucks where higher torque and temperature capabilities are required.
Kevlar: Kevlar is a high-strength synthetic fiber known for its exceptional tensile strength, heat resistance, and durability. Friction discs made with Kevlar fibers offer excellent performance under high temperatures and heavy loads. Kevlar-based friction materials are often used in racing clutches and high-performance vehicles where extreme operating conditions are encountered.
